If the code stored in the car's computer matches the signal sent by the key, the immobiliser will be disarmed and the engine will be able to start.
The key that has a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. Utilizing special techniques, it is feasible to copy a conventional car key but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits IR energy that is picked up by a microchip in the key. The chip then responds with an individual code to the immobiliser of your car. The car's computer checks the code stored in its memory to the one from the transponder chip, and If they are compatible the engine will be able to start.
