How many combinations?

[Boogs]

Having a tinker recently with some of the cars. I accidentally picked up the locking wheel nut key to my sons R56MCS and used it on my wife's F56JCW. Imagine my surprise when it fitted?

Does anyone know how many combinations mini have, because quite frankly they are feck all use if they are all the same. Might have to replace them with after market jobs.

Thanks, one almighty coincidence, perhaps I should have bought a lottery ticket.
