Ok - 'nother update on this
went searching for the locking nut key - I have the bag with the 4 replaced nuts in..........but no key !! - now I haven't taken it out, so ergo.......I have NO locking nut key !!!!
Holy sh!t batman - 12 months without a key !!
I have the code, so hopefully the dealer can get a replacement ? (at his cost, because I NEVER had it)
stupid me for not seeing this mind
