Look for signs of corrosion or other indications that the buttons are worn out or damaged, like missing the conductive paint. Utilizing the Q-tip, dipped in alcohol, gently clean any membrane contacts that have worn or where conductive paint is missing. Don’t rub too hard as this can damage the conductive paint and prevent the button from firing when it is pressed.
Check the battery connector terminals for loose solder connections. Soldering them back into place will restore the button’s functionality if this is the situation. You can apply the same process to restore functionality to any other loose connection in the fob.
If, for instance, any of the buttons made of rubber on the front of the key fob aren’t working or require a long press to function it is likely the graphite disks that are on the back of the button are deteriorating and require replacement. This is usually done by rubbing a pencil across the disks, which will bring the button back to its original state.
