Receiver and Remote Bundle, Lift Master Universal 850LM + 811LM

I still have 1980s vintage Sears Craftsman garage door openers in my garage. Stray radio frequencies from passing cars can sometimes open the doors, but the openers have a "security switch" that can disable the remote function. I keep this switch permanently on and instead have been using an add-on Skylink remote system connected to the wall mounted buttons that allows me to transmit remote signals to the opener with more secure rolling code frequencies. This has been a great way to avoid having to replace the openers entirely, but the Skylink remotes have very weak range and the Skylink system is not compatible with the built-in Homelink remote transmitters in my newer Honda cars. So my next plan was to have the Homelink buttons communicate with my home automation system, which could then open the garage doors through a z-wave signal to the Go Control garage controllers I had recently installed on the openers. However, getting Homelink to talk to my Vera, or any other z-wave network for that matter, requires installing a now-discontinued third party device and a small amount of coding, which according to some blog posts, sometimes works and sometimes doesn't. This Lift Master 850LM device replaces the Skylink system on my openers and lets me connect securely using rolling codes with the Homelink buttons in my cars. The range is also a lot better. It has 3 channels so I can set up both of my garage doors on a single device. The wiring is very straightforward but the pairing with Homelink is a little complicated. You need to have a remote (I bought the cheapest Lift Master 811LM model) to pair with the 850LM which you then use to pair with the Homelink buttons in your car. There are detailed directions on this pairing procedure that you can Google. It's not as simple as the pairing of the remote to the 850LM, but involves a number of button sequences including the learn button on the 850LM. In the end, everything works perfectly and I'm very happy.

Simple to program and works flawlessly! Signal strength is amazing! I can open and close my garage door from over 50 yards away while in the house. Over 100 yards range outside.

I was having issues with garage door remotes with a local military base. I had almost no reception range with the craftsman garage door opener. I used another alternative for a while, but those too were interfered with slightly. This unit is basically the only solution without replacing my craftsman garage door opener with a whole new unit. (I even replace circuit boards in the craftsman but it would never full increase the range). I installed this unit and attached it to the inside garage button with a short wire. I then used standard cable coax and ran the antenna to just outside the garage door at the top. I now have a long range with the remotes and with my HomeLink in my newer cars (does not work with older car, so just use the remotes). I replaced the keypad and now not only does it work better but is safer with the two stage (yellow button) remote operation.

Sometimes it works

Work great, directions sink, to complicated, good thing I’m a electrician

Finally I can open my garage door from the distance and with a first try!

Dead on arrival. Completely dead out of the box. I verified proper power multiple ways: Within the published spec (12 VAC from a LiftMaster/AccessMaster opener accessory output) Voltage confirmed with a multimeter at the receiver terminals Correct AC/DC input terminals used (per labeling) Power source confirmed working with other accessories Despite verified power: No LEDs ever light No relay click No response when pressing or holding the channel buttons No response when attempting to program a remote This unit should show some sign of life when powered, even without a programmed remote, and it does not. This appears to be DOA. Wiring, voltage, and setup were all confirmed correct.

easy hook up. was pleased with ease of installation. after trying other products that failed to work this was my last-ditch effort, and it worked!
