I would appreciate any help I can get on this. I have tried to program my homelink with my garage door. I followed the directions to the letter and nothing happens. When I push the two outside buttons the light should come on in 20 seconds. It does not come on ever. Is there a fuse to the homelink I can checks or do I need to open up the rear view mirror and check wires. All other functions of my rear view mirror work.

Sometimes you have to press & hold the 2 outside buttons to erase all stored codes for what seems like an eternity. 20 Seconds seems like an eternity when you are programming... much longer than you feel is 20 seconds. I had to hold mine for what seemed like a minute.

Do it at night when the tiny blinking LED is easier to see. Your mirror may require more than 20 seconds. If your garage opener has rolling codes, don't forget the last 2 steps. Go to http://www.homelink.com/program.php to watch a video on programming.

My '04 was an easy learn, with my old garage opener. My 07 with the new opener with rolling codes took a few times. Once you are successfull it will all make sense.

Thanks for your help I will watch the video links and try again with the buttons.

The videos were good but still nothing. I held those buttons for a minute and the light never came on I must have a problem in there somewhere. I thought it could be a fuse or something.

I must have tried half a dozen times but I can;t program my garage door opener and it is looking pretty embarrassing at this point. I press the learn button on the garage door opener itself and then I press and hold the button I want to program. Am I missing something or could there be something wrong with the opener?

if the light does not lit up, then there is definitely something wrong with the homelink. Also please make sure the car ignition is on, because it does not work without the keys. I figured that out about 10 min in when I was the process. haha

If yours is similar to mine ...

1. Start car and leave it idling just outside the open garage door.
2. Get up on the ladder and push the "Learn" button on your garage door opener.
3. Ease off the ladder and step quickly to your car, then press and hold the mirror button you choose ... hold it a good 20 secs or so until it flashes.
4. Close the garage door using the mirror button, then open it again.

That should do it. I hope.

Just another suggestion from my personal experience.... kinda weird. My garage has a rolling code. I tried the usual steps, and nothing.

So I got one of the handheld openers linked to the garage and programmed it into the car, knowing full well that it won't work for rolling codes. Then, I did the rolling code procedure for the same button in the car, and voila. I have no possible explanation other than maybe the Homelink button needs to fail at trying to program the regular way first before doing the rolling way?

charliele729

That is correct. the failure procedure has to be perform first. After knowing and fully understanding how to do this, it took me littler 10 sec to for every car that needed to be homelink with the garage.

I think this is what's happening to me and why I could not program the homelink button after truing for 30 minutes (my background is in software development)! Out of frustration I gave up to try another time.

I have a LIft Master opener with a rolling code so are you suggesting that I should first try to get it to learn from a remote clicker and then go through the procedure for rolling codes? Something that made no sense on the manual is how it tells you to keep pressing the button you want to program TWICE No other remote I have makes you do this. I click on the learn button on the opener, long press the button on the device I want to program and it is done. I'll keep trying...

charliele729

Ok I know it is tricky, but here it is for a regular person manual lol:
1) program the homelink with the clicker on any button you choose
2) you will now notice the button will flash fast then pause, that mean it is a rolling code design.
3) click the learn button on the garage motor
4) now run to the car and hold on the same button from step 1.
5) now your done! whoa laaa!

Barry45RPM

Voila !

YES! After programming "incorrectly" using the remote clicker, the button stores the "wrong code" - e.g., when you push the button, it tries to send the wrong code based on the way the LED blinks. THEN, you do the rolling code procedure to override this "wrong code" with the rolling one.

You guys are AMAIZING! It worked!!!

Here I was wasting half an hour of my time following the instructions on the manual and feeling dumber and dumber each time... How hard can it be to program a garage door opener!

I tried the method mentioned above where you do something you know is going to fail and then you do what should have worked in the first place and that's it!

I know MB is doing this whole green initiative saving the trees and the environment and what not. Think of all they can do to save the environment if they stop printing the 500+ page manuals and instead give out a card to each owner with the inscription:

"We do not know what we are talking about. Please consult the experts at mbworld.org"

With rolling codes, its really a 2 step process:

1. Teach your specific Open/Close code to the Homelink mirror with your factory Garage Door Remote. (sort of like adding an extra key)
-Then-
2. Teach your garage door opener to accept the code now being transmitted by your mirror's transmitter to the opener head unit. (That's sort of like giving the opener headunit permission to accept the open/close code from a new source.)

...with the older non rolling code garage door openers, all you had to do was teach the open/close code to the mirror. The door opener would accept the open/close command from any properly coded opener button as the code was always the same and there was no need to synch up or give the opener permission to talk with the mirror.
