With the help of specific techniques, it is feasible to copy a standard car key but not transponder keys. Unlike the remote central locking element of a standard key which uses battery power the transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits a blast of IR energy that is detected by the microchip inside the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compared the code in its memory with that from the transponder chip and if they match, the engine will start.
If the immobiliser detects an unauthorized transponder or key is in use, it will disable the engine and prevent any of its vital components from working.

The ECU is aware that it's the right key and that there hasn't be compromised code. The system will not allow the car to start if it does not receive the correct code, and some models will even inform the owner if someone tries to use a wrong fob or key.
