It can be integrated into the PCM (power control module), BCM (brake control module for brake control) instrument clusters, smart junction boxes, or standalone modules.

Transponder Chip

In vehicles manufactured after 1995, a tiny electronic chip called transponder is embedded in the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop the engine from starting when another person has the same key. It works by transmitting an audio frequency signal from the key to the immobiliser system in your car.

The key that is equipped with a transponder chip can be referred to as a 'fob' or a 'smart' key due to the fact that it is more difficult to clone than a traditional mechanical key. Utilizing specific methods, it is possible to copy a conventional car key, but not the transponder key. Transponder chips are powered by an infrared signal and not battery power.

The chip responds by sending a unique code the immobiliser in your car.

If you try to start the car and the light is solid on it means that the chip in your key doesn't match the code stored in the ECU.

The system will not allow the car to start if it does not receive the correct code. Some models will even inform the owner if someone tries to use a wrong fob or key.
