The key that is equipped with a transponder chip can be referred to as a 'fob' or a 'smart' key due to the fact that it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a traditional key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy which is detected by a microchip in the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compares the code in its memory with the one from the transponder chip and if they match the engine will be able to start.
