Review on 🚪 LiftMaster 891LM, Black - 1 Button Remote Control for Garage Door Opener by Tim Thuss

Received this item as a Christmas gift for use with the Liftmaster Security+ garage door opener. After countless attempts to program it, I hired someone to help me program it. No success. I called 800+ to find out why this remote isn't programmable. I was told my opener has a red/orange learn button and no yellow learn button so I had the wrong remote and needed the 971lm not the one I had. When I wanted to return the item I was 4 days past the return date. I didn't find anything in the description of this article that would address what color of the 'Training' button you need for compatibility. Buyer warning!
