It is possible to duplicate a standard key but not a transponder one. Contrary to the central locking element remote of a standard key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder must be turned on. The ring emits a burst of IR energy which is detected by the microchip inside the key. The chip responds by sending a unique code to your car's immobiliser. The car's computer checks the code stored in its memory to the one from the transponder chip, and when they match, the engine will start.
The immobiliser will shut down the engine when it detects an unauthorised key or transponder. It will also prevent any essential components of the car from functioning.

If the light is on and you attempt to start your car, it means that the code in the ECU is not compatible with the chip in the key.

The system works by checking the chip in a key fob or key and transmitting a passcode to the ECU (electronic control unit).

The system won't permit the vehicle to start if it does not receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect fob or key.
