Top box

[Bobos578]

Looking for some help guys, BMW top box wont lock at all. Tried lubricating it but still wont work. All other functions work fine. Has anyone else had the same issue and what did you do to resolve it?

Does the key move to attach the top box to the rack? Can you remove the key?

yes I can insert the key and take the box off it just won't turn to the left to lock!!

I had the opposite problem. I put my overnight gear in the box, locked it, and when I went to open it, the key wouldn't unlock the case. Fortunately I was away for only one night.

When I got home I dismantled the case and examined it to see what the problem was. It turned out to be interference between the case and the slides that unlock the case's lid.  I filed a few of the parts so they moved more freely and it works perfectly now.

I can't remember if I needed to remove the tumbler to open it, but I do have some photos (below) of how this is done if any one needs to know. You can make a release tool from a paper clip, and insert it into the hole above the tumbler. Push down and pull the tumbler out.
