With the help of specific techniques, it is feasible to copy a conventional car key but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst IR energy which is picked up by a microchip inside the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer checks the code in its memory with that from the transponder chip, and when they match the engine will be able to start.

Modern cars come with this system as standard. This makes it very difficult to hot-wire a car or utilize a different key for starter. The system works by checking the chip inside a key fob or key, and sending a passcode back to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code hasn't been compromised. The system won't allow the vehicle to start if it does not receive the correct code, and some models will even report back to the owner in the event that someone attempts to use an unapproved fob or key.
