Examine for indications of rust or other indications that the buttons have been worn or damaged. For instance, conductive paint may be missing. 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. Be careful not to rub too hard, as this can erode the conductive paint and block the button firing when pressed.
Check the battery connector terminals for loose solder connections. If keyed car repair near me is the case, simply soldering them back in place could restore function to the button. You can apply the same method to restore functionality to any other loose connection in the fob.
If any of the rubber buttons at the front of the keyfob isn't working or require being pressing very hard the graphite disks on the back of the button may have worn out and require replacement. This can usually be done by rubbing a pencil on the disks, which will bring the button back to life.
