The LiftMaster 878MAX Wireless Keyless Entry System provides convenient and secure garage access using a personalized PIN, eliminating the need for keys or handheld remotes. It can store up to four unique PIN codes, making it easy to provide separate access for family members or other trusted users. Rolling code technology helps protect against unauthorized entry by changing the access code with each use, while the backlit keypad provides clear visibility at night or in low-light conditions. Its weather-resistant design is built for reliable outdoor use, and installation and programming are simple. The 878MAX is compatible with LiftMaster garage door openers manufactured since 1993, with one-button-to-close functionality available on compatible models manufactured since 2006.
