Using special techniques, it is feasible to duplicate a standard car key, but not transponder keys. In contrast to the remote central locking element of a conventional key which is powered by batteries, a transponder chip powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is received by a microchip in the key. The chip responds by sending a unique code the immobiliser of your car. The computer in the car examines the code in its memory with the transponder's and If the two codes are identical, it will start the engine.

If the immobiliser is able to detect an unauthorized transponder or key is being used it will shut down the engine and block any of its essential components from functioning.

To do this, disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the key system to ensure that it is ready to accept keys once more.

The security light is the car immobiliser's way of telling you that there is an issue with the system. If the light is on when you attempt to start your vehicle, it indicates that the code that is stored in the ECU does not match the chip on the key. This can happen in the event that your car's key has been replaced by a new one that is not programmed for the vehicle, or when an ECU was swapped in a wrong manner.

Modern cars have this system as standard. This makes it extremely difficult to connect the car to a hot wire or use a different key as a starter. The system works by analyzing the chip in a key fob or key, and sending a passcode back to the ECU (electronic control unit). The ECU is aware that it's the right key and that there hasn't been a compromise in the code. The system won't allow the vehicle to start if it does not receive the correct code. Some models will even inform the owner in the event that someone attempts to use an unapproved fob or key.
