Liftmaster 855lm Chamberlain OEM Homelink Compatibility Bridge

I have 2 cars with older Homelink systems built in that will not speak to my modern garage door heads. So I bought this product and voila now both cars open the garage doors. What's nice is that I can set up each garage door for any button. So both cars can open both doors individually. The training is no different than how you set up your garage door opener now: use the provided new remote to train the car, press the train button on the garage door head and press the button in the car you just trained. The head learns the code magically via this product and the garage door opens.

I could not get my garage door to sync with the home link in the car. (I am not new to home link and have used it successfully many times with numerous garage door openers.) This compatibility bridge solved the connectivity problem. It acts as a "go between" that receives the signal from the car's home link, and sends it to the receiver on the door opener. For lack of a better analogy, the home link in the car could not "talk" directly to the door opener without this device to "translate" the signal. It was easy to install (just plug it in), sync the units and you are done.

It’s annoying that I need to add this extra item to make the garage work, but it works. So I’ll just be happy. We had a 2022 Camry that had an accident. So we went with a 2023 Lexus and no matter what we tried. We could never get the garage door to open. Which was annoying as both cars are new, both cars are Toyota. After being annoying with the remotes for awhile I finally decided. $35. Just try it. And within 3 minutes. Homelink now works with our car. Which is more than fantastic. I’m not sure how rolling codes and such work, don’t care. We have a 5 year old garage opener and a 1 year old car. Should work. Doesn’t. But this was a simple fix.

no issues with the device, and was straight forward for compatibility with my car

Basically, it is worthless. I bought it, because I read that it would allow older garage door remotes to work with a newer Chamberlain garage door opener. It doesn't. It is supposed to allow older cars equipped with homelink to work with the new Chamberlain. It doesn't. I've wasted probably 18 hours of my life on this piece of crap. Ironically, it only took a few hours to install the new opener. The Chamberlain opener I bought functions fine, but it sucks that you have to buy a new keypad and none of the universal remotes I purchased less than a year ago work with the new Chamberlain opener. If you buy a new Chamberlain opener, none of your old remotes can be trained to operate it. If you buy this bridge hoping it will make the Chamberlain opener backward compatible with the homelink buttons in your vehicle or your older handheld remotes, you will end up frustrated and disappointed.
