It is possible to duplicate a traditional key, but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a flash of IR energy that is detected by the microchip inside the key. The chip then sends an unique code to the immobiliser in your car. The car's computer compared the code in its memory with the one here from the transponder chip and when they match the engine will be able to start.

The security light is the car immobiliser's way of telling you that there is a problem with the system. If the light is on when you attempt to start your car, it is a sign that the code in the ECU is not compatible with the chip on the key. This can occur if your car key has been replaced with an alternative key that is not compatible with the vehicle, or when an ECU was not swapped correctly.

Some models will even inform the owner in the event that someone attempts to use an incorrect fob or key.
