With the help of special techniques, it is possible to copy a conventional car key however, not the transponder key. Transponder chips are powered by an infrared signal, not battery power.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy, which is picked up by the microchip within the key. 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 with that from the transponder chip, and If they are compatible, the engine will start.

If the light is on and you try to start your vehicle, it indicates that the code in the ECU is not compatible with the chip on the key.

The system won't permit the vehicle to start if it doesn't have the correct code, and some models will even inform the owner if someone tries to use an unapproved fob or key.
