Be careful not to rub too hard, because this could damage the conductive paint and block the button from firing when it is pressed.
Also, make sure to inspect the battery connector's terminals to ensure an unattached solder connection. Soldering them back in place will restore the button's functionality If this is the case. The same process can be used to restore function to any loose connections in the fob.
