I bought a keypad for my opener but the only way I can make it work is to eliminate all the codes from the opener and then I can program the keypad. But as soon as I program the remote, The keypad does not work. It seems like the remote is overiding the keypad code and eliminating it. I can only put in the keypad to work when there is no other codes in the opener. I need the keypad and remote to both work, not one or the other.
