Indeed it does. It worked on an old Genie from the 80's at the last place I lived. You have to go inside the Genie unit to see where the code setting switches are at; there's like 8 or 12 of them and they are each set in 1 of 2 positions, up or down. They must match the switches inside the opener. This puts the opener and the unit on the same frequency so they can communicate. My advice would be to do what I did....put all the switches either in the up or down position in the unit and on the opener. It's way easier than trying to write down, "1st switch up position, 2nd switch down position," etc, and trying to match on the remote. Good luck!
