Examine for indications of rust or other indications that the buttons are worn or damaged. For instance there could be conductive paint missing. Then, using a Q-tip dipped in rubbing alcohol, gently clean any membrane contacts that have become damaged or have conductive paint missing. Avoid rubbing too hard, since this could cause damage to the conductive paint and stop the button from firing when it is pressed.

Examine the battery connector's terminals for loose solder connections. Soldering them back into place will restore the button's functionality in the event that this is the case. You can follow the same process to restore functionality to any other loose connection inside the fob.
