It can be integrated into the PCM (power control module) BCM (brake control module), instrument cluster smart junction boxes or standalone modules. The system examines the code to ensure it is correct. If the code is not correct the system will disable components that are essential to the start of the car, like the starter motor or ignition.

With the help of specific techniques, it is feasible to copy a standard car key but not a transponder key. In contrast to the remote central locking element of a conventional key, which uses battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.

To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits a blast of IR energy, which is absorbed by the microchip in the key. The chip responds by sending a unique code to the immobiliser of your car. The car's computer compares the code in its memory with that from the transponder chip, and If they are compatible the engine will begin to rev.

If the immobiliser is able to detect an unauthorized transponder or key is being used it will shut down the engine and stop any of its vital components from working. The car won't move in the event that the engine is not functioning. It is easy for a criminal hot-wire it to drive away.

This system for car immobilisation is an an effective way to stop thieves, but it is also possible for it to become out of connection with the key or transponder chip. This can be due to interference or the system becoming too sensitive. If this is the case, it could be necessary to reset. To do this, disconnect the battery. After 15 minutes, reinstall the battery and restart the vehicle. This will reset the system and allow it to accept your key again.

The security light is the car key button repair immobiliser's method of letting you know that there's a problem with the system. If you try to start the car and the light stays on, it means that the chip in your key isn't compatible with the code that is stored in the ECU. This can happen if you have recently replaced the car key with another that has not been programmed to the vehicle or when you've had a damaged swapped ECU.

If this is the case, then it's time to go to a professional and have the key or the transponder chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key because of an issue with the software or an update. To test this, put your key in the ignition and turn it to ON but don't try to start the engine. Let the key stay in this position for ten minutes.

Modern cars come with this system as standard. This makes it extremely difficult to connect the car to a hot wire or use another key for starter. The system works by checking the chip inside the key fob or key fob repair near me and sending a passcode back to the ECU (electronic control unit).

The system will not allow the car to start if it does not receive the correct code, and some models will even inform the owner if someone tries to use an unapproved key or fob.

However it isn't foolproof. Some thieves have bypassed the immobiliser using methods such as 'hot wiring.' This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU to believe that the correct key or fob is being used. But, this technique is pretty risky and requires a great deal of experience to do it without electrocuting yourself. In addition, many modern car thieves have shifted to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's information and remotely control it from their phone.

Car owners are often faced with warning lights that indicate that the immobiliser is malfunctioning. This can happen for various reasons, but one of the most frequent causes is a dead or defective battery in the key fob. A simple replacement should fix this issue.
