Utilizing specific techniques, it is possible to copy a standard car key, but not the transponder key. Transponder chips are powered by an infrared signal not battery power.

The chip then responds with an individual code to the immobiliser inside your car. The car's computer compared the code in its memory with the one from the transponder chip, and when they match the engine will begin to rev.

The security light is a way of warning you of an issue. If the light is illuminated and you attempt to start your car, it means that the code that is stored in the ECU does not match the chip on the key. This can occur if your car key was replaced with an alternative key that is not compatible with the vehicle, or when an ECU has been swapped incorrectly.

The ECU is then able to determine that it's the right key and that the passcode isn't compromised. The system will not allow the car to start if it does not receive the correct code. Certain models will even notify the owner if they try to use an incorrect fob or key.
However the system isn't foolproof. Some thieves have managed to bypass the immobiliser with techniques such as 'hot-wiring.'
