Review on 🔑 LiftMaster 877LM Wireless Keyless Entry - Works with 2015 to Present - Yellow Learn Button - Grey by Bruce Garner

We have four Liftmaster openers - 2 on the upper ceilings of the attached garage and 2 on the upper ceilings of the barn. This single opener can control all four with different PINs. Just perfect. The device is supplied ready for installation with a 9 volt battery. My only complaint is that the screws that come with it aren't, and in fact should be, stainless steel since these units are going to be installed outdoors. However, I did have stainless screws on hand. For that reason I would give it 4.5 stars, but Revain doesn't have half a star. I think it took me 15 minutes after opening the box to program all 4 openers. The radio range is surprisingly good! I have installed the device on the frame of my single overhead garage door and the signal operates the doors on the barn pole with no problem. I would estimate the straight line distance between the device and the farthest of these openers to be 65 feet. I was happy with this as I thought I would find I needed two of these and glad I was wrong!
