The LiftMaster 387LM Universal Keyless Entry is an exterior-mount, wireless garage door opener keypad that lets you open and close your door with a personal 4-digit PIN—no remote or keys required. Designed as a universal replacement or upgrade, it works with most major-brand residential openers manufactured since 1993 that use a learn button or DIP switches, including many LiftMaster, Chamberlain, and Craftsman Security+ models (315/390 MHz), Genie Intellicode and Overhead Door CodeDodger, Linear/Moore-O-Matic (318 MHz), Stanley (310 MHz), and Wayne-Dalton (372 MHz) systems. It supports common operating frequencies used across these brands (typically 310, 315, 318, 372, and 390 MHz), and features a weather-resistant, backlit keypad for reliable outdoor use and easy nighttime visibility. Power is supplied by a 9V battery.
Programming is straightforward: select the appropriate brand mode on the keypad, then pair it to the opener via the opener’s learn button to complete the setup. Once programmed, enter your PIN and press Enter to operate the door. For safety, mount the keypad out of children’s reach and only program with the door in the closed position; ensure your opener’s photo-eye reversal system is installed and working before use. Compatibility note: the 387LM is not designed for openers that use LiftMaster/Chamberlain/Craftsman Security+ 2.0 (yellow learn button). For buyers searching terms like universal garage door keypad, replacement keypad for LiftMaster/Chamberlain/Craftsman, or Genie/Overhead Door compatible wireless keypad, the 387LM offers broad multi-brand compatibility and simple exterior access control for residential applications.
