LiftMaster 370LM Mini Security+ 315MHz Remote

The LiftMaster 370LM Mini Security+ 315MHz Remote is a compact, single-button keychain transmitter designed for convenient control of a single garage door opener or compatible gate operator. It uses LiftMaster’s Security+ rolling code technology to transmit a new code with every press, helping reduce the risk of code grabbing. Ideal as a replacement remote or spare, the 370LM is engineered for quick access on the go and pairs seamlessly with operators that use the 315 MHz Security+ platform.

This remote is compatible with LiftMaster, Chamberlain, and many Craftsman openers and external receivers that feature a purple Learn button, indicating Security+ at 315 MHz. It is not compatible with Security+ 2.0 systems (yellow Learn button) or older 390 MHz Security+ models (red/orange Learn button). Programming is simple: press and release the opener’s purple Learn button, then press the remote’s button until the opener light flashes or clicks to confirm. The 370LM runs on a replaceable lithium coin-cell and is suitable for residential garage doors and compatible community or light commercial gates using 315 MHz Security+ receivers. For safe operation, always ensure working photoelectric sensors are installed and keep remotes out of reach of children.
