Have an unusual issue with the Homelink system on my 2023 RX. Successfully connected button #1 to the one garage door opener. On to programming button #3 with the second garage door opener, using the same exact procedure as the first, the system seems to make a connection, as indicated by the flashing light on the door opener. Then, nothing. The Homelink cannot operate the door to open or close, even though the system indicated it was connected by the flashing light. Any ideas, did I miss something? Thanks in advance.

 

I had a problem connecting button 3 to a 2nd home. I couldn't get it to work so a phoned Homelink and they walked me through the programming. Not sure what I was doing wrong but they talked me through it.

 

Homelink can be a nightmare. Procedure is different for different cars and varies based in the age and model of your garage door openers. Calling Homelink as suggested is a very good idea.
