I went to swap my wheels today. I have dealer fitted BBS alloys with a locking nut in each wheel. When I went to remove the back wheel the nuts were pretty stiff but did come loose, but when I got to the locking nut the key popped out and now refuses to stayin and turn the nut. so one wheel is now stuck and the key appears to be damaged.
My local Volvo dealer tells me the key is unique to this set of nuts (not sure if this is BS) so not I have stuck nuts and no means of releasing them.

Any suggestions??
