With the help of special methods, it is possible to copy a standard car key, but not a transponder key. In contrast to the remote central locking element of a standard key which uses battery power the transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy which is detected by the microchip within the key. The chip responds by sending a unique code to your car's immobiliser.
