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 system won't allow the car to begin when it doesn't receive the correct code. Some models even inform the owner when they attempt to use an unapproved fob or key.
The system isn't foolproof, however. Some thieves have been able to bypass the immobiliser by using methods like hot-wiring.
