With the help of special methods, it is possible to duplicate a standard car key however, not transponder keys. Transponder chips are powered by an infrared signal, not battery power.

To activate the transponder, the ignition cylinder must be in the ON position. The ring emits IR energy which is detected by a microchip in the key. The chip responds with an unique code to the immobiliser in your car. The car's computer analyzes the code stored in its memory to the transponder's and when the two codes match it will begin the engine.

Modern cars have this system as standard. This makes it extremely difficult to hot-wire a vehicle or use a different key as a starter. The system works by analyzing the chip inside the key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU then knows that it's the right key and that the passcode hasn't been compromised.
