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

The chip then sends an unique code to the immobiliser in your car. The car's computer analyzes the code stored in its memory with the transponder's code and when the two codes match it will begin the engine.

Some models even inform the owner if they try to use a wrong fob or key.

However, the system is not foolproof. Some thieves have been able to bypass the immobiliser using techniques like 'hot-wiring'.
