This replacement garage door remote is built for openers with a purple learn button, operating on 315 MHz with rolling code security to help protect your home's access. It works as an aftermarket match for a wide range of LiftMaster, Chamberlain, and Sears Craftsman models, including LiftMaster 370LM, 371LM, 372LM, and 373LM, Chamberlain 950D, 953D, and 956D, and Craftsman 139.53753. The remote uses a single button for straightforward one-touch operation, and its compact, mini ellipse shape is sized to fit easily on a keychain, in a pocket, or in a backpack for everyday carry. A metal-reinforced keychain frame adds extra solidity compared to an all-plastic remote, giving it a sturdier feel for daily use on the go.
