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

The chip responds by sending a unique code the immobiliser in your car. The car's computer analyzes the code stored in its memory to the transponder's code and when the two codes match it will begin the engine.

Certain models will even notify the owner if they try to use an incorrect fob or key.
