I had the same issue as you before new remotes with a program can run $70 plus.
but if you open up one of the remotes there is a metallic pad under each button that "completes a circuit" when pressed and most likely its worn out.
To test this take a rubber button that works and put it over the circuit board on the area that's not working and try Hope that makes sense. It should make it work.
So you could go on ebay and get the exact same remote and just put the new buttons in with fresh contact pads and save some money. (If your broke like me) If not
go to the.......stealership
