Liftmaster 877LM Wireless Keyless Entry Garage Door Keypad

Product Description

The LIFTMASTER 877LM is a wireless keyless entry keypad designed for residential garage door opener systems equipped with Security 2.0 rolling-code technology. It mounts outside the garage and allows entry via a personal access code, eliminating the need for a remote transmitter. The 877LM communicates using encrypted rolling-code signals, which change with every use to prevent code-grabbing and unauthorized access. Licensed garage door technicians and security-conscious homeowners install this unit as a primary or supplemental access point for garages and gated entry systems.

The 877LM is suited for residential applications where a permanent, weatherproof exterior keypad is needed at a garage entry point. It is compatible with LIFTMASTER garage door opener systems that support the Security 2.0 wireless protocol. It operates without hardwired connections to the opener, making it straightforward to position at any exterior garage location within wireless range of the opener unit.
