Remote keyless entry and key problem

I have a 2011 E92 with 24,000 miles. Ever since I got the car there was intermittent problems with the comfort keyless entry, trunk openning function but this was very rare. Over the last month or so it has become very common for the key to not work, it won't open the doors or trunk, remote start won't work, and for a while all of my presets went missing. I also noticed that when I put the car in reverse the right mirror doesn't go down anymore. I changes the battery on the key and it only got worse. Is this a problem with the car or the key? Anyone else with these issues?

Hrm, coincidentally. Our second key is doing this as well. Weird intermittent problems with keyless entry and you have to insert the key to start the vehicle...

It's all under warranty still, but not really wanting to make the trek to the dealer...

I have the same issues off and on. I was also having issues with receiving messages from BMW assist and google maps. Then the electronics went dead (restraints, electronic fault, transmission, dampers, etc). Took it in for emergency repairs and they replaced the junction box behind the glove box and everything worked for a month or two. Now back to intermittent comfort access and BMW assist failures. I noticed the pre-sets get erased if you take out the physical key so you may want to check that.

I do not have such issues with my remote access. The only issue that I am experiencing from time to time is that I need to open (or close) the car a few times. One funny thing I noticed - if the car is standing for long time (like a week) comfort access is not working. I need to press button on remote to open the car.

For the right rear mirror to go down you need to have the button for adjusting mirror position on right mirror. If it is on the left (driver mirror) then passenger mirror is not going down in reverse.

+1 on the mirror thing.

I haven't had many issues with the doors, but I've been having several problems with the trunk not opening. Replaced the battery in both remotes, didn't fix it. Mine is a '11 e92 w/33k. Interested to see what others have to say, subscribed.

I believe that the comfort access trunk and doors are trying to prevent thieves/robbers from getting in your car/trunk while you are getting into or out of your car.

If you use the key fob button that unlocks the trunk it should work.

Other suggestions: Pick up some spare batteries for the key fob. If your stop/start feature also isn't working you may need to replace the car battery due to low charge.

This is the first thought that popped into my head.

This car doesn't have a traditional alternator set up. Really, the only time this car charges is when you're essentially off the accelerator (from what I understand, please correct me if I'm missing something or portraying it incorrectly)

I also notice that sometimes the truk does not open. In such cases I unlock the doors and then the trunk opens immediately. Go figure...

This is true when the battery is fully charged. If new charging is needed then alternator is connected all the time.

Anyone think it's more of a keyfob issue if one key works perfectly fine and the other key essentially acts like a "valet" key?

Probably an obvious question, but if I am under warranty, this keyfob issue should be covered, right?

I would think it would be covered. BMW even replaced my battery in the key fob free of charge!!

If it was happening to both keys, I would expect it to be the battery in the car. But if it only happens to one key fob...then I don't understand.

I have a very hard time opening the trunk when the car is locked with comfort access. Now I just unlock the car and then go and pop the trunk.

Thanks for the response. Yeah, it's such a weird issue. I called the dealer and they said bring it in for them to check out. They said it's definitely covered under warranty.
