Faulty Receiver Module If your key fob has stopped working after replacing the battery, but it didn't function, or stopped working suddenly, your receiver module could have experienced a malfunction.

Electronic chip that is malfunctioning The key fob is equipped with an electronic chip that sends a signal to the receiver module every time the key is used.
