Ah but mines came with a MacGuard locking wheel nut and I would assume that RoyE's one is the same. About time too! I used to always buy new locking wheel nuts when I had the bog standard ones. Saying that BMW don't supply a code for the locking wheel nut so I'm not so sure if it's a generic one or not.
I know when I had my Type R Honda supplied MacGuard, gave you the box they had been supplied in and the code in case you lost it.
