If your key fob has stopped working after replacing the battery, but it didn't help, or if it stopped working completely out of the blue, then your receiver module might have developed an issue. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob, and convert them into electrical signals that are then used by other modules in your car.

If the clips are corroded, or broken, you will require replacement in order for the remote control to work. Make sure that the replacement batteries have the same size, voltage and specifications as the original one.
