The key fob battery is used to power the remote locking and opening systems. However, it does not supply power to the immobiliser. The immobiliser is powered by a transponder in the fob, key or instrument cluster. This chip transmits a code to the immobilizer unit of the car which can be integrated into the PCM, BCM or instrument cluster, smart junction box or standalone module. The system then checks the code to ensure it is correct. If the code isn't correct, the system disables components that are crucial to starting the car, such as the ignition motor or starter motor.

Its purpose is to prevent the engine from starting when someone else has the same key. It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the car's computer matches the signal sent by the key, the immobiliser will be deactivated and the engine will be able to start.

The key that has the transponder chip can be referred to as"fob" or a smart key because it is much more difficult to clone than a traditional mechanical key. Using repair car key near me , it is possible to copy a standard car key but not transponder keys. Contrary to the central locking element remote of a standard key that relies on battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.

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

If the system is unable to detect a digital serial number from the chip in your key, it will disable the engine immobiliser to prevent the car from starting.

The car immobiliser is an excellent method of deterring thieves, however it can sometimes be out of in sync. This can be caused by interference or the system being too sensitive.

The security light is the car immobiliser's method of letting you know that there is an issue with the system. If you try to start the car but the light is solid on it means that the chip in your key isn't compatible with the code that is stored in the ECU.

The ECU is aware that it's the right key and that there hasn't be compromised code. The system won't allow the car to begin in the event that it does not receive the correct code. Some models even inform the owner when they attempt to use an unapproved fob or key.
