Check for evidence of rust, or other signs the buttons are damaged or worn out. For instance there could be conductive paint missing. Use a Q-tip dipped into rubbing alcohol to gently clean any membrane contact that has damaged or where conductive paint is missing. Do not rub too vigorously, as this could erode the conductive paint and prevent the button from firing when you press it.
Examine the battery connector's terminals for loose solder connections. Soldering them back to their original position will restore the button's functionality in the event that this is the case. The same method can be used to restore functionality to any other loose connections inside the fob.
If any of the rubber buttons at the front of the keyfob isn't working or require being pressed extremely hard the graphite disks on the back of the button could have worn out and will need to replaced. This can be done by rubbing a pencil across the disks. This should bring the button back to life.

Circuitry
The circuit board inside the remote control could be dirty, regardless of whether the buttons on the key fob work or not. A very thorough inspection is usually enough to fix this issue.
