The LiftMaster 877MAX Security+ 2.0 Wireless Keyless Entry is a universal, exterior-mounted garage door opener keypad designed for secure, PIN-based access without a remote or key. Ideal as a replacement or upgrade, it uses rolling-code Security+ 2.0 technology to send a new code with every press, helping prevent unauthorized entry. The weather‑resistant, flip‑up cover protects an illuminated keypad for easy night use, and a temporary PIN feature lets you grant short-term access to guests or service providers. Powered by a 9V battery, the 877MAX programs in minutes using the opener’s Learn button—no wiring required—making it a dependable solution for residential garages and many LiftMaster-equipped gates.
This wireless keypad offers broad compatibility across LiftMaster, Chamberlain, and most Craftsman openers manufactured since 1993, including models with yellow, purple, red/orange, or green Learn buttons. It supports Security+ 2.0 as well as earlier Security+ and Billion Code systems, operating on tri-band 310/315/390 MHz frequencies to reduce interference and improve range. Typical use involves mounting near the garage door, setting a personal PIN, and following the Learn-button sequence on the opener head; a temporary PIN can be added and cleared as needed. For safety, test the opener’s photoelectric sensors and reversal system after installation and whenever reprogramming. This universal wireless keyless entry is a practical, SEO-friendly choice for buyers searching for a LiftMaster 877MAX keypad, Security+ 2.0 keypad replacement, or a compatible upgrade for multi-frequency garage door openers.
