Garage Door Opener Range Issue
We have a new 2021 GLE 450 and love it. No issues so far (although we haven't used a full tank of gas yet), except the range on the garage door opener. We have two gates before getting to the garage door. Using the built-in opener for the gates, the range seems fine. But when we use the opener for the garage door, we have to pull the front of the car very close to the door before it will activate. These are not rolling code systems, they are the old pin type. Our other two cars that have built-in openers do not have this range issue, although neither of them are as good as the handheld remotes. No LED bulb in the opener. The garage door is hurricane-rated, so it is pretty thick steel, but every other opener seems to have decent range except for the new GLE. Any thoughts? First world problem I know having to wait a few more seconds for the door to open.

Both of my Mercedes GLE openers have great range. Our Audi not quite as good of range but OK with 1& 2 but 3 is very short that I use for a gate code. I have to be so close to the gate it barely clears when opening.
My point is that you probably have a bad opener, but the door might be a factor. If it were me I would start by clearing the codes by holding 1 & 3 down until it flashes yellow (as I recall) and then program it again. My new GLE 53 was hard to program and it quit working after 4 days. I cleared it and did it agin & all is well. Next I would try number 2 & then take it to the Dealer to ask for a replacement. Since the Dealer can’t test it I would record the tests with your phone.

I haven’t used the MB garage openers in years on any of my MBs. For me they continuously dropped codes. I just found it much easier to just use the door manufacturers remote and clip it to the visor.
Good luck

Thanks, will try this. It would help me know whether the door is contributing. I also need to see if I can upgrade the antenna on the receiver.

Interesting....My 450 worked for 18 months-no problem. Another thing that can cause these to malfunction is the inside garage door opener itself. If my memory is right there is only the ability to store 10 codes. If you have two remotes and an external keypad you used 3. Now program a few cars and it’s easy to hit that limit of 10. Adding the 11th one might take but drop later. I had that happen a few years ago and had to clear the memory on my inside garage door opener and start over. Next I had to clear the Homelink in my cars and reprogram them to the opener again.

I think it’s my car that has a weak signal on #3 because the gate opens from a distance with our Mercedes or a handheld opener. Is there a chance that your inside opener has been programmed for 10 devices over the years? See my previous post.

I really think that there is only one transmitter in the HomeLink device in the vehicle and that it simply transmits a different code for each opener. The button selects the appropriate code. That would be the simplest way to implement things. Three independent transmitters increase costs. Anyone know for sure?

I just flunked garage door openers on my new Mercedes because mine dropped the door code again for the second time this AM. The manual refers to a final step of hitting the pairing button on the garage unit that I didn’t do. I’ve always been able to bypass that step by pressing the button in the car 2 times. BACnMercedes I feel your pain😢

I soldered a piece of wire to the antenna and have it sticking outside in the soffit. Not the best but at least it will open before i’m on drive way.
Fyi: You should zip tie the quick release because thieves can gain access to emergency rope with coat hanger.

Many garage door receivers have a 'security' mechanism to only work for extremely short distance (usually just within inside a garage) if you cloned the signal to another device. On the garage door receiver, there should be a couple of buttons you need to press before linking the new device to make it authorized. See the door receiver manual for your model, it should be pretty straightforward.
I had a similar issue with my last new car.

Hmmmm I was going to point out to replace the battery on the original remote. I had this issue way back when with different HomeLink'ed cars, and it was resolved by replacing the battery. But seems like you had a different issue.

The range is better with the garage door open, so that has something to do with it. The gate receiver antennas are out in the open. I have the acoustic package, which has a radiation shield in the glass. Two small areas of the windshield are left open for things like toll passes. One is just to the right of the rear view mirror. I put a stick-on toll pass that is about 2 X 3 in that spot. I'm wondering if that is impeding the garage transmitter signal, and the heavy steel door compounds the problem. The openers are the old pin style, not the rolling code type, so the code is fixed. At some point I will investigate improving the antenna inside the garage.

If anyone tells her that I blame her, I’ll deny it.

Since you have an "old" style opener control you might consider one of these: https://www.liftmaster.com/850lm-uni...y-2-0/p/G850LM. It is a rolling code three channel receiver that can be purchased for around $50-60. You can place the receiver close to the front of your garage and run small wire to the terminals that your wall buttons connect to. There are other versions out there also.

Thanks, I will look into that, but part of the issue is that the opener also needs to be operable using the building's ProxKey system. This is one of those fob-based systems that allows access based on certain configurations. For example, to get in the building, make the elevator go to your floor, open/close the garage door. There are seven garages in our building. Maintenance has a for that opens the three of them that have air conditioning units shared by other garages so that when the AC service company comes they get access to all at once. Not sure how this would tie in. When I get more time, I think I'm going to try to move the toll pass that I suspect is part of the problem.

If I remember right, MB also provides a service to come out and pair your garage opener to your vehicle. As you service manager about it. I remember having difficulty pairing the Mrs. E 350 to the door opener and my Service advisor said they have a service that can come out to my home...
In the end I ended up Clearing the codes and reprogramming
for each vehicle. on my 2020 GLE it was easier.
