Examine for indications of rust or other indications that the buttons are worn or damaged. For example there could be conductive paint missing. Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that has worn out or has conductive paint missing. Don't rub too hard in order to damage the conductive paint and prevent the button from firing when you press it.
Also, be sure to check the battery connector's terminals to ensure an unattached solder connection. Soldering them back into place can restore the button's functionality If this is the case. The same method can be used to restore function to any other loose connections in the fob.
Finally, if any of the buttons made of rubber that are on the front of the key fob aren't working or require a difficult press to function, it is likely that the graphite disks at the back of the button are wearing down and require replacement. You can usually do this by rubbing a pen across the disks. This should bring the button to life.
