Don't rub too hard, as this could erode 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 in place will restore the button's functionality in the event that this is the situation. You can follow the same method to restore functionality to any other loose connection within the fob.
