Wheel locks - problem

[MacCool]

My 2011 came with dealer-installed wheel locks (not at my request). Unfortunately, somewhere between that installation and me taking possession (transported from another dealer out-of-state), the unlocking key was lost. I have no way to change a tire myself. We have already established that a flat tire will result in a flatbed transport at their expense.

As it turns out, however, getting a replacement keyed socket isn't easy and so far it has befuddled the Nissan parts guy. We identified which of the 8 sockets it is in the dealer master kit, but as far as we can tell there are no identifying numbers or codes by which he can order it.

I don't really care that much about locking lug nuts, but I did pay for them. The parts guy has been trying to convince me to just ditch the locks, but he's not too keen on paying me the $51 that they added to the invoice.

Any suggestions on an expeditious way of getting this missing-wheel-lock-key problem resolved?
