LiftMaster 83LM Remote Billion Code 390MHz

The LiftMaster 83LM Remote Billion Code 390MHz is a three-button garage door and gate opener transmitter designed for older LiftMaster, Chamberlain, and Sears Craftsman systems that use the 390 MHz Billion Code rolling code technology. Ideal as a replacement remote or an additional transmitter, it can operate up to three compatible doors, gates, or receivers, making it a practical choice for residential or light commercial applications where multiple access points need control.

This 3-channel remote works exclusively with operators and external receivers featuring the green Learn button associated with LiftMaster/Chamberlain/Craftsman Billion Code systems. It is not compatible with Security+ (red/orange or purple Learn button), Security+ 2.0/MyQ (yellow Learn button), or older dip-switch remotes. Programming is quick via the opener’s Learn button: press and release the green Learn button on the opener or receiver, then press the desired button on the 83LM until the indicator confirms pairing, following the manufacturer’s instructions. Operating frequency is 390 MHz Billion Code, providing rolling-code security for compatible systems.
