Use the Q-tip, dipped in alcohol, gently clean any membrane contacts that have become worn or where conductive paint is missing. Don't rub too hard, as this could erode the conductive paint and stop the button from firing when you press it.

Check the battery connector's terminals carefully for any loose solder connections. Soldering them back in place will allow the button to function again If this is the case. You can use the same process to restore functionality to any other loose connection within the fob.
