891LM Liftmaster 1-Button Garage Door Opener Remote Security +2.0 Technology
Compatible with various Liftmaster, Chamberlain, Sears & Raynor garage door operators
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 Liftmaster, Chamberlain, Sears or 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. The 891LM
remote can be programmed to control one garage door opener.
