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