Use a Q-tip dipped into rubbing alcohol to gently clean any membrane contact that has damaged or has conductive paint missing. Don't rub too hard as this can damage the conductive paint, and block the button from firing when pressed.
Check the battery connector's terminals for loose solder connections. If this is the case, simply reconnecting them could restore functionality to the button. The same method can be used to restore function to any other loose connections inside the fob.
Finally, if any of the buttons made of rubber on the front of the key fob stop working or require a difficult press to function it is likely the graphite disks on the back of the button are deteriorating and require replacement.
