3-Button Remote Control for Gate and Garage Doors The LiftMaster L993M is a three-button remote control compatible with LiftMaster, Chamberlain, and most Craftsman garage door openers, gate operators, and commercial door operators manufactured after 1997 with safety sensors. It operates across both Security+ 2.0 and Security+ 3.0 systems, making it the right choice for mixed-generation installations or properties where the specific opener generation is not confirmed. Openers with a yellow learn button are Security+ 2.0; openers with a white learn button are Security+ 3.0. Each of the three buttons can be programmed to a separate operator, allowing a single remote to control a combination of garage doors, gate operators, or commercial door operators from one device. Automatic frequency detection simplifies programming by eliminating the need to manually identify the opener's frequency. Operating range extends up to 1,300 ft under optimal conditions, and ultra-secure encryption protects against code interception. When paired with a compatible Security+ 2.0 or Security+ 3.0 opener, the L993M can be registered in the myQ app for remote naming, access history, and real-time notifications each time the remote is used.
