Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it didn't work, or if it stopped working in a sudden manner the receiver module could have developed a problem. The receiver module is responsible for receiving the radio frequency signals transmitted by the remote key fob and transform them into electrical commands that are then acted on by other modules in the car.
