Lada 2114 Mistress Logbook Help The central locking has stopped working


What to do if the central locking on a VAZ-2114 does not work

Today, all vehicles have a central locking system, which easily and effortlessly makes it possible to open and close all doors with just one click on a special button. It is important to remember that this lock works regardless of whether the vehicle’s engine is turned on or not. It is powered directly from the battery. Due to the fact that the central locking system is autonomous, motorists complain about problems with its operation. This problem also occurred with the VAZ-2114, which is very popular.

Installing silent locks on a VAZ 2107. If you really want to

  • The door armrest, which is secured with three bolts, is unscrewed and removed;
  • The window lifter handle is unfastened (after removing the lock, the handle should be pulled towards you);
  • The inner rim of the decorative trim of the lock opening handle is dismantled;
  • The door card is removed, which is fixed on plastic clips that tend to break during dismantling. Before installing the canvas back, defective elements should be replaced.
  • Holes for the new device are drilled with a drill;
  • The silent mechanism is installed in a prepared place with a pre-cut flag;
  • A special latch is mounted on the lock (popularly called “chocolate”);
  • At this stage, the door will not be able to slam shut because the latch is in contact with the post;
  • Using a circular file, you should adjust the bottom right hole, after which the lock will function normally;
  • Then the outer part of the mechanism is removed to grind down a pair of metal bushings on the side where the lock is pressed against the door. They are designed to accept screws;
  • The corner of the body and the head of the fixing screws are ground down.
  • If there is a problem with locking the door, you need to check for a gap between the lock and the post, carefully eliminating it using a hammer and a wooden block. After adjustment, check the operation of the doors and begin the next stage;
  • Installing a rack screw requires precise determination of its future location. Using a stylus or chalk, snap the “chocolate” twice, pressing it against the seal. The stylus will serve as a kind of pointer, using the marks of which the location for installing the screw is determined. It is advisable to repeat the snapping procedure several times to know for sure where the screw will be;
  • A hole with a diameter of 8 mm is drilled on the wall of the rack. After cutting the internal thread, the screw is mounted. So that it does not interfere with the closing of the door, it is necessary to recess it as much as possible into the groove until the desired effect is obtained;
  • A hole with a diameter of 11 mm is made in the front wall, and 9 mm in the rear. The screw is screwed into the rack with additional fixation with epoxy glue;
  • The doors are adjusted by loosening the screws and moving the lock until the desired result is obtained.

Causes of central locking malfunction

Our experts include the following as the main reasons for the failure of the VAZ-2114 central locking system:

  1. Impact of climatic conditions.
  2. Incorrect installation and adjustment of the lock.

Before contacting a specialist, the car owner can independently conduct an inspection, thanks to which he will determine the next steps. If the car makes sounds that indicate that the door is opening or closing, you will need to remove (unscrew) the latches and then close the door. A single door closing indicates that new ones need to be purchased.

Our experts advise checking the condition of the internal part of the central locking system. The reason that the lock does not work may be a lack of lubrication on the wires. Processing needs to be done.

A weak charge on the control panel (remote) can be another reason why the door mechanism cannot operate. It is quite possible to fix the problem by replacing the batteries or buying a new remote control.

The inoperability of the VAZ-2114 central locking system may also depend on climatic conditions. Low temperature leads to icing of the signal transmission system. Moisture also affects the operation of the lock. The remarkable thing is that it is very easy to solve this problem. It is necessary to literally dry the wet areas of the central locking system (central locking).

All of the above reasons that prevent the VAZ-2114 central locking system from working fully are quite simple and can be eliminated independently. But it is worth noting that there are a number of reasons that have quite complex defects. These include a blown central locking fuse, the operation of which depends on the environment (temperature), namely:

  • heat;
  • cold air.

When hypothermia occurs, the entire operation pattern is disrupted and the lock becomes unusable. As a result, the central locking does not respond to signal impulses. It is noteworthy that high ambient temperatures can cause the system to short out.

Central locking key fob burned out

It is worth paying attention to the fact that you can check the condition of the VAZ-2114 central lock key fob using a multimeter. They can track the voltage of the contacts responsible for the operating state of the contacts and for the operation of all car doors. If the VAZ-2114 car lock control unit does not show any operating signs, you should make sure that it can be restored. To do this, it is necessary to carry out diagnostics and replace the mechanism with a new one.

We advise you to pay attention to any breakdowns that occur in a timely manner and fix them yourself or with the help of specialists.

Central locking VAZ 2114: principle of operation, causes of malfunctions and methods for eliminating them

For how many years now, motorists all over the world have been complaining about the malfunction of the central locking system and often ask the question: “Why is this happening, and what are the reasons for this?” The answer to this question can be obtained from a detailed examination of the very principle of operation of the central lock and its capabilities.

It is known that almost all modern cars have a special automated system that allows you to open and close the car door with just the press of a button. This is the central lock, and as it turns out, some problems may arise due to its autonomy. This dilemma has not spared the domestic VAZ 2114, which for many has long become indispensable.

Operating principle of central locking

First, let's figure out what is the operating principle of the central locking on a VAZ 2114? The operation of the central lock involves transmitting signal control to a certain point, followed by activation of the relay. As a result of this, when you press the button on the key fob, the car door will be closed, or vice versa - open. A fairly simple explanation.

However, this is enough to highlight the first central locking problem that everyone is dealing with. This, as you might guess, is a technical question. In other words, the internal state of the device.

As we already know, central locking is controlled on the principle of transmitting a control signal from point A to point B. This is where the rub lies, which can be explained for a number of reasons.

  • incorrect installation of the device or incorrect settings;
  • climate impact.

Principle of operation

How is the central locking system controlled on the VAZ-2114? The algorithm of the central locking operation is that a control pulse arrives at a certain point, as a result of which one relay with power contacts is activated. In one case the car is locked, in the other - vice versa. Central locking activators are connected to relay contact 30, and through closed contact 87, ground acts on both outputs of the activator. If one or another relay is triggered, then contact 30 will be connected to the positive, and as a result, temporary voltage will be supplied to the activator, which will set the rod in motion, which will either open or close the door. Taking into account the fact that all activators are connected to the central locking system in parallel, one action will be the same for all doors. The locks installed on cars can be electric or pneumatic. The electric central locking system consists of mechanisms with a single motor, the second, in turn, includes a compressor, tubes and a control panel.

Troubleshooting options

The problems seem quite serious. But don’t rush to get upset. Knowing these reasons, you can ask yourself the question: “Why does the central locking on the VAZ 2114 not work? What is the problem?"

First, you need to conduct an independent diagnosis, which will allow you to determine further action. If the car makes the sound of the doors closing, but nothing happens, then you should unscrew the door locks and then lock the car. If the doors close only once, you should buy new ones with the appropriate diameter to repair them.

Experts' opinions

Many experts who have encountered the problem that the central locking on a VAZ-2114 does not work argue that all problems with the device should be divided into certain categories. Below we will look at each of them.

Problem categories:

  • Complete device failure.
  • Partial lock failure.
  • Operation malfunctions due to mechanical, electrical or other defects.
  • If a problem occurs with the central locking, the car owner must independently determine which of the above categories the breakdown falls into. Therefore, repairing a fault should not begin with disassembling a particular unit - it is enough to conduct a thorough diagnosis of the equipment. Thanks to the diagnostics carried out, the car owner will not only reduce the time spent searching and solving the problem, but will also reduce the monetary costs of repairs. Firstly, the central door lock on the VAZ-2114 works regardless of the engine or ignition. The main thing for the central locker is the presence of a working on-board network. The serviceability of the BS lies in the correct connection of the vehicle's power terminals to the battery. Experts say that the simplest reason for the malfunction is that the walls of the door tongues are too thick, which cannot move freely through the trim. As a result, the activator is simply unable to close the doors, and at the same time reproduces clicks of completed work. You can check it in a simple way - just unscrew the locks from the doors and close the car. If all the doors close once, you will have to buy new clamps with a smaller outer diameter.

Other system failure options

The above problems are the main causes of damage. However, there is a more complex mechanism, the defect of which cannot be ignored.

It happens that with the manual activation method the central lock is not operational. In this particular case, most likely the VAZ 2114 central locking fuse is not working. Its condition depends on the ambient temperature. Due to hypothermia, malfunction occurs and it fails, as a result of which nothing happens. The central locking system does not respond to signal impulses. Another reason is high temperature, which causes a short circuit.

Fact: Often, central locking works intermittently in certain places. This is usually caused by electromagnetic interference.

Why did the VAZ 2114 central locking unit burn out and what to do?

The solution to this problem is based on the use of a special device - a multimeter. Using it, you can check the voltages of those contacts that are responsible for activating the remaining doors. What to do if the central locking control unit on a VAZ 2114 does not work and does not show any signs of life? In this case, you need to make sure that it can be restored by first diagnosing its condition and, if necessary, restore it or buy a new one.

Educational information: The central locking on the VAZ 2114 is very sensitive. To increase reliability and durability, it is recommended to avoid places of high humidity and direct exposure of the device to rays.

For an amateur or a specialist, a breakdown in a car is always an unpleasant moment. However, having some knowledge of breakdown problems and ways to solve them, you can significantly simplify your life by easily correcting the central locking malfunction.

Central locking drive failure

If all the wiring is in good condition, then it also happens that the main activator, which closes the central locking on the VAZ-2114, breaks down. To solve the problem, just purchase a new main door activator. Just remember that you should buy a lock drive that has 5 wires, not 2. Since the five-wire one is installed on the control door, and the two-wire one is installed only on the controlled part.

So, we have looked at the main malfunctions that occur with the central locking on domestic Samara-2 cars.

Why the VAZ-2114 central locking does not work and repairs

Cars rolling off the assembly line of the Volzhsky Automobile Plant have long established themselves as reliable and trouble-free vehicles, whose distinguishing features are ease of operation and ease of maintenance.
However, unfortunately, like any other mechanisms, they sometimes break down. According to reviews from owners, the central lock is considered a rather vulnerable element. It has several specific features, without knowing which it will not be possible to get rid of the problem without the help of a professional repairman. So for what reason does the central locking not work specifically on the VAZ-2114? Let's figure it out.

General useful information

The central lock itself (abbreviated as CZ) is a special locking mechanism that ensures all doors close at once. This device significantly increases the operating comfort of the car, as it eliminates the need to lock it manually. When installing an anti-theft alarm system, the functionality of the central locking system increases significantly.

The lock functions regardless of whether the power plant is turned on or not - it receives power directly from the battery.

As a rule, breakdowns of the locking device lead to certain difficulties with:

  • closing individual doors;
  • seizures;
  • repeated slipping of the mechanism, etc.

There are several most common reasons that cause this kind of trouble, and we will talk about all of them below.

By the way, not all car owners know where exactly the central locking is located in their VAZ-2114. You need to look for it directly in the driver's door. An electric drive is also installed here. Other elements are distributed between other doors. The control unit (the brain of the central locking system) is located behind the dashboard.

What can happen to the lock - the seven most common breakdowns

Why did the central lock installed on the VAZ-2114 stop functioning normally? For the most part, failures occur in very wet weather or due to sudden temperature changes.

Signs of impending problems include:

  • jamming;
  • partial (or fuzzy) operation;
  • Too loud clanging and noise from the gearbox.

First of all, failures occur due to the failure of the electromagnetic relay that controls the central locking power supply. It’s not difficult to make sure that it’s the culprit – it’s enough to install a known good one in its place.

An electrical short is also a common cause of central locking failure. Finding the problem here will be much more difficult. You will need to test the wiring in the circuit using a multimeter, starting with the battery. Before checking, do not forget to disconnect the negative terminal on the battery.

Damage to circuit integrity. In some places, the veins become unusable over time due to constant friction. In particular, the insulation may deteriorate or the wiring may break. There is a risk of loss of contact due to loosening of the connectors or their oxidation.

The design of the central lock has special springs, similar in shape to the letter “G”. Their purpose is to help when traction is triggered. However, over time, they stretch and, conversely, begin to impede the free movement of the above-mentioned element. The easiest solution is to simply remove all these springs. Their absence does not in any way affect the performance of the central locking system.

Failure of the central locking unit is very rare, however, the likelihood of such a breakdown should not be discounted. A regular tester will help you deal with the problem. In particular, you should measure the voltage directly at the contacts coming out of the block. It is not specific indicators that are of interest, but the very fact of the presence of nutrition. In the absence of a multimeter, the test is carried out differently:

  • take a long enough wire;
  • one end of it is connected to the battery negative;
  • the second - to the BCZ;
  • then an attempt is made to close/open the lock.

The absence of a result clearly indicates a node failure.
Also, due to certain overloads, the fuse often blows. This, in particular, is facilitated by the difficult movement of rods, etc. Often similar problems occur with cars that have undergone tuning in handicraft workshops, during which the door trims were replaced. Because of this, the gap under the casing is reduced, which prevents the walker from working normally. As a result, the servo requires more force to move the rods, which overloads the chain.

How the central lock works

The central locking algorithm consists of sending an impulse to the VAZ 2114 central locking control unit, which analyzes the received signal and generates commands that control the door locks. They are either opened or locked.

General scheme of central locking

Elements that activate the central locking are connected to pin 30. If contact 87 closes, then the activator outputs will be affected by ground. When a certain relay 30 is activated, the contact will connect to the positive. Thus, the activator will receive power and the rod will begin to move. The control unit rod closes different pairs of signals depending on what action needs to be performed: closing or opening the doors.

Since the central locking activators are connected in parallel, all doors will either open or lock at the same time. Central locking can be pneumatic or electric. The first type of device includes a control panel, compressor and tubes. In an electric one, the main element is a motor, thanks to which the mechanisms are activated.

Examination

EXECUTION ORDER
1.
The central locking system uses two-way solenoids to lock and unlock the doors. Lock switches have two operating states: Locked and Unlocked. These switches operate a relay, which in turn supplies voltage to the door lock solenoids. Depending on what signal is sent to the relay, it changes its polarity, allowing both parts of the circuit to have a positive or negative voltage.
2.
Always check the electrical circuit protection first. Some vehicles use circuit breakers and fuses together.
3.
Switch the switches to both positions (Lock and Unlock) with the engine off. Listen to the faint click of the relay being activated.
4.
If you do not hear a click, check for voltage at the switches. If voltage is present, check the wires between the fuse box and the switches for shorts or opens.
5.
If voltage is present, but no click is heard, check the switch for current continuity. Replace the switch if it does not conduct current in any of the positions (see table. Table of connection of the tester and conductivity of the main block of switches for the central locking system).
6.
If the switch is conducting but the relay does not click, check the wires between the switch and the relay. Reestablish the connection if there is a break in the circuit.
7.
If the relay receives power from the switch but does not send it to the solenoids, check that the relay case is properly grounded. If the relay case ground is OK, replace the relay.
8.
If the solenoids of all locks work except one, remove the trim panel from that door (see subsection 11.12) and check for voltage on the solenoid when the lock switch is turned on/off. There should be voltage on one of the wires when the switch is in the closed position; the second wire must be live when the switch is in the open position.
9.
If voltage is present at the inoperative solenoid, replace it.
10.
If there is no voltage at the inoperative solenoid, check the wire between the solenoid and the relay for an open.
Warning
Wires often break in the part of the wiring harness that is located between the body and the door (constant opening and closing of the door leads to the accumulation of fatigue in the wires and, ultimately, to wire rupture).

Possible malfunctions of the locking system

If there is no reaction when you turn the key in the lock or press a key on the remote control, this means that the central locking is not working.

All causes of central locking malfunction can be divided into two types:

  • technical;
  • related to climatic phenomena.

In the first case, breakdowns are possible due to incorrect installation or configuration of the locking system. Subject to natural wear and tear after long-term use. The service life directly depends on the quality of the device.

In the second case, the central locking system may fail under the influence of low temperatures and it may freeze. The lock may not work if water gets into the mechanism during rain or melting snow.

The central locking system may not work due to an incorrectly installed or faulty alarm system. In this case, you should diagnose the locking system. The control activator is installed in the driver's door. As soon as the drive is activated, signals are sent through the appropriate channels to the remaining activators, according to which the required action is performed. Therefore, you should check the operation of the lock using the key and the button on the key fob.

If the doors sometimes close, sometimes they don’t, then the reason may be in the control circuit or a violation of the integrity of the electrical circuit of the car alarm. The reason why the central locking system fails to operate may be insufficient battery charge or a blown fuse. Depending on the circuit being used, there may be multiple fuses. They all need to be checked and faulty ones replaced.

The fuse can burn out as soon as it is installed, due to a short circuit or overload, for example, when controlling the central locking with a key fob, and not manually. In warm weather, the reason is a short circuit, which is possible due to poor contacts or an open circuit. The cause of the breakdown may be a malfunction of the central locking control unit.

You can check the operation of the unit using a multimeter by checking the power supply to the activators. Current is supplied to the contacts of the unit by unlocking and locking the driver's door. If the control unit is broken, it needs to be replaced.

Diagnosis of alarm malfunction

The central locking control activator is installed in the driver's door. As soon as this drive is activated, a signal is sent through the channels of the circuit between the remaining activators, according to which the desired action occurs. If an alarm system is installed on the car, the performance check should begin with it. To do this, you need to check the closure both with the key and with the key fob. If the car closes completely from the first, but not from the second, then the problem lies in the electrical alarm circuit or in the control circuit. It happens that the simplest reason for the car not being locked with the key fob is the weak charge used in the battery. It happens that even with the manual method the central locking does not work. If a vacuum central locking system is used, then during manual testing there will be no sound of the compressor running. With electric central locking, you will hear characteristic clicks produced by the relay. However, the buttons on all doors will remain in the same position. Most often, domestic cars use electrical central locking systems. In such cases, the VAZ-2114 central locking fuse has probably failed. Depending on the connection circuit used, more than one fuse may need to be replaced. This repair can quickly end.

Repair features

If the central locking of the VAZ 2114 has stopped working, then you need to conduct diagnostics and find the cause of the breakdown (the author of the video is Nikolay Bogdanov).

Then carry out the appropriate repairs. Problems with central locking on the VAZ 2114 most often arise at low temperatures and high humidity. The reason is the locks with solenoids that are installed from the factory. It is better to replace them with locks with an electric motor.

If the drive is not working on only one door, it is necessary to check its electrical circuit for an open circuit by testing it. Most often, broken wires are located in the corrugation. Since the doors are opened and closed frequently, the insulation cannot withstand the load. The break is restored by replacing the wire and connecting the broken sections using female-male terminals.

If there is no break, the cause may be a failure of the control board or switching relay. The winding of the motor or solenoid may burn out, and the drive gears may wear out. In this case, the door auxiliary drive may need to be replaced.

Repair of electric central locking

The central locking system on a VAZ-2114 of this type begins to work intermittently after a while. They will be associated with temperature fluctuations. Most often, unstable operation of an electric central locking system will be observed at low temperatures or high air humidity, that is, in the autumn-winter period. At first, the mechanisms will jam slightly, then opening or closing will not occur at all. Most often, this problem occurs on domestic cars with pre-installed central locking from the manufacturer. It is better to replace locks with solenoids installed at the factory with central locking systems with motors, which will be more reliable. If the drive of one door does not work, you should check the circuit to that door. If there is no open circuit, then the problem may lie in a malfunction of the switching relay or a breakdown of the activator control board. Sometimes the solenoid or motor winding may burn out, or the drive gear may wear out. In this case, it may be necessary to replace the auxiliary drive of the central locking door.

Installation instructions for central locking

Before installing the central locking system, you should study the connection diagram

Photo gallery “Central locking diagrams”

The central locking control module is located on the left side under the panel. There are 6 wires coming from it. To install the central locking system, you need to disconnect the brown and blue wires.

Before connecting, you need to check that activators with 5 outputs are installed in the doors. If they are missing, they should be installed.

In a VAZ 2114 car, the wire responsible for opening the doors is usually white and connected to terminal 7. If there is no connection to terminals 7 - 5, then the 8th terminal is connected to the brown wire. This wire is responsible for opening the doors. Terminals 5 and 6 are for closing doors.

To install the central locking system, you must purchase additional items:

  • 2-3 diodes 1N4001 at 1A;
  • one diode 1N5401 3 A;
  • 2 diodes of 4 or 5 A, if there are no separate outputs for turn signals.

After connecting the central locking system to the alarm, you need to check its functionality.

Connecting the central lock

First you need to study in detail the connection diagram for the central locking on a VAZ car - 2115,2114. Finding it is not a problem by searching on the Internet.

The central locking control module is located on the left under the dashboard. Looking there, you will find six wires coming out of the module housing. To install the alarm, you must disconnect the blue and brown cords. As a result, we get a connection corresponding to the following diagram:

Before connecting the alarm, you should make sure that it is not a toggle switch installed on the driver's door, but a standard actuator with five outputs. Otherwise, you will need to install an actuator, which is quite problematic.

On VAZ -2115,2114 cars, the white wire, which is connected to the seventh terminal, is usually responsible for unlocking. If there are no connections at terminals 7 and 5, then the eighth terminal is connected to the brown cord. It is this cord that is responsible for unlocking in this case.

Terminals number five and six are responsible for locking the lock. This arrangement of contacts is typical for almost all blocks of the “ninth” series.

For some reason, none of the instructions for alarms ever indicate that installation requires the purchase of additional elements.

We will definitely need:

  • Two to three 1N4001 diodes per Ampere
  • One 1N5401 3 Ampere diode
  • Two 4 or 5 Ampere diodes if there are no separate outputs for turn signals.

When installing a Starline alarm system, the task is greatly simplified, since significantly fewer additional parts are needed.

The central locking in the car does not work

Central locking (CL) is a very convenient thing that allows you to lock or unlock all the car doors at once with a slight movement of your hand. However, sometimes this system does not work correctly or does not respond at all to turning a key or pressing a button. What could be the reasons for a central locking malfunction?

Often the central locking, especially on domestic cars VAZ-2110, VAZ-2114, VAZ-2115 and their derivatives, begins to act up. It manifests itself like this: when you close the driver's door with the key, the other doors do not respond. If you move the key a little, the central locking works. Why is this happening?

Contacts in the main drive do not close

The central locking, powered by the driver's door lock, functions as follows: an electric drive is installed in the specified door, which not only controls its lock, but also sends signals to the central locking unit. The block distributes corresponding signals to drives installed in other doors.

The control actuator in the driver's door has five wires

For these purposes, an actuator is installed in the driver's door not with two, as usual, wires, but with five. Via additional wires, the drive “communicates” with the central locking unit. When the lock is locked, the driver's door control rod lowers and closes certain contacts inside its housing. The central locking unit receives voltage and gives a command to the lock drives of other doors to close. The same thing happens when opening, only the voltage flows through other wires and through other contacts, making it clear to the central locking unit that it needs to send a command to unlock the door locks.

In this case, the contacts inside the control drive may not always close at the right time. For example, this may occur due to improper adjustment of the linkage that connects the lock button on the door and the electric drive itself. That is, the button may already rest against the casing, preventing the rod from lowering further, but the contacts in the drive have not yet closed. Accordingly, it seems that the lock is locked (it may actually be locked on the driver’s door), but the other doors will not lock, since the rod needs to be lowered another couple of millimeters.

The same phenomenon occasionally occurs on the VAZ-2110, when the button gets pinched against the door trim and also prevents the rod from descending to the required depth. The most important “trick” is that this lowering may be enough for the mechanical lock to lock and it seems that the door is locked, and accordingly thoughts come about a malfunction of the entire central locking system. This is wrong.

When the central locking behaves this way, first of all you should make sure that the button is lowered all the way. To do this, with the door open, click the lock latch two clicks, simulating a closed door, turn the key and try to lower the button with your hand. If the central locking works, then you need to release the lock button from its tight contact with the door trim or adjust the linkage from it to the control drive.

Central locking fuse blown

If the central locking still does not respond to locking and unlocking the driver's door, then the problem is most likely electrical. The simplest reason is a blown fuse. Moreover, in the case of a central lock, it can burn out not only from a short circuit, but also from a normal overload. This happens when it is too difficult for the drives to move the lock rods, for example, due to improper adjustment of the rods or congealed lubricant in the lock. frozen locks using the key fob .

Broken central locking wires

Another reason why the central lock may not work completely or partially is a broken wire. Moreover, the wires break, as a rule, in those places where they are subject to bending loads - the entrance from the body pillar to the door. The driver's door is the most frequently opened door in any car, and the control drive is located there. This means that it is enough to break at least one wire that enters it from the rack and relates to the central lock, and the entire locking system may begin to work incorrectly.

Schematic diagram of the electrical system of the central locking system

It is quite easy to determine this malfunction. You need to carefully remove one of the ends of the rubber corrugation along which the wires enter the door, and pull the necessary wires towards you. Which wires are responsible for the central locking can be found out from the car's electrical diagram. If this information is not available, you can pull all the wires separately.

The point of such a check is that the broken wire will be pulled out of the common harness. Here you can also pull out the other end to connect them and thus repair the central lock. You can connect the wires by twisting them, or you can use male-female terminals

.
Naturally, any such connection will need to be wrapped with electrical tape
.

Wires can be broken in other places, but this is rare. If this does happen, you need to use a multimeter to call the entire electrical network of the central locking system and find a break. This requires some knowledge of automotive electrical engineering and the ability to use a multimeter.

Central locking unit burned out

Another reason why the central locking may not work is the combustion of the central locking unit. To diagnose it, you also need to use a multimeter and determine the presence of voltage on the contacts to which the drives of other doors are connected. The control drive in the driver's door must at this time supply current to the corresponding contacts of the unit (the lock must be unlocked or locked with a key).

The central locking activator is faulty

And finally, the reason for the central locking failure may be in the control drive itself (they are also called activators), or more precisely, in its contact group. The contacts may oxidize or break off, and then the drive will not be able to send the appropriate signal to the unit - the other doors will not respond to turning the key in the driver's door lock.

In this case, you will need to replace the electric drive with a working one. Find out what drive is in your car and buy a similar one. If the drive is a regular common activator, then buy the same one. The most important thing is that it has five wires, because activators with two wires are responsible only for locking and unlocking the lock and do not send signals to the central locking unit.

Where is the VAZ 2115 central locking fuse?

Dear visitors of the “Cars” website! We will be very grateful for your comments on the video clip “Where is the VAZ 2115 central locking fuse located?” registration is not required for this. We also ask you to let us know if you have any problems playing the video.

There is a button and two jumpers on the block, what are they for? Skills problem: long pulse of the siren horn and flashes of turns, how to reduce the time? Can this be done with a button or jumpers? Thank you in advance. 

Who knows, if there is a 5-pin actuator on the driver's door, how to connect it?

good afternoon, tell me what wire is on the door switches

It's called a solenoid

hi, I have a more interesting problem, the standard central locking of a Ford Focus 1 control the lock from one wire, you give + closes, you give - it opens, if you connect one white wire, it only works to open, if you connect both wires together, then when you press the button, close closes, and when you press the unlock button unlocks and immediately closes, please tell me what to do, thanks in advance

I bought the alarm here

Thank you, it was very helpful. Like me. Just help me with the drive actuator. sides. Where to put the 3 ends. 

Hello. The package arrived today. the same central locking unit. Please write where exactly which wires should be connected? very necessary. thanks in advance 

Very useful video Thanks more Just ordered, will install soon

What are the two connectors near the main plug for? what can you do with them??? 

in the CYCLON RD-33 model there is a red-black wire for opening the trunk, you have a blue one, but there is no button for opening the trunk; there is a type of lightning and car search. What should you do? Do you need to finish something??? Or is there no such function and then we clamp the wire? 

In the instructions in English on page 3, see Figure D, this is the most common connection diagram. In principle, this was chewed up in the video... 

Thank you Helpful

Uh, I don’t remember what it’s called... and a life story is a must for the instructions

Maybe someone can tell me if the central locking will work from a 12V 11Ah motorcycle battery. And how long will it last? 

when you press close it opens because it goes to the bottom and when you close it to the top it turns out that the door opens what could be the problem if you swap the wires, will something change?

Thank you Everything is short, clear and understandable. I also bought this c. h, there is no time to understand, there are several connection options in the diagram. 

Can you tell me if the car had a c. z from the factory and I want to install this unit to use the key fob remotely, which circuit should I use? 

Thank you, I connected everything and it works
