Examine for signs of rust or other signs the buttons have been damaged or worn out. For example, conductive paint may be missing. Use a Q-tip dipped into alcohol to gently clean any membrane contact that has worn out or where conductive painting is missing. Be careful not to rub too hard, as this can erode the conductive paint and block the button from firing when it is pressed.
Also, be sure to check the battery connector's terminals to ensure a loose solder connection. Soldering them back to their original position will allow the button to function again in the event that this is the case. The same procedure 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 need to be press very hard the graphite disks on the back of the button may have worn out and will require replacement. This can usually be done by rubbing a pencil on the disks, which will bring the button back to life.

If you're not comfortable with this, you can go to your local Oreilly or hardware store and utilize their RF frequency tester. This will let you know whether the key fob transmits an RF signal.
Programming
