Same here.  I sold my 28l box in the unlocked position - as my dealer recommended - and the guy I sold it to got it re-coded no problem whatsoever by his (different) dealer.

I made a special tool from a large hacksaw blade that did the same as the paper clip.

It's a fiddle, but if you get a new lock you can practice on that and when you are competant at getting the lock leaf retracted it's on to the top case.


Done a few now.

Just had a word with a couple of techs.  The lock can be removed if it's in the locked or unlocked position.  Bit easier in the unlocked state though.  No need to resort to drills and hammers.

Just an update... after a good 3 hour tour of B roads my lock tumbler became un-jammed.  I was then able to turn the tumbler to the locked position.  After making a little tool from a BBQ skewer, I was able to get the tumbler out.  After understanding how it works, I don't see any way you could remove it without it being in the locked position.  My local BMW dealer told me the same and suggested that I get a locksmith to drill it out. 


The issue was that one of the springs holding the wafers in seemed to have been lost or broken.  This caused the wafer to be jammed.


Happy to finally have this resolved.

What luck!  Congratulations, and thanks for posting the update.

I am happy.  Really didn't want to try to drill it out as had read some horror stories. 


I have added some pictures of the tool I used to remove the lock tumbler with.  It is just a metal BBQ skewer that I filed the point down.
