This chip transmits a code to the immobilizer unit of the car that can be integrated into the PCM, BCM, instrument cluster smart junction box, or standalone module. The system then verifies the code to ensure it is correct. If it is not then the system will disable parts that are essential to start the vehicle, like the starter motor or ignition. This makes the car difficult to start if you don't have the right key.

A small electronic chip, referred to as transponder, is incorporated inside the head portion of your car keys. The technology was introduced in cars made after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when someone else has the same key. It functions by sending the radio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be disarmed and the engine will start.

The key with a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. It is possible to duplicate a standard key, but not a transponder key. Transponder chips are powered by an infrared signal not battery power.

To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits IR energy that is picked up by a microchip inside the key. The chip responds with a unique code to the immobiliser in your car. The computer in the car examines the code in its memory with the transponder's code and if the two codes match it will begin the engine.

Modern cars come with this security system as standard. This makes it really hard to hot-wire the car or use another key for starter. The system works by analyzing the chip inside the key fob or key, and sending a passcode back to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system won't allow the car to start when it doesn't receive the correct code. Some models even notify the owner if they try to use an unapproved fob or key.


The system isn't completely 100% secure, however. Some thieves have managed to bypass the immobiliser by using techniques like 'hot-wiring.'
