The receiver compares the information with the permitted signals stored on the key fob and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.

After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car keys reprogramming, even if they look similar.
