Be very careful whichever route u go!! My mate has cracked a bit of his locking nut key and in turn began rounding off the nut whilst it was on, ended up taking it to 2 local companies that are famous for being able to remove them with ease!! Both companies failed and this resulted in the wheel it self being drilled and then had to be repaired with a new piece of alloy!! Check pics for the result!! Not nice!!
