It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the computer of the car matches the signal sent by the key the immobiliser will then be disarmed and the engine will be able to start.
The key with the transponder can also be 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 traditional key, but not a transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits a burst IR energy that is received by a microchip inside the key. The chip responds with a unique code to the immobiliser of your car. The car's computer compared the code in its memory with the one from the transponder chip and if they match the engine will be able to start.
If the immobiliser detects that an unauthorised transponder, key or other device is being used, it will disable the engine and prevent any of its essential components from functioning.

The security light is a way of warning you of the presence of a problem. If you try to start the car but the light stays on it indicates that the chip in your key doesn't match the code that is stored in the ECU.

Modern cars come with this system as standard. This makes it very difficult to wire a car or utilize a different key for starter. The system works by checking the chip in the key fob or key and sending a passcode to the ECU (electronic control unit). The ECU recognizes that it is the correct key and hasn't be compromised code. The system will not allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner when they attempt to use an unapproved fob or key.
