I recently purchased a house that has a Craftsman garage door opener. It has a key pad outside, a wall switch inside, and two remotes (one left with the house and one new one). Following the instructions in the manual, I reset the unit by holding the red button. After reseting I am only able to program either the remotes (both) or the outside key pad, but not both. They both work since whichever I program first after resetting will work but it won't let me program the other one after the first. Anyone have this before or anyone know what is wrong.

Thanks
