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

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

If the light is on and you attempt to start your vehicle, it indicates that the code in the ECU is not compatible with the chip inside the key.

The system won't allow the car to start when it doesn't receive the correct code. Certain models will even notify the owner if they attempt to use an incorrect fob or key.

However the system isn't foolproof. Some thieves have managed to get around the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used.
