Home Link intermittently working

Does anyone here have an issue with their garage home link button? Mine works intermittently. Sometimes it works only when facing the garage. Sometimes it works either facing or not facing the garage. Sometimes, it says to set it up like new, but I already set it up once. I guess it lost the signal and wants to set it up again. The home link is hit or miss, so frustrating.

 

Recently, the homelink in our Q60, Titan and new Corolla has begun to be finicky. Seems to be about the same time as 5G coming online.

Sometimes they work like they used to, sometimes I need to be right up against the garage door, sometimes I need to angle the vehicle, and sometimes opening a window helps.

Prior to this, all 3 homelink vehicles worked perfectly, the Titan being 16 years old and current house being owned for 10 years, no issues until now.

 

Mine works fine.

 

My Tundra is the only one that is finicky. My MB and Corolla works just fine. Even works a few yards away.

 

I had the same issue you are having. It turned out my garage door opener was going bad. I replaced it with a new Chamberlain about a year ago and it's worked perfectly for both my Tundra and my wife's Highlander since.

 

5G cellular frequencies are much higher than the typical garage door opener which operates between 300 and 390 MHz. Cellular starts around 700 MHz and with 5G can go almost to 30 GHz.

 

I just sold my garage door company and retired.....almost every time a remote device is working intermittently the issue is interference from an RF source. It can be a bear to pinpoint. Usual culprits are LED lightbulbs, old refrigerators, older garage door openers.

 

I did have a problem with LED light bulbs in mine and I went back to using incandescent.

You made me realize something just now, I have a somewhat new wifi router and it's just about directly above my garage door opener!

 

That could be it....had a customer a couple years ago that remodeled a bathroom directly above the garage. If the heated tile floor kicked on , the remotes would not work.

 

Cheap LED light bulbs are a notorious source of interference in the VHF radio bands where garage door openers operate. My first experience with Homelink or its predecessor was in a 2008 Highlander. Sometimes it would work 30ft from the door and sometimes it wouldn’t work right next to the door. The solution in my case was to improve the antenna on the opener (a little wire hanging down in some cases) by splicing a solid bare copper wire (center conductor out of a cable tv jumper) and running it horizontally over the ceiling. That improved things substantially.
