There have been a few things to get used to since I took delivery of my Model 3, but the task that has caused me hours of frustration was programming my HomeLink gate and garage door codes!

I followed the instructions on my Model 3 screen carefully MANY times, including using new the batteries in my remotes.

Of the 2 codes that I needed the car to learn from the remote, only once did the headlights flash, and in that instance the result was not successful.

I tried the method that HomeLink.com specified for the Model 3 -- which suggest multiple cycles of "press for 2 seconds and then release", versus the Model 3's instruction of continuous press.

I read a single post on TMC (found by Google) that suggested programming the remote with the frunk open -- there were no follow-up posts with other's experiences.

I used the onscreen instructions, except the frunk was open, and my remote was "aimed" at the latch slot.

Each of the two buttons/codes caused the headlights to flash -- and they worked.

I think the most important key is fresh batteries in the remotes and they tend to work right away.

Maybe it was the vintage of the gear (2004-ish).

Could it be related to the existence or not of a front plate? I have one.

But I tried multiple clickers and did replace the batteries on one of them (new, name brand CR2032's).

Extremely frustrating (multiple sessions over a few days, with no success at all for either code).

Until I opened the frunk and aimed the clicker at the slot where the latch was -- then each of the two codes (gate and garage) took first time, within seconds.

That’s really strange ... they tell you to point at the front passenger side beneath the headlight so a front plate shouldn’t matter

When I did mine, the instruction said front center iirc. (At lease am sure it did not say passenger below the headlight)

@MarkB thank you! thank you! thank you! for the suggestion. The very first time I tried to send the signal to from the remote to the car it worked, but I did not have the car outside of the garage to get the opener to learn the car. I decided to delete the setup and start fresh with fresh batteries. Over 3 separate nights I tried to redo step one and get the signal from the remote to the car without success. I felt like Clark Griswold trying to get the Christmas lights lit! Popping the FRUNK did the trick for me and don't think it really matters where you point the remote after doing that. Maybe the frunk just acts enough like a Faraday cage that it blocks the remote signal.

There may be other places to point the remote at when trying to get it to learn that doesn't require popping the frunk, but I tried point to the passenger side of the nose several times and that didn't help. Tesla really should really add some troubleshooting tips in the procedures or add some steps that make it easier. I'm sure I'm not going to be the only person to struggle setting this up.
