The Liftmaster 373LM remote was used with Liftmaster, Chamberlain and Raynor garage door openers from 2006 to 2014. The 3-button remote is compatible with those brands of openers with a Purple Learn Button. The Learn Button can be found on the back of the operator. The 373LM features Security+ rolling code technology and works on a 315MHz frequency. If you need a 1-button remote use the 371LM 1-Button Remote.
The 373LM remote replaces the discontinued Raynor 373RGD remote
