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

It's tough to beat.

Modern cars come with this security system as standard. This makes it really hard to hot-wire the car or use a different key as a starter. The system works by sending a passcode from the key fob to the ECU. The ECU knows it's the correct key and hasn't been a compromise in the code. The system won't allow the vehicle to start if it does not receive the correct code. Some models will even report back to the owner if someone tries to use an incorrect key or fob.
