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

The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compares the code stored in its memory to the one from the transponder chip, and when they match the engine will be able to start.
