Access is granted via a programmable 4-digit PIN on a backlit keypad for visibility in low-light conditions. The slide-up protective cover shields the keypad from weather exposure. The unit mounts to any smooth surface at a minimum height of 5 ft above grade, out of the path of the moving door and within line of sight of the opener. Power is supplied by a single 9V battery.\u003c\/p\u003e\n\u003cp\u003eProgramming follows one of four methods depending on opener type: DIP switch-based openers (3-position or 2-position), Smart\/Learn button openers (yellow, white, or grey button), or Smart\/Learn button openers with a dedicated opener ID code. The correct programming method is determined by identifying the opener type before beginning setup. The 387LMC is a variant of the 387LM and is covered by the same installation manual.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal compatibility with major garage door opener brands across multiple opener types and frequencies\u003c\/li\u003e\n\u003cli\u003eProgrammable 4-digit PIN with four distinct programming methods to match opener type\u003c\/li\u003e\n\u003cli\u003eBacklit keypad for visibility in low-light conditions\u003c\/li\u003e\n\u003cli\u003eSlide-up protective cover for weather resistance\u003c\/li\u003e\n\u003cli\u003eSurface mount installation; mounts at minimum 5 ft height, within line of sight of opener\u003c\/li\u003e\n\u003cli\u003e4-digit PIN changeable by user without re-programming the opener\u003c\/li\u003e\n\u003cli\u003ePowered by one 9V battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 387LM (see also 387LMC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Universal wireless keyless entry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccess Code:\u003c\/strong\u003e 4-digit PIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e One 9V battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Surface mount, minimum 5 ft height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Opener Types:\u003c\/strong\u003e DIP switch (3-position and 2-position), Smart\/Learn button (yellow, white, grey), Smart\/Learn button with opener ID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Brands:\u003c\/strong\u003e LiftMaster, Chamberlain, Sears Craftsman, Master Mechanic, Do It, Genie, Linear, Moore-O-Matic, Stanley, Overhead Door, Wayne Dalton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e LiftMaster \/ The Chamberlain Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConclusion\u003c\/h3\u003e\n\u003cp\u003eBefore purchasing, identify your garage door opener type using the four-category reference in the installation manual to confirm compatibility and determine the correct programming method. LiftMaster products manufactured after 1993 require photo-eye safety sensors to be attached and working; if sensors are not present, the opener is not compliant with current federal safety regulations. The 387LMC shares the same installation manual and programming procedure as the 387LM.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/387lmManual.pdf?2614\" class=\"elite-button\" target=\"_blank\"\u003eDownload Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"LiftMaster","offers":[{"title":"Default Title","offer_id":20400521707574,"sku":"387LM","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/products\/Liftmaster387LM.jpg?v=1753915085","url":"https:\/\/elitegates.net\/products\/liftmaster-387lm-universal-wireless-keyless-entry","provider":"Elite Gates","version":"1.0","type":"link"}
