The Liftmaster 877MAX Keypad provides convenience and security with its rolling code 390Mhz design.

Combined with the digital code set by the user, this rolling code provides superior security. Additionally, the 976LM provides the means of protecting the confidential code by allowing a setting for a temporary code for visiting friends, delivery personnel, etc.
Moreover, the single button close function is a convenient means of closing the gate. The backlit keys also make operation easy at night or in other instances of low lighting. The Liftmaster Keypad is simple to mount, program, and use. Installation is completely wireless so there are no clumsy cords or burying of wire.
The Liftmaster 877MAX wireless keypad will work in replacement for the Liftmaster 976LM and the Liftmaster 977LM.
