It is possible to duplicate a conventional key, but not a transponder key. Unlike the remote central locking element of a standard key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder, the ignition cylinder must be in the ON position. The ring emits a blast of IR energy which is detected by the microchip within the key. The chip then responds with a unique code to the immobiliser inside your car.
