With the help of specific methods, it is possible to duplicate a standard car key however, not the transponder key. Contrary to the central locking element remote of a conventional key which uses battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.

To activate the transponder chip, the ignition cylinder must be switched to ON. The ring emits a flash of IR energy that is absorbed by the microchip in the key. The chip responds by transmitting a unique code to your car's immobiliser. The computer in the car examines the code in its memory with the transponder's code and when the two codes match, it will start the engine.

The immobiliser shuts down the engine in the event of an unauthorized key or transponder. It also stops any essential components of the vehicle from working.

This is why it's so hard to defeat.

Modern cars are fitted with this security system by default. This makes it very difficult to hot-wire the car or use a different key for starter. The system works by checking the chip in the key fob or key and transmitting a passcode to the ECU (electronic control unit). The ECU will then verify that it's the correct key and that the passcode hasn't been compromised. The system won't permit the car to start if the doesn't have the correct code, and some models will even inform the owner if someone tries to use a wrong fob or key.
