Sigh - Dennis, it was the nut that was damaged not the key. I assume that the OP has long since had it fixed so why dredge it up again.
I really font get what yous are all bickering about?? 1st it says key damaged then its key is lost and now your argueing about the nuts being damaged? Has Dennis fone something to offend people that I have missed?
Then if you have a few hours spare, click on his name and this will allow you to see all his posts. After a few minutes I think you will see where it is all going.
Keeps us all amused, he does......
Hometune, you should have gone to Specsavers. In line 1 of the OP it clearly says KEY.
the moral of this story is "Try to avoid having locking wheel nuts"
