Look for signs of rust or other indications that the buttons have been damaged or worn. For example the paint that conducts electricity could be missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that has become worn out or where to repair car key remote conductive painting is missing. Do not rub too vigorously, as this could erode the conductive paint, and block the button from firing when pressed.

Examine the battery connector's terminals carefully for any loose solder connections. If this is the case, reconnecting them could restore functionality to the button. You can apply the same procedure to restore functionality to any other loose connection within the fob.

If any of the rubber buttons located at the front of the keyfob isn't working or need to be pressed very hard the graphite disks on the back of the button might have worn out and require replacement. This is usually done by rubbing a pencil on the disks, which will bring the button back to its original state.
