Use the Q-tip, dipped in rubbing alcohol, gently clean any membrane contacts that have damaged or where conductive paint is missing. Be careful not to rub too hard, as this can erode the conductive paint and stop the button from firing when it is it is pressed.

Also, carefully check the battery connector terminals for an unattached solder connection. Soldering them back to their original position can restore the button's functionality in the event that this is the case.
