891LM (891RGD) Liftmaster 1-Button Remote Security +2.0 Technology
Compatible with various Raynor garage door operators with a Yellow Learn Button
Liftmaster 891LM Remote is a 1-button garage door opener remote that
uses the Security + 2.0 technology so that every time you push the remote
button you know that it's secure. If you have a Raynor garage door
opener that has a Yellow Circle Learn Button (see the list of compatible
Raynor openers below) then the 891LM remote is compatible replacement remote. The 891LM
remote can be programmed to control one garage door opener.
The 891LM remote is the same as the 891RGD remote as they are both manufactured by Liftmaster/Chamberlain. The only difference is the 891RGD remote has "Raynor" printed on the remote while the 891LM remote has "Liftmaster" printed on it.
