Model 950D is a 1-button visor garage door opener remote compatible with Liftmaster, Chamberlain, Sears Craftsman, and Genie garage door openers manufactured from 2005 and later. Features 315 MHz frequency with Enhanced Radio Technology (ERT) and over 100 billion rolling codes for security. Programmable using the purple LED light on compatible openers. Controls one garage door—opens, closes, and toggles opener lights on and off. Includes visor clip and key ring attachment options. Note: This remote operates at 315 MHz. Military Land Mobile Radio (LMR) equipment near certain bases operates at 390 MHz, which may cause interference with garage door openers in that frequency band. If interference occurs, consider the Liftmaster 355LM Conversion Kit, which operates on an alternate frequency.
