LiftMaster 376LM Security+ 315MHz Keyless Entry

The LiftMaster 376LM Security+ 315MHz Keyless Entry is a wireless exterior keypad that lets you operate a compatible garage door opener using a secure personal PIN—no handheld remote required. Designed as a direct replacement or add-on keypad for Security+ 315 MHz systems, it’s a convenient upgrade for residential driveways and light commercial bays where hands-free entry is needed. The unit mounts outside the garage and communicates with the opener via LiftMaster’s rolling code Security+ technology at 315 MHz for dependable, interference-resistant performance.

This keypad programs in minutes using the opener’s PURPLE Learn button and a user-selected 4-digit PIN; typical setup is completed at the motor head by pressing Learn and entering the PIN on the keypad. It is compatible with most LiftMaster, Chamberlain, and Sears Craftsman Security+ models that operate at 315 MHz and have a purple Learn button (commonly found on units manufactured roughly mid-2000s through early 2010s). It is not compatible with Security+ 2.0 systems that use a yellow Learn button, nor with older 390 MHz Security+ systems with red/orange Learn buttons. The 376LM is powered by a 9V battery and features a weather-resistant housing with a protective flip-up cover for dependable outdoor use. For best results, mount within the opener’s radio range, avoid large metal surfaces that can reduce signal strength, and choose a unique PIN to maintain security.
