Can you only program one item no matter which one you try first? If this is so I can't imagine it being anything other than your logic board.

Could you possibly be erasing the memory by holding the smart/learn button in too long after each attempt to program. Try this programming procedure. Press and hold the button on your remote while you press and immediately release the smart/learn button. Then release the button on the remote.

i changed the code on my keypad when i moved into my new house, i have three remote controls, they were all working
when i moved in, now none of them are working, ichanged the batteries on all three, do i have to reprogam the remote after i changed the code, and if so how? i have craftsman unit,the remotes have three button each on them
