LiftMaster855lm Homelink Repeater Kit

Some important things to realize about this product:(1) Their online marketing material is not clear, but the smaller box that looks like a remote control is *ONLY* for programming your older car's HomeLink 1.0 system. You cannot use it as an additional GDO (garage door opener) remote. However, I'm planning on keeping it in case I have to reprogram my old car due to a battery disconnect or I buy a different older model car.(2) Place the repeater (the larger box) as close to the GDO as possible. Mine is about 18" from it, and it works great. Some reviewers had complained about this, perhaps because they don't have an electrical outlet close to the GDO. But I don't understand that rationale because the GDO runs on electricity, so why not just plug the repeater into the same electrical outlet, even if you have to use a power strip?(3) The repeater works as an intermediate relay, essentially taking your old car's HomeLink transmission (v1.0 is at a lower frequency) and converting it to the higher frequency required by the HomeLink v2.0 system (which is probably what your new GDO senses). The higher frequency gives HomeLink an opportunity to offer you control over more devices within your home.(4) Use the smaller box (the thing that looks like a GDO remote) to first sense what frequency your car's built-in HomeLink 1.0 system broadcasts at. Those instructions are per YOUR vehicle and will NOT be included in this HomeLink product. If you don't have the original owner's manual, find one online or call a dealership to ask how to program a new GDO remote.(5) Follow the instructions included with this HomeLink Repeater product to sync it with your car's output. It's super simple; literally the press of two buttons within a 30-second window.(6) IMPORTANT: Straighten the purple antenna wire so that it hangs straight down as much as possible. If it is coiled, it will not sense your car's signal as well, forcing you to get drive closer to the garage to be within range. One reviewer here mentioned you could tie an 18-gauge wire to the end of the purple antenna wire with a wire nut in order to extend your range, but I did not have to do that.(7) The total install took me about 10 minutes, but that included reading the instructions, digging through a drawer, setting up a ladder to reach the electrical outlet above my GDO, and walking between my car (outside the garage) and the ladder inside my garage. :-)(8) When finished, my 2001 BMW's old HomeLink built-in NOW reaches considerably farther than what I had before. I can activate the GDO from the top of the hill, about 300 feet from the garage. It works fantabulous!This is a solid product, easy to install, and gave me more range than my old built-in HomeLink broadcasting unit in my BMW. Good luck!

The Homelink transmitter in our 2002 Jeep Grand Cherokee is not compatible with our newer opener as-is, but this little gadget fixed things right up! Happy wife, happy life!

So, I purchased a new garage door opener and it wouldn't work with my homeland in my BMW and Honda. In fact, any car 2011 or older needs this part for it to work with HomeLink. After a call to customer service I was told I needed to buy this repeater.Why do you need this? Homelink (not Chamberlain or Liftmaster) has developed a more sophisticated wireless encoding system that is being used in new vehicles. To fix this, Chamberlain and Liiftmaster developed a transceiver that recognizes the older door opener codes and translates it to version 2.0 Homelink codes. This allows older vehicles to work with Version 2.0. Seems like an easy way to add $25 to the price. Why not make it backward compatible?This does reduce the security of the coding scheme that opens and closes the doors; effectively downgrading this security from 2.0 to 1.0 version.Only issue is that the range is terrible!!!!!! I needed to pull into my driveway for it to connect and begin to open the door. With the remote that came with the door I could be 200 feet away. Effectively reducing the range from 200 to 25 feet So, I improvised.The simple fix is get a piece of 18 gauge wire, about 2 feet long and splice it into the antenna on the repeater (the white wire in the picture). After I did this, the range increased to about 100 feet. Not equlivent to the remote alone but enough to have it open as I pull in.This repeater solves this problem for all cars simply and effectively. Easy to install and setup. It works well however the range issue is inexcusable. If you can live with the remote rather than the HomeLink buttons the range much better.

Emparejado (1) con un operador Liftmaster 87504-267, me permitió mantener funcional el sistema HomeLink en mi vehículo, y evito el tener que llevar en la visera el control remoto del motor. Solo mencionar que debí mantener pulsado el botón programado en el HomeLink durante 10 segundos despues del parpadeo en las luces del motor para que lograr el puente. Lo recomiendo.

Easy to install and set up. worked like a charm to connect Homelink on two older vehicles to a brand new garage opener. The whole setup took maybe 5 minutes. And I am bad with electronics. I loved the simplicity of the whole system and how effective it is.

My lift master garage opener is 19years old and this homelink worked perfectly.

I have two liftmaster jackshaft garage door openers installed in a new house build. I have two older vehicles (2007, 2008) with the older Homelink remotes (one on the mirror and one on the visor). Both my vehicle Homelink remotes operate and are programmed in the same way.Since I had two garage door openers that would not work with my older vehicles, I had to buy two Homelink Repeater kits....or so I thought.Learn from my experience.Installation was fairly straightforward following my Liftmaster instructions, the Homelink repeater instructions, and the Homelink instructions in my vehicle owner manuals. The problems I had were that the garage door sensitivity was not that great. Sometimes the doors would open and sometimes not. When a door would not open, I would hav eto get out of my vehicle and use the keypad to open it. Very frustrating.What I learned was that the two Homelink repeaters were interfering with one another. The recommendation was to space them further apart. I had them about 6 or 7 feet from one anothre and they were still interfering. I had to unplug one of the repeaters so the other would work consistently (and quite well). One trouble shooting solution said I may have to replace the control board in my Liftmaster opener. I finally came across a helpful customer service support person from Chamberlain who said, in short, I only needed one repeater with one remote to program BOTH my garage door openers. They said if I had three garage doors, I still would only need one repeater with one remote. Sure enough, the one repeater/remote combo was all I needed. Both doors open consistently without fail.Why this isn't documented anywhere, I don't know other than the resellers are trying to sell more of these units. If some people can get multiple repeaters to work without fail, more profit for the resellers. I have had them for 6 months now so likely I can't return the one I don't need. Don't buy more than one, that is all you need unless you have garage doors that are VERY far apart and outside of the repeater range.

worked well after getting it programmed but need to follow instructions to a tee I needed heip from liftMaster
