Using specific methods, it is possible to duplicate a standard car key but not the transponder key. Unlike the central locking element remote of a conventional key which uses battery power, a transponder chip is powered by an 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 turned on. The ring emits a flash of IR energy, which is absorbed by the microchip within the key. The chip responds by sending a unique code to the immobiliser in your car.

Modern cars are fitted with this security system in the standard configuration. This makes it difficult to hot-wire a car or use a different key as a starter. The system operates by sending a passcode from the key fob to the ECU. The ECU then knows that it's the right key and that the code hasn't been compromised. The system won't allow the vehicle to start if it does not receive the correct code, and some models will even report back to the owner if someone tries to use an incorrect fob or key.

The system isn't completely 100% secure, however. Some thieves have managed to bypass the immobiliser with techniques like 'hot-wiring.'
