878RGX / 877MGX Raynor Keypads
The 878RGX and 877MGX are the same wireless keypad under two Raynor numbers. They use the same radio as the LiftMaster 878MAX. They work with Raynor, LiftMaster, Chamberlain, and Craftsman openers made since January 1993 that have a green, red / orange, purple, or yellow Learn button. A current keypad for red / orange, purple, yellow, and white Learn is the L979M.
