    I believe one of my little ones misplaced a comfort access key fob somewhere in the house or garage. It is not in the car. I still have the second FOB that works well. It is for a 2016 328d. I'm hoping it is a known RFID signal that the FOB emits and I could use a RFID receiver to try and...

    Hi guys, I'm new to this forum, it looks great! My problem is this: Bought a 520D Touring 2008. One key works and it seems it was the only one ever used. The battery is on the way out but still works if you get closer to the roof spoiler. The other "new" key worked in the ignition but didn't...

    Hey! My comfort access is not working for more than a year now and I thought that the battery would need to be changed. I did that, and no luck. The CA does not work on door handles and on the trunk. There is a second lock button on the trunk which stopped working too. It happened all of a...
  7. Car Navigation, Audio & Electronics
    So, I have had the car for a couple of months and I really like it. It's a much better drive than I anticipated it would be going in, considering that it is an "e". I have gotten very comfortable with the car and its capabilities and I have integrated my driving habits into it quite well. One...

    Hello all this is my first post so.. My g20 already have devices to run a "keyless go" system in which car recognizes if the key fob is inside of the car or not. I thought If I could add some exterior antenna's I could activate unlock-lock by approach-leave functionality of comfort Access...

    Both of my comfort access fob’s suddenly stopped working. Recently I found that they worked to open the car when standing at the trunk and pointing it at the real taillight at the top of the trunk door. This now doesn’t seem to be working either. It’s definitely not the batteries, I replaced...

    I’m hoping someone can figure this out because I’m stumped. I have a 2019 330 x drive with comfort access. For the year I’ve had it, I haven’t had issues with my comfort access until about a month ago when my fob started to get a low battery warning in my dash. About a week ago, the function...

    So my '16 F10 does not have Comfort Access. I would like to have it at least on the front doors and kick open the trunk. Time to search... First I do internet and see it cost about $700~$900. OK, fair enough. Next is the DIY route but I am not that talented in that field to take apart my car...

    Hi, sorry for my English, I try my best to express the problem understandable. I replaced a PDC ECU in a 118i E87 from 2006 (May). There was water in the box for the ECUs. So we disconnected the ECU for comfort access to dry everything. Now, the comfort access (passive go) is not working any...
