A car alarm key fob is an integral part of the security system. It is an interface through which the car owner can configure alarm operating parameters, control functions, and receive information about the condition of the car. Drivers often lose key fobs. But in case of loss, the car owner must remain in control. You must always know what to do if you lose your alarm key fob and how to restore the device. Professional installers will tell you what to do in this situation.
Where to look for the alarm unit?
Most often, control units are installed under the dashboard. But the installation location in the cabin may be different: installers are different. When you manage to find the block, you should find the Valet service button on it. More often the button is located under the instrument panel and can be carefully disguised. Sometimes the search can take a long time: you have to check every wire coming from the control unit.
"Starline"
What should I do if I lost my Starline alarm key fob? The following algorithm can be used. Open the car, turn on the ignition, hold the service button for six seconds. When the system enters service mode, the user can hear a beep. The status LED will blink more slowly. Then the ignition is turned off again.
If you have a Starline alarm PIN code, then:
- When the door is opened, the ignition is turned on and the alarm is activated.
- Within 6 seconds, enter the first digit of the PIN code using the service button. The number of presses will correspond to the password number.
- The ignition turns off and on again.
- Then another number is entered in the same way.
- Turn off and turn on the ignition again.
How to start the engine?
Owners of security systems are wondering: I lost the key fob for the alarm, is it possible to start the car?
If the security system is not equipped with an immobilizer, then there should not be any special problems with starting. Only the communicator key fob is lost, not the standard key. If the key fob is lost, following the instructions above, an emergency shutdown of the security system is performed. So, the system removes the lock and allows the engine to start.
Disabling the alarm
There are several options for disabling the car's security system.
You can turn off the alarm by pressing the “Valet” button. After this, the driver should contact a service center to solve the problem with the key fob.
You can try to disable the system by repeatedly turning the ignition key in different directions . After this, you need to quickly click on the service button the required number of times.
If you are not afraid to work with wires, follow these steps:
- find the signaling unit, which is located under the torpedo;
- take out the wires and try to start the car.
Coding can save the driver from many problems. A pre-invented code will allow you to deactivate the security system without much difficulty.
If you had the code installed, follow these steps:
- Open the car with the key, insert it into the starter and turn it over.
- Quickly press the service button the number of times indicated in the first digit of the code.
- Return the key to its original position.
Now you know what to do if the key fob for your car’s security system is broken or lost. Choose the option that suits you best and get started.
Modern car security systems are innovative, convenient and advanced technologies that make the life of a motorist easier and more comfortable. Such systems are equipped with key fobs that operate remotely. Unfortunately, such controls can fail or be lost altogether. This situation is not fatal, but it can cause a lot of problems. Every motorist should know what to do if the alarm key fob is broken or lost. This is exactly what we will talk about today.
How to restore the key fob?
Programming or linking the key fob to the alarm system is necessary in security systems that do not have a dialogue code. Binding is used to synchronize so-called “floating” code. In such solutions, one code package is used to control the main unit of the security system. The package is encrypted using a specific algorithm with unchanged basic parameters, but with a changing key.
Therefore, you have to register key fobs both when purchasing a new one, which is not initially synchronized with the main unit, and in case of problems with the standard one. Binding is also required if the standard key fob has any communication problems. It’s not for nothing that manufacturers indicate in their instructions that it is undesirable to press buttons many times outside the communication range with the machine. The key to the encryption algorithm goes further along the algorithm, although it should not change.
Reasons for failure of the key fob
If the device does not go off when you press the button on the alarm remote control, the reason should be sought not only in the key fob itself, but also in the anti-theft system. If the alarm does not respond to the key fob and the car does not open, this may be due to several types of faults.
Problems with the key fob
When the anti-theft installation refuses to see, respond and react to pressing buttons from the key fob, first of all it is necessary to diagnose the remote control itself. It is quite possible that the car alarm does not see the key fob due to a dead battery. If the remote control is equipped with a screen, check whether it responds to key presses; if there is no display, then there should be an indicator light that also lights up when a key is pressed or when the batteries are low.

The problem with the car alarm may also be related to the remote control, namely the transmitter located inside. Doing the repair yourself is problematic, so try using a spare key fob. If the system does not work correctly with it, most likely the problem is not with it.
Dead battery
A completely discharged battery can also make it impossible to operate the anti-theft system. If the battery is not completely drained, you can try to press the remote control from a closer distance to the car. Even if you manage to open the car, starting the engine will be problematic. To prevent the battery from being completely discharged, when arming the car, you need to turn off all electrical equipment.
Radio interference
It happens that radio wave impulses are jammed by various interference, and if you suddenly find yourself in such a zone, then you will not be able to either park or remove the car from the signaling system. Interference may occur near airports, military factories, and also near objects of national importance. If you really find yourself in an area of electromagnetic interference, you can check this using your phone - the interference will also affect the signal, as well as GPS communication. In this case, the only optimal solution would be to bring the remote control as close as possible to the pulse receiver.
Disassembled remote control
Loss of communication between the remote control and the unit
Malfunctions in the software can lead to loss of communication between this element and the pulse receiver, that is, the block. Only reprogramming the signal will solve this problem. To do this, you need to turn off the anti-theft system unit in emergency mode by disconnecting the wiring from it, and then resynchronize it with the remote control.
The programming procedure in this case can be done by yourself, but for this you will need a service book for the signaling. Sometimes it happens that the program is simply deleted from memory; in this case, synchronization will not produce results, since first of all you will need to restore the software. This type of repair can only be carried out by specialists.
Electronics malfunctions
Electronic malfunctions can occur even when the motor is turned off. If there is a power surge in the on-board network, the anti-theft system control unit may burn out. This is fraught not only with the need to repair or replace the unit, but also with possible wiring problems.
If the unit itself is not behaving correctly, signs of its malfunction can be identified in advance. For example, the system may turn on automatically, commands sent by the remote control will not be executed correctly, and some options may not work. If you have any doubts about the need to repair the unit, it is better to consult with specialists (the author of the video about disabling a non-working alarm is Nadezhda Bespyatykh).

Programming "Sherkhan"
A car owner has lost an alarm key fob, how to restore a new one (using the example of the Sherkhan security system).
The system can only remember three key fobs: when recording the fourth, the codes of the first and all information on them will be erased from memory. You can bind a new key fob in two ways: using a PIN code and without it.
If there is no PIN code, then the ignition is turned on and then turned off. Flashing parking lights will indicate that the system has entered programming mode. Within three seconds, press the button of the first key fob - the dimensions will blink once. Then enter the codes of the remaining key fobs.
The second method almost completely repeats the first. Within four seconds, turn the ignition key in accordance with the first digit of the PIN password. The second digit is entered in the same way. The button on the key fob is pressed for four seconds. The car will signal with its side lights. The keychain is attached and you can use it.
Choosing the right keychain
Often, problems with the car alarm control panel are solved by purchasing a new control element. Especially if the car alarm key fob was lost. It's not that simple here. You can't go to a store and buy the first item you come across. You need to know about the subtleties and rules of choice.
