The LiftMaster 877LM Security+ 2.0 Keyless Entry is a wireless outdoor keypad that lets you open and close a compatible garage door opener using a secure personal PIN—no remote or key needed. Designed for LiftMaster, Chamberlain, and most Craftsman openers that use Security+ 2.0 technology and have a Yellow Learn button (typically 2011 and newer), this replacement keypad is ideal for residential applications and upgrades. It features Security+ 2.0 encrypted rolling-code transmission to help prevent code grabbing, a weather‑resistant flip‑up cover, and backlit keys for easy nighttime use. Powered by a 9V battery, the unit mounts outside the garage and requires no wiring.
Programming is quick through the opener’s Learn button: press Learn on the head unit, enter your 4‑digit PIN on the 877LM, and press Enter to sync. A temporary PIN can be set for guests or service providers, and the keypad supports standard keypad lockout after repeated incorrect attempts. For best results, verify the opener’s Yellow Learn button and Security+ 2.0 branding, and follow manufacturer instructions to test safety reversal after installation. Typical use cases include replacing a lost or worn keypad, adding keyless access alongside remotes, or enabling PIN entry for family members on compatible LiftMaster, Chamberlain, and Craftsman Security+ 2.0 garage door openers.
