Daewoo Nexia alarm connection points

In this condition, you can go to the car market or store to buy spare parts.

Replacing the ignition switch on a Daewoo Nexia. It’s very simple.

The situation is certainly terrible, especially for an ordinary car enthusiast with no experience in car repair. When the frame is completely lowered, a gap forms in the upper part, and this is where the needle needs to rest, to prevent the frame from returning. This was the first thought that came to me, and as it turned out, it was wrong.

Daewoo Nexia. Photo report. Photo report on replacing the ignition switch cylinder. attention!! 1 meter photos: o. 1. here...

Using an L-shaped device, press the latch through the hole in the lock body. Secondly, new is so new.

This operation is carried out with a short and thin screwdriver, since the screw we need is located in a place that is limited for access, namely on the inside of the switch.

Again, we do everything carefully - there is one thing with a spring, it doesn’t seem to fly, but it can fall out and get lost. Carefully pull out the key from the ignition, while securing the locks on both sides so that they don’t fall out. Slowly and carefully change the locks from one cylinder to another. If you mix it up, the larva will not turn the key!

On the side we do it in reverse order. Tags: I didn’t buy the original larva, there was also a hook, I broke it off with pliers. It was not possible to insert it correctly the first time; apparently the pin was placed in the wrong position in the plastic hole of the contact group.

It was not possible to unscrew the screw securing the contact group, so I simply disassembled the 3 latches, then set the pin and hole in the plastic of the contact group to the required position and everything worked with a bang. The entire block is held on by two screws.

A screw for removing the contact group and a hole for releasing the latch. What a bummer. The rest of the rod is inside the lock.

A knitting needle is best suited. There is a plate inside that needs to be lowered down with a screwdriver and secured on the back side when installing the cylinder. This is how the lock is connected to the contact group.

When installing the larva, the tongue needs to be filed a little, otherwise you won’t install it. Whole set of new inserts. Also add a 24mm wrench to remove the steering wheel and a plus screwdriver to remove the steering wheel cover.

How to save the old key when replacing the Nexia ignition lock cylinder

Finally, the new larva is in place. If you bought a high-quality larva, the procedure does not cause any problems. The installation becomes more complicated in cases where the driver decided to save money and purchased a Chinese product. Many experienced motorists claim that it may not fit into the body.

Replacing the ignition lock cylinder and contact group Nexia Opel Matiz and similar

How to install a new contact group on the ignition switch? If it doesn’t bother us that we will have one key for the door and trunk lock, and a second one for the ignition switch, we’ll spend rubles and put a new cylinder in place.

If it bothers you, you will have to change all the larvae and pay five times more. Korean ignition lock cylinder. Set of cylinders for all locks. Replacing the ignition switch on a Daewoo Nexia We have already removed both steering column covers and the contact group, all that remains is to remove the old one and install the new cylinder in place.

The only tools we need are a metal rod mm thick, a hex L-shaped key, a wire bent in the shape of an L, or, at worst, an ordinary large paper clip or pin. The operation is not very convenient, so don’t be upset that it doesn’t work out the first time. This is how it was intended Marina Please tell me! Yuri Ildar, I also have no petal, how did you manage to change the larva?

You need a very thin and short screwdriver to remove the contact group, a good person at work made it out of wire on a machine, then it was worse, I couldn’t remove the cylinder for half a day, then I started it with a screwdriver, and since the power steering is in place and accordingly the steering wheel began to turn much easier and Literally pressing the fact that the 2mm larva literally pops out.

Tell me what could be the problem?

That is, they did not go out, and the key itself turned suspiciously easily. I think the contact group of the ignition switch is covered.

How to replace the Daewoo Nexia ignition switch with your own hands?

1. Disconnect the negative terminal from the battery. Use a Phillips screwdriver to remove the screws that secure the plastic covers to the steering column and remove the two halves.
2. Remove the connectors suitable for the contact group. Use a thin, short screwdriver to remove the retaining screw located on the inside of the ignition switch; note that its accessibility is limited.
3. The cause of the malfunction may be a breakage of the shank on the cylinder of the lock itself. Pull out the cylinder, for this you will need a wire or pin with a suitable diameter, about 2-3 mm, bend it at a right angle using a hexagon, and press through the hole onto the latch. At the same time turn the key to the second position. If everything is done correctly, this will allow the larva to come out of the body by five millimeters on its own; all you have to do is remove it. It is not recommended to remove the ignition switch assembly with the cylinder, as this is a very labor-intensive process; you will have to remove the entire steering column to be able to get to its mounting bolts.
4. If you have not taken care of purchasing the necessary components in advance, then at this stage you can easily drive to the nearest automobile store or market and buy spare parts that require replacement. You can turn off the car using a contact group and a screwdriver.
5. As a rule, there are two ways to solve this problem. In the first case, you can buy and replace only the ignition switch cylinder. This option is quite common and is the cheapest and fastest, but it will require you to always carry two keys with you, since the ignition key will be different from the key that opens the doors and trunk. In the second case, you can purchase a set of cylinders, which will include the cylinders of the ignition switch, trunk and front doors. The replacement process in this option will be more labor-intensive and will cost a little more, but you will have one key for everything. Which method to choose is up to you.
6. Assembly is carried out in reverse order. Insert the new cylinder inside the ignition switch housing, together with the key in position 2, while simultaneously pressing the lock with wire. The most important thing is not to stumble upon a cheap Chinese counterfeit cylinder, because if you try to install it in the lock body, a problem will arise, you simply cannot do this, it will not fit there. The remaining options for larvae manufacturers are of quite high quality and can easily withstand replacement; they are installed the first time, just like factory ones.

Removing the door trim yourself

The Nexia driver's door lock is located under the decorative panel, which must be removed. Regardless of which door is disassembled: rear or front, work is carried out from the interior. Basic steps: studying the diagram, dismantling the handle, removing the casing, gaining access to the device. Algorithm of actions:

1. Remove the plugs. Unscrew the handle screws. Remove the top trim.
2. Detach the upper part of the cladding by unfastening the plastic clips.
3. Disconnect the wiring from the speakers and power windows.
4. Unfasten the lower part of the trim. Remove the panel.
5. Unscrew the fasteners holding the lock.

Now the locking element on the Daewoo Nexia can be inspected, the cause of the breakdown can be identified, and repairs can be carried out.

Good to know…

If you want to save money and buy only the cylinder itself, and at the same time have only one key left, then there is another option that is useful to know about. It will consist in the interchangeability of secrets between the old and new ignition lock cylinder.

1. Turn the cylinder, or rather its inner part, until the lock stops, press it with a screwdriver and disengage it. Be very careful when performing this procedure as the retainer and spring may come loose and become lost. There is also a locking tab on the opposite side of the larva; you should also keep an eye on it and protect it from loss.
2. By analogy, it is necessary to take the same actions with a new larva.
3. Compare the sizes of the secrets with each other.
4. If the secrets are the same, you can start replacing them. Change each secret in turn and make sure not to confuse the location of each of them; if the position of at least one is incorrect, the cylinder key will no longer turn.
5. If the secretions of the new larva differ in size, then you will have to replace it using one of the methods described earlier.

Front door lock device

The Nexia door lock has teeth that rotate when you turn the key. When the pins diverge, the door opens; when they converge, the door closes. The movement is facilitated by the presence of grooves where the teeth fit. If one of the parts breaks or rusts, movement will be difficult and the mechanism will lock. If the blade is jammed and does not open, it means that the pins have not completed their journey due to a violation of the encoding.

During the repair you will need:

• flat, Phillips screwdrivers;
• straight thin knitting needle or thick needle;
• wrenches 10mm, 12mm.

Dismantling

First, you need to remove the old lock in order to install a technically sound one. This is done in several stages:

1. Start the work by removing the terminal from the battery using a ten key. Use a Phillips screwdriver to unscrew the screws securing the steering column casing. To access the top screws, turn the steering wheel. You can remove the steering wheel completely, but this is not necessary.
2. After removing the steering column trim, access to the electrical mechanism we need opens up. Before removing the ignition switch on the Daewoo Nexia, you should disconnect the contact group from it. Using a Phillips screwdriver, unscrew the fastening screw and, as carefully as possible, remove the contact group, which looks like two small rings.
3. Dismantle the cylinder: unscrew the fastening bolts from the lock using a screwdriver, knock it down with gentle blows.
4. When disassembling the structure, it is necessary to check the condition of the contact group, since the cause of the malfunction may be in it. In this case, replace the element.

When the faulty mechanism is removed, proceed to install the new one.

Installation

Having established the cause of the breakdown, go shopping. Remember: for cars of different years of manufacture or assembled in different countries, certain lock options are provided. We recommend using the VIN number to determine the type of mechanism. Be sure to purchase new screws to secure the pieces as they are permanent.

To insert a new lock on a Daewoo Nexia, you will have to perform a series of actions as during dismantling, but in the reverse order.

1. We install the lock on the seat and securely fix the bolts.
2. We connect the contact group to the lock using a screw.
3. We fix the steering column trim. Access to the upper holes of the mounting screws is possible by turning the steering wheel.
4. Screw on the battery terminal.

Summary

Before changing the ignition switch on a Daewoo Nexia, it is worth considering that some inconveniences may arise. It is impossible to use the same key to start the engine and open the doors or trunk. The old one will perform the function of opening the doors and trunk, and the new one will start the car. If you are not ready to use two different keys, then you should change all the locking mechanisms at once. This can also be done without outside intervention because the remaining locks are easier to dismantle.

The option of replacing the secret of a new lock is not always suitable. To do this, you need to be careful, and perhaps have technical knowledge: there is a high probability that during the dismantling process the plastic decorative ring will be damaged and the metal protective ring that secures the cylinder in the structure will be scratched.

The procedure is carried out as follows:

1. The key is inserted into the keyhole, turned as it unlocks, and pressed into the hole with a wire or knitting needle. When the larva reaches 5mm, remove it using improvised means. If you mix up the secrets, the electric mechanism will stop working.
2. The larva itself has a cotter pin secured by a spring. To pull it out, you need to press down and turn the key towards the ignition. The cotter pin is released from the clamps and flies out, as the spring acts on it.
3. It is now possible to configure the secret to match the old lock.

PS

On a Daewoo Nexia, the ignition key opens the doors and trunk. Accordingly, when replacing the mechanism, this function will be lost. The driver will have to use two keys, which is not very convenient and often leads to confusion. The problem can be solved in two ways:

• Purchasing a new set of cylinders for the ignition switch, doors and trunks and installing them in place of the old ones.
• Replacing the damaged core (plug) of the lock with a new one while maintaining the old security mechanism.

The second option is possible if you can purchase original spare parts; the Chinese-made larvae are not included in the body, and it will not be possible to fit them. Sequence of actions for replacing the ignition switch:

1. Insert the key and turn it clockwise until it stops.
2. Using a screwdriver, a knitting needle or a piece of wire of a suitable size, we recess the latch; this will allow the cylinder to come out of the body by about 5 mm. When performing this action, you should be careful so that the spring-loaded part does not “fly out” of the socket and get lost.
3. We remove the core with the secrecy mechanism from the housing with extreme care.
4. Using the described method, we disassemble the new larva.

Now it is necessary to change in the new core all the figured frames and springs that make up the ignition switch security mechanism. This can only be done if their number and external dimensions match. When performing manipulations with devices, you need to be very careful and careful. You should not completely disassemble both mechanisms and try to assemble one from two units. Experts recommend doing this:

• We remove the plate from the outermost slot of the new lock and set it aside.
• We take out the part from the seat with a similar position of the old unit.
• Now it needs to be inserted into the vacated slot of the new housing until it stops.

Warning! Any mistake when replacing the plates in the new ignition switch mechanism will make it impossible to use. If everything is done correctly, then we reassemble the unit in the reverse order. The latch is carefully pressed out with a suitable object, and the sorted larva is inserted into the body until it stops.

To ensure smooth operation of the unit, apply a small amount of silicone grease to it. After assembling the ignition switch, turn the mechanism until it stops and back several times; there should be no jams when performing this action. Now it can be installed in place and the driver will use the old key to open the doors and trunk of the Daewoo Nexia, as well as to start the engine.

The car of the Korean manufacturer is popular among car enthusiasts. Daewoo Nexia is a convenient and practical vehicle for the city. But, unfortunately, there are no ideal cars; each has its own weak points. In Nexia, this is a group of contacts in the ignition switch. It often breaks down. In the article we will look at why the contact group burns, how to repair and replace, what to do to prevent the part from burning in the future?

Eliminating the cause of burnout

It should be noted that replacing the contact group with a working one helps for a while. For high-quality repairs, it is necessary to eliminate the cause of burnout: reduce the current load on the contacts. You can strengthen the weak point of the Daewoo Nexia by installing additional relays according to the diagram:

When using two relays, the load on a group of contacts is halved

This method will help extend the service life of the contact group by more than 2 times. Anyone can improve the electrical ignition circuit of a Korean car.
