It is possible to duplicate a traditional key but not a transponder one. In contrast to the central locking element remote of a standard key which is powered by batteries, a transponder chip powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy, which is absorbed by the microchip inside the key. The chip responds by sending a unique code your car's immobiliser. The computer in the car examines the code in its memory with the one on the transponder and if the two codes match, it will start the engine.
