Examine for signs of rust or other indications that buttons are worn out or damaged, such as missing conductive paint. Use a Q-tip that has been dipped in 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 it is pressed.
Examine the battery connector’s terminals for loose solder connections. Soldering them back in place will restore the button’s functionality If this is the situation. You can follow the same method 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 functioning or require to be pressing very hard the graphite disks at the back of the button may have worn out and will require replacement. This is usually done by rubbing a pencil across the disks. This should bring the button back to life.
