Look for signs of corrosion or other signs that the buttons are worn out or damaged, like missing conductive paint. Use a Q-tip dipped into alcohol to gently clean any membrane contact that has become worn-out or where conductive painting is missing. Avoid rubbing too hard because this could damage the conductive painting and prevent the button from firing when it is the button is pressed.
Also, be sure to check the battery connector terminals for an unattached solder connection. Soldering them back in place will allow the button to function again If this is the situation. You can use the same method to restore functionality to any other loose connection within the fob.
