Ah ok thanks. Yeah the module was probably my next step to replace if I didn't find more info from other diagnostics. Although I already took it out to inspect visually and it looked OK.

Hi All,
Posting a comment because I've spent hours reading and still not sure what to do. I have a 2013 BMW M3 comp and the comfort access to unlock and lock the doors stopped working. It does start with the key in my pocket though. I just replaced one of my keyfobs and had both programmed and synced with comfort access. So both keys have new batteries and are programmed. The fobs both unlock and lock the doors from the keyfob itself. Is the fuse my next check? Who has a diagram and location? Thanks all |

I already tried replacing my driver door handle with a new one, but then it acted very weird. First time I installed a working used one one, it seemed to work once then died. Then sometimes it would work, sometimes not, or then it would lock until it timed out. And one day it just gave up and never came back to life. At this point I think it has to be the module 100%. I've been procrastinating it but just saw your reply and it's recent. If we don't have anything else once ~ spring arrives I will probably order a new one and replace it and report back. Last time I inspected my module I could not find any water issues so it's why I'm on the fence if that's it. |

Yes, I can open the trunk with the key in pocket.
What module with styrofoam are you referring to? Where is it located? I'd like to inspect mine. |

I purchased a comfort access passive go module. It should arrive early next week. I will let you know how it turns out. From my reads, it is plug and play- no coding needed.

Swapped the module and still no success. Even the start feature of comfort access stopped working when swapping which made me think these have to be programmed.
Again, at a loss. Thinking about changing the front and rear antenna and trying to find out exactly how to locate the front antenna under the ashtray/ side carpet. |

Just checked the fuse and its good. Since it starts with comfort access, I didnt think the fuse would be bad but double checked- thanks.
The reason i think it could be the antennas is because the range for the key fob is really bad, in terms of unlocking and locking. I mean like 10-15 feet away max. Also, if the key is in my pocket when starting, sometimes i need to move my leg closer to the wheel if it to recognize and start via comfort access. Thoughts? |

Also, right after starting the car with comfort access, i get a warning that the key is not in the car for the first 5-10 seconds after start.. makes me think this is an antenna issue. My car is stock, no tints or anything.

When i replaced the new comfort access module, I lost the features of comfort access that did work for me(eg. starting the car). Yes, it does appear it will need coding.

Ah ok got it. Personally, I would suspect the coding first and just default code it and see. If it still acts odd then and you can't comfort start or comfort trunk, especially if it shows up the icon for no key connection, could be antennas.

If REAL OEM, looks like the module was used on 8 different models so could be the coding for jdauti. |

I mean that same vehicle can use diff module depending on its options etc. that’s why you have to make sure the part number matches your existing module number.

Yeah but even the one you got that matches the REALOEM part number is still used in 8 different models. It's the coding that will determine which options to use and turn on and etc. But if for example the used module you got was from a E9X specifically (Well I see you have 1 series actually) I would assume it is almost plug and play without coding.

I'm in the same boat. I'm a new owner of the car and realized that both comfort access door handles do not work. I mean how likely is that they both failed?
I can start the car and also open the trunk with key in my pocket. I will check the fuses. I also replaced the batt of my key fob but same thing. |

Well I finally bought a used comfort access module and tried it out after coding it.... no success. My car works the exact same way as before, keyless start and keyless trunk unlock works but my door handles not responsive.
I wonder though if my handles are dead now and getting a new handle might work. To recap, when I first try to troubleshoot I checked all fuses and they checked out. Then I bought a used ebay handle and at first, CA seemed to work but then idk what triggered it the handle would always unlock/lock the car repeatedly until it timed out when I was in range, without even touching the handle. Did this for about a week before the handle stopped working completely. I then got another replacement handle thinking handle was just bad, same exact behavior. Maybe with the module now it a new handle would work tho hmmm... I don't like doing the parts cannon method but tbh no idea where to start with diagnosing something like this. |

Actually, have a new update here. Before giving up, I had installed the repalcement eBay handle I had (The one that randomly locked/unlocked and then stopped working). I had to pull out the car out of the garage so I did that and then I just touched the lock portion of the handle for fun and by magic it worked! I then unlocked the door, locked it again, I kept going at it for a good 30 seconds and nothing was buggy. All worked as expected, I was so ecstatic. I then decided to plug back my original handle to check that one but zero behavior with it. That said as I was plugging the eBay handle back, I could hear the system be screwy like it was before. But instead of randomly locking/unlocking the door and spamming it, I could just hear the door locks try to unlock over and over. But the moment I locked it with the handle ridges, it locked and didn't bug out when I was near so fingers crossed. And yes before someone asks, I did test the eBay handle as well before making my previous post and at first it didn't work right away when it's plugged in.
I'll report back. So funny, I had just placed a new order for a handle on eBay before I pulled the car out. Going to have to cancel that for now lol. |

A week later and everything is still working great. I think I can mark this as resolved for sure now and hopefully this helps anyone with same symptoms.
