Hey yall.

I applied my search-fu and came up short, so my apologies for what may be a repetitive question.

I picked up my new (to me) 2014 435i yesterday and one of the very first things I am trying to do is synch my garage door opener with the integrated module.

Following the directions seems to get results similar to what it says it should do, but still slightly different, but net results not working.

Now odd side note first: My E46 M3 had no issues and synched on first attempt and worked flawlessly. My partners 01 X5 behaves exactly like the 435, appears to wipe settings, proper solid to blinking etc for the lights to synch, but never actually talks to the opener.

I dont believe it is a rotating code opener and there is no sync/program button on the opener itself to be prepared for a new controller.

So.. I hold both outer buttons to wipe all settings.
Then hold button 1 and a working remote simultaniously until the mirror light goes from slow blink, to rapid. (rapid seems a little spazzy though) Release buttons.

Press button 1 on the mirror and it seems like it broadcasts, but nothing happens. Buttons 2 and 3 blink in the proper fashion to show not programmed. Rinse and repeat across buttons 2 and 3, all seem programmed, and nothing.

The X5 does the SAME thing and drives me crazy.

Any suggestions?

I vaguely recall having to hold the opener's remote controller right next to the opener, probably had to do with the rolling code thing. Is your opener "HomeLink" compatible? I tried helping to sync my neighbor's new X3 a couple years ago, not good...found out it was an older garage opener (25 yrs old) and did not have HomeLink. There's a video on the BMW website and possibly also on YouTube that I'm sure you already checked out.

Awesome question.. the strange variable here is it worked in my M3, but not the older X5 or newer 435i!

It could be the remote... not sure though. Doesn't help I LOATHE the main door opener as it is older, and LOUD. I want to tear it out but can't right now.

When I got my car a few months ago I also had issues making this work. I finally figured out that the 1st button under the mirror was defective. I programmed the 3rd button instead and it worked perfectly.

Thanks.. I appreciate that and will check the other buttons. They all act properly at least, when I hit full reset, all three buttons will slow blink as if they are not programmed. If I walk all three buttons through the programming, they all ACT like they are programmed but still wont talk to the opener.

I only live a couple of miles from my dealership and when I picked up my car the salesman followed me home and programmed it for me. Quickly and works like a charm with one slight exception (my previous car had homelink and the homelink worked faster and from farther away -- I used to be able to press the button when I was across the street but now I can't get it to work until I am entering my driveway). But other than that small glitch it works fine. But programming homelink and equivalent has always been a bear.

I found the process frustrating at first until I found the attached video...

Use the 2nd method - the alternating code method. Works like a charm!

I don't know--I've used HomeLink on openers that were that old, and it worked fine. In fact, it was easier because there were no rolling codes.

One thing that I found on one of my cars was that if the batteries are not strong in the opener remote, it can be difficult to initially program. Try it again with fresh batteries.

It's possible you're running afoul of a change in the RF security protocol for the opener. Happened sometime in the aughts (2005-2010'ish). I'm vague on the details but I believe Homelink changed their protocols to accommodate the new protocol, therefore not all years/models of BMW's will have the same level of compatibility.

We've also experienced similar things to what you're seeing with similar cars, since we had an '02 X5, '02 330i, '12 X5, '14 335i. We were having some work done on the garage door opener once and the repair guy installed a homelink repeater which took care of the weirdness. I also never solved weirdness with our neighborhood gated entry - that remote programmed easily with all of our cars except never would work with the F30. It would show all the right signs of having taken the program but just wouldn't work.

Anyway, Google "homelink repeater" and you'll see what I'm talking about. If you call homelink and they determine you need one, they'll send you one for free.

Homelink.. as in BMW? If a free repeater would fix this I am all for it, but unclear of who I would call.

thank you for all of the info!

The built-in garage door opener in your BMW is made by Homelink. You can call Homelink directly for help. I've never done so personally, but others have said they're pretty helpful. The instructions on the homelink website are also reportedly better than BMW's, but I've never had an issue with BMW's instructions.

so I talked with a garage door pro.. my opener was a cheap POS in late 80s/90s.. the guy was shocked it even worked at all.

So at this point I am looking to replace it regardless.

thanks yall!

Good move. Get a belt-drive opener, they're super-quiet compared to the screw and chain models.

Both times I've had an opener replaced the installer programmed my cars to work with the new opener. That's when I got the (free) homelink bridge thing. The pros made the whole programming thing look fast and easy.

I have the same car (2014 435) and was able to get mine to work on a 3-4 year old Liftmaster Security+. The order may seem backwards but I don't think it matters based on the LED feedback received from both the mirror and opener:

- On the garage door opener itself, press the program button. The LED turns on sold on mine once pressed

- Then in the car, hold down the mirror button you want to program for at least 15 seconds

- My garage door instructions say the main lights will blink once it's learned the new remote (car) but mine never did (i think because I did the process backwards). I did notice that after the last step, the program light started to blink so it is clearly seeing the car. Oddly enough, the garage door manual doesn't even mention a blinking LED

- Then in the car, I put the garage remote about 2 inches from the mirror, and then pressed and held the same mirror button and garage remote open button at the same time until the mirror LED blinked fast

- Mirror button started to work at this point and seems to work reliably

I had previously tried to program this by just doing the remote to mirror, but it didn't work and I couldn't find my garage door opener manual at the time so put it off until this weekend. Thanks OP for posting this as I was determined to get this working today

Not sure if mentioned already, but remember to press button on the Garage unit itself. You'll then have 30 secs to do the sequence on the Homelink in the car.

yeah.. this thing isn't a rolling code unit but a dinosaur Era dip switch train wreck. I have given up making it work, and looking seriously into replacing it. It is stupid loud anyway.. needs to go.

I think this is the point I wasn't doing in mine to get it to work. Will try to follow the above youtube video.

[CalCarNut]

Seems like mystery solved then. I had zero issues programming my '15GC or my '12 X3..

[Dang3r]

Darn, this worx only at ya at US, caused by frequency here all motors are not responding...bummer

[RRedline]

I just had this happen to me -- it turns out that there are 2 versions of Homelink -- Homelink V3 (HL3) and Homelink V4 (HL4).

Older HL3 garage door openers have a white antenna wire and white learn button. If you have a newer garage door opener with a yellow antenna and/or yellow learn button, you have HL4 and you need a HL4 compatible mirror or you need to buy a repeater kit from Homelink to make your HL3 mirror work with an HL4 opener.

To check your mirror, look at the FCC stamp on the back and see if it says HL3 or HL4.

[jd_perspective]

I've been living at my current place for 2 years with this car have never been able to program it. lol I'm not a moron either it just doesn't sync. Who knows!
But getting a new house I'll try again when I move in...
