The LiftMaster 365LM / 371LM Security+ 315MHz Plug‑in Receiver Two Remote Kit is an add‑on radio control solution that lets you upgrade or replace the radio system on many garage door openers and gate operators. The 365LM single‑channel plug‑in receiver listens on LiftMaster Security+ 315MHz and provides a momentary dry‑contact output to the operator’s wall‑button or radio terminals, so it can enable remote control on most brands that accept a simple push‑button input. The included pair of 371LM one‑button remotes use LiftMaster’s rolling‑code Security+ technology at 315MHz for enhanced signal security and are directly compatible with LiftMaster/Chamberlain/Craftsman openers with a purple Learn button, or with other brands when this receiver is installed.
Designed for straightforward installation, the 365LM mounts near the operator, plugs into a standard outlet via its included power supply, and wires with two leads to the control input on the door or gate system. Programming is simple: press the receiver’s Learn button and then the remote button to store the code. This kit operates exclusively on LiftMaster Security+ 315MHz and is not compatible with Security+ 2.0 (yellow Learn button), older 390MHz-only systems, or dip‑switch transmitters. Typical applications include residential garage doors and light commercial doors or gates where a reliable replacement or upgrade radio is needed. For safe operation, ensure required entrapment protection devices remain installed and functional, mount the receiver in a dry indoor location away from moving parts, and follow the manufacturer’s installation and programming instructions.
