LiftMaster 878MAX Wireless Keyless Entry Keypad
The LiftMaster 878MAX wireless keyless entry system is used to add exterior PIN-code access to compatible LiftMaster, Chamberlain, and Craftsman garage door openers. It communicates by radio signal with supported openers and allows users to open the door without a handheld remote.
The MAX keypad family is designed for a broad range of learn-button openers, including Security+ 2.0 yellow learn button units, Security+ 315 MHz purple learn button units, Security+ 390 MHz orange/red learn button units, and older Billion Code 390 MHz green learn button units. It is not intended for older DIP switch-only receiver systems.
This uploaded row contains a part-number/title mismatch: the mfgid is 878MAX, while the visible title mentions 877MAX. Both are commonly searched wireless keypad references, but the exact product being sold should be confirmed before publishing the final product title or inventory listing.
