Universal Wireless Garage Keypad

The LiftMaster 877MAX wireless keypad provides keyless entry for Chamberlain, LiftMaster and Sears Craftsman garage door openers manufactured since 1993. It operates with a 9 V alkaline battery and uses rolling‑code security that generates a new access code with every use. A flip‑up cover protects the backlit buttons from rain, snow and strong sunlight.

Check Opener Learn Button Before Ordering

Verify that the existing opener has a purple, red, orange, yellow or green learn button; the keypad does not support Security+ 3.0 white‑button openers produced in 2026 or legacy DIP‑switch models. Compatible model numbers include 877MAX, 878MAX, 877LM, 377LM, 977LM and 66LM. No wiring is required for installation.

Sustained Outdoor Operation

The weather‑resistant enclosure and pre‑installed 9 V battery allow reliable daily operation through temperature swings and precipitation. Rolling‑code technology continues to prevent code‑grabbing attacks over extended use, while the backlit keys remain visible during night‑time entry. Mounting screws and step‑by‑step instructions are included for a quick DIY setup.

Questions about this item

Does the 877MAX keypad include everything needed for mounting, or must I buy screws and a battery separately?

The package ships with a pre-installed 9V alkaline battery and mounting screws, so no extra parts are required for a standard wall installation.

My opener has a yellow learn button — will the 877MAX work, or should I choose the 878MAX instead?

The 877MAX is compatible with yellow, purple, red, orange and green learn buttons on Chamberlain, LiftMaster and Sears Craftsman openers made since 1993; it does not support Security+ 3.0 white-button or DIP-switch models.

What does "over 3/4 horsepower" mean for daily use of this wireless keypad?

The rating refers to the garage door opener motor the keypad controls, not the keypad itself; the keypad simply sends a rolling-code signal to any compatible opener regardless of that motor's horsepower.
