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

The chip then responds with an individual code to the immobiliser of your car. The car's computer checks the code in its memory to the one from the transponder chip and when they match, the engine will start.
