It is possible to duplicate a traditional key, but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.

To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst of IR energy, which is picked up by the microchip within the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer examines the code in its memory to the one on the transponder and when the two codes match it will start the engine.
