Need some help with Homelink


Jul 1, 2018

Did a search, but didn't see any solutions - would appreciate some input.

I just had the EMMC chip in my 2015 Model S replaced under warranty. Of course when they do this, the car is wiped of several settings, including Homelink settings. Homelink has worked fine for me for several years. I went to reprogram, and noticed that you need a remote. Guess what - I couldn't find a remote! So I ordered a pair on Amazon.

I received the remotes, and they paired very easily with my "yellow button" Chamberlain opener. Now it should be easy, right?

Wrong! I've started the procedure in the car several times, and have gotten to the point where they tell you to take the remote, hold it 3" away from (and slightly to the left of) the Tesla logo on the hood, and push and hold the remote button.

No dice. Lights wont flash indicating it read the frequency. Inside the car the MCU is still looking for the remote code. I've tried this 20 times, closer to the car, further away from the car, etc. It will not see the code.

Any words of wisdom here?

If the remote opens the door, then it should functionally be the same and you should be able to use it for Homelink learning. I have aftermarket remotes for my motorcycle keychains and they were a little challenging to get to work with Homelink, but eventually they worked.

I would try varying where you point the remote at the car. Maybe rotate it on one axis or another. It sounds like witchcraft, but maybe there is something about the pattern the remote emits when sending a signal, and the car cannot read it. This is of no consequence when you're several feet away from the garage door opener receiver. You might also see if another Tesla can learn from your remote, or if you can ask to learn someone else's garage door. You could also try buying a different brand of remote if all else fails.

Try using D Mode:

To program HomeLink" (if equipped):
1. Park Model S so that the front bumper is
in front of the garage door, gate, or light
you want to program.

close during programming. Before
programming, make sure that the
device is clear of any people or

only have approximately 30 seconds to

some cases the programming process
may require multiple attempts before

Thanks all! Trying in Frunk didn't work. Tried setting mode to "D-Mode", but keep getting an error that "D-Mode was not enabled". Going to try to find the original remote and try that. I appreciate all the input.

OK - Interesting update.

I mentioned in my original post that I was trying to program with a 3rd party remote I bought through Amazon. It was easy to train the new remote and it works flawlessly to open and close the garage door. However, it was unsuccessful in programming my Model S.

I did another search for the original Chamberlain remote that came with my opener, and got lucky and found it.

Tried programming the Homelink in the car with the original remote, and it worked perfectly the very first time I tried. So if you are struggling with programming, and using a 3rd party remote, I'd recommend buying one of the original manufacturer remotes, training the new remote, and then trying the car homelink training with that remote.
