LiftMaster 878MAX Wireless Keypad Replaces 877MAX 877LM 377LM 977LM

Enjoy secure, keyless entry to your home with the LiftMaster 878MAX Universal Wireless Garage Door Keypad. Designed for LiftMaster, Chamberlain, and Sears Craftsman garage door openers and gate operators manufactured between January 1993 and late 2025 featuring Yellow, Purple, Red, Orange, or Green learn buttons, this multi-frequency keypad provides convenient access without carrying a remote control or key.

The 878MAX is the ideal solution if you need to control up to 3 separate openers across different generations—such as a Security+ 2.0 myQ opener alongside an older Security+ gate operator—all from a single outdoor keypad.

• IMPORTANT COMPATIBILITY NOTICE: This keypad WILL NOT WORK with newer Security+ 3.0 garage door openers featuring a WHITE Learn Button (introduced in late 2025). If your opener has a White learn button, you must use the LiftMaster L979S keypad instead.
