The 375UT-3button is the compatible replacement for the Genie GU4TG2-R, offering universal 3-button control for garage doors and gates from LiftMaster, Chamberlain, Genie, Craftsman, Linear, and Wayne Dalton models from 1983 onward. It supports both Security+ and Security+2.0 code technology with multi-frequency compatibility (300MHz, 310MHz, 315MHz, 318MHz, 390MHz, and more), and works with both rolling code and DIP switch programming methods. The compact key fob design includes a visor clip and keychain attachment for flexible carrying options, with an LED light to assist programming. All three buttons can be paired to garage doors using learn button programming, though only one button can be programmed to DIP switch-equipped openers.
