It is possible to duplicate a standard key but not a transponder key. In contrast to the remote central locking element of a standard key which uses battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.

To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits IR energy which is picked up by a microchip inside the key. The chip responds by sending a unique code to the immobiliser of your car.
