Check for evidence of rust, or other indications that the buttons are worn or damaged. For example the paint that conducts electricity could be missing. Then, using the Q-tip, dipped in alcohol to gently clean any membrane contacts that are damaged or have conductive paint missing. Do not rub too vigorously, as this could erode the conductive paint and stop the button from firing when you press it.
Also, make sure to inspect the battery connector's terminals for any loose solder connections. If this is the case, simply connecting them back can restore function to the button. You can apply the same method to restore functionality to any other loose connection in the fob.
