I have an Allister ARD IIA garage door opener (about 15 years old) and one of two remotes went out. It uses a Craftsman remote, which I ordered (the exact same part number as the old remote). The question now is, how do I program the remote to open the garage door? The instructions with the remote say to press the orange "smart" button but this garage door opener doesn't have a button anywhere on it. There must be someway to program the remote as I have one Craftsman remote that works. Can anyone help with this or have one of these garage door openers?
