I have two craftsman model 41A4315-7D. They have worked perfectly for the five years I've been in my house. Today the wireless remotes and the keypad stopped working. One keypad works sometimes. The remote in the garage works fine. Tried to find the answer doing a search, but nothing seemed to work. I have a green and amber sensor on both doors and they seem to be solid in color indicting they are pointed correctly. When I punch in the keypads they just flash. Any help
