The Stinger 390LMPB1V is a one-button visor-mount replacement remote transmitter designed specifically for LiftMaster, Chamberlain, and Sears Craftsman garage door openers that use the 390 MHz Billion Code rolling-code technology. If your opener’s receiver has a green Learn button, this remote is designed to be compatible. It provides simple, reliable operation for opening and closing residential garage doors and compatible external receivers that support LiftMaster Billion Code, making it an ideal replacement or spare for legacy systems.
Operating at 390 MHz with rolling-code security, the 390LMPB1V helps prevent code grabbing by changing its code each time the button is pressed. Setup is straightforward: press the green Learn button on the opener or receiver, then press the remote’s button to complete programming; the opener’s light typically flashes to confirm. This model is not compatible with Security+ 315 MHz (purple Learn button), Security+ 390 MHz (red/orange Learn button), Security+ 2.0/Yellow Learn button systems, or fixed DIP-switch openers. It’s intended for residential applications where a Billion Code, green Learn-button LiftMaster-family system is in use, providing a dependable, easy-to-program replacement remote for everyday operation.
