Using special techniques, it is possible to copy a standard car key, but not transponder keys. Transponder chips are powered by an infrared signal not battery power.

The chip then responds with an unique code to the immobiliser of your car. The car remote key fob repair's computer compares the code stored in its memory with the one from the transponder chip and if they match, the engine will start.
