It works by sending an audio signal from the key to your immobiliser. If the code stored in the car's computer matches that signal transmitted by the key, it will disarm the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip is sometimes called"fob" or a "smart" key because it is much more difficult to clone than a conventional 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 switched to ON. The ring emits a burst of IR energy which is picked up by the microchip in the key. The chip responds by sending a unique code the immobiliser of your car. The car's computer compares the code in its memory with the one from the transponder chip and If they are compatible, the engine will start.
If the immobiliser detects that here an unauthorised transponder, key or other device is being used it will shut down the engine and block the essential components from working.

The ECU is aware that it's the right key and hasn't been a compromise in the 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 if they try to use an incorrect fob or key.
The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser by using techniques like 'hot-wiring'.
