Faulty Receiver Module
If your key fob has stopped working after replacing the battery but it didn't function, or stopped working in a sudden manner your receiver module might have experienced a malfunction. The receiver module is responsible for absorbing the radio frequency signals sent by your remote key fob and converting them into electrical commands which are then processed by other modules within the car.
