Look for signs of rust or other signs the buttons have been damaged or worn. For instance the paint that conducts electricity could be missing. Then, using a Q-tip that has been dipped in alcohol, gently clean any membrane contacts that have damaged or have conductive paint missing. Avoid rubbing too hard, since this could cause damage to the conductive painting and prevent the button from firing when it is the button is pressed.

Also, be sure to check the battery connector's terminals to ensure an unattached solder connection. If this is the case, simply soldering them back in place can restore functionality to the button. The same method can be used to restore function to any loose connections inside the fob.
