Did both remotes ever work?

I can get them both to work now but not at the same time. I cannot say for sure that both ever worked at the same time. I think that they did when I 1st bought the house. Then I programmed the built in button in my new truck and didn't need the other one so set it aside for a couple years. Now the truck with the built in button is gone and I need the 2cnd remote again.

There is a problem where a remote will quit rolling the code and will cause the problem you have. You can usually tell which one it is because it is the one that will not work with the keypad and the other one will. But----you say your keypad is also not working. Try programming the keypad again and make sure you press and immediately release the learn button on the motor unit.
