Do not rub too vigorously as this can damage the conductive paint, and block the button from firing when you press it.

Check the battery connector terminals for loose solder connections. If this is the case, simply reconnecting them can restore function to the button. You can apply the same process to restore functionality to any other loose connection within the fob.
