The chip transmits a code from the key or fob to the immobilizer module of the car, which can be integrated into the PCM (power control module) BCM (brake control module), instrument clusters, smart junction boxes, or standalone modules. The system then validates the code to make sure it is correct. If it is not it is, the system will shut down parts that are essential to start the vehicle, like the ignition or starter motor.

It functions by sending the radio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer is in line with the signal sent from the key, it will deactivate the immobiliser and allow the engine to begin.

The key that has the transponder chip is sometimes called"fob" or a 'smart' key due to the fact that it is more difficult to copy than a conventional mechanical key. Using special techniques, it is feasible to copy a standard car key, but not the transponder key. In contrast to the central locking element remote of a conventional key that relies on battery power, a transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is picked up by a microchip inside the key. The chip responds by sending a unique code to your car's immobiliser. The car's computer checks the code stored in its memory with the one from the transponder chip and when they match, the engine will start.

If the immobiliser detects that an unauthorised transponder or local key is in use it will shut down the engine and stop any of its vital components from working. The car won't move when the engine isn't working. It would be easy for a criminal to hot-wire it to drive away.

If this is the case, it may need to be reset. To do this, simply disconnect the battery. After 15 minutes, reinstall the battery and restart the car. This will reset the key system so that it is ready to accept keys once more.

The security light is an immobiliser's method of alerting you to the presence of a problem. If you attempt to start the car and the light stays on, it means that the chip inside your key doesn't match the code stored in the ECU. This can occur when your car's key has been replaced by an alternative key that is not compatible with the vehicle, or if an ECU was not swapped correctly.

If this is the case you should take your transponder or key chip to a professional to have them correctly programmed for the vehicle you are driving.

Modern cars come with this system as standard. This makes it very difficult to connect the mobile car key repair near me to a hot wire or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the right key and that the code hasn't been compromised. The system will not allow the car to begin if it does not receive the correct code. Some models even inform the owner if they attempt to use an incorrect fob or key.

However it isn't completely secure. Certain thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wire in a vehicle in order to cause a malfunction in the ECU. This method is risky and requires extensive experience to avoid electrocuting oneself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to steal a car's information and remotely manage it.

Car owners often see warning lights that indicate the immobiliser has gone haywire. This could be due to many reasons, but the most common one is a faulty battery in the keyfob. This problem can be fixed by a simple replacement.

If this isn't working, the transponder chip might be faulty or mismatched with the ECU. This is more complicated to determine and fix because it requires a specialist locksmith for local cars or a dealership. However, a car immobiliser may also be damaged due to water ingress or even physically being pulled away from the fob or key.
