Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that has become worn-out or where conductive painting is missing. Don't rub too hard, as this could erode the conductive paint, and block the button from firing when it is pressed.
Check the battery connector terminals carefully for any loose solder connections. If this is the case, connecting them back may restore functionality to the button. You can use the same procedure to restore functionality to any other loose connection in the fob.
If any of the rubber buttons on the front of the keyfob isn't working or need to be pressed very hard, the graphite disks at the back of the button could have worn out and will require replacement. This can be done by rubbing a pencil over the disks, which will bring the button back to life.
