Look for evidence of rust, or other indications that the buttons have been worn or damaged. For instance the paint that conducts electricity could be missing. Use a Q-tip that has been dipped in alcohol to gently clean any membrane contact that is damaged or where conductive painting is missing. Don't rub too hard, as this could erode the conductive paint and stop the button from firing when it is pressed.

Also, carefully check the battery connector terminals for an unattached solder connection. If this is the case, simply soldering them back in place could bring back function to the button. You can apply the same procedure to restore functionality to any other loose connection inside the fob.
