Socket for security lug nuts Cracked

[Rapps]

Purchased car Sept, first time remove wheels. The socket for the security/locking lug nuts has begun to crack and also looks like it has stripped some as well. It still fits onto a nut but any more use and it will crack completely apart.
I've asked the previous owner if he has any manufacture info, no response yet. The only identifying information is on the security lug nut, a number. Any ideas? Thanks for the help.

Edit, yes sorry added pictures thanks for the help

Any ideas?

A. Make an assumption that it is the commom brand, McGard, take a picture of it, and email them to sell you another key.

B. Post a picture here, and maybe someone will recognize it.

C. Take it and the car down to Discount Tire, or some other good, volume tire store. Maybe they will recognize it, then email the manufacturer. Also, they have the "universal" tool to get your nuts off. They deal with lost security lug nut "keys" all the time. Then just buy a new set.

D. Take it down to Autozone and other parts stores. and see if you can match/find the manufacturer

After all the above, you might consider McGard spline drive. Not cheap, but a different style of tool than I've seen before, as well as the tool is available separately.

You can also buy a tool from Sears that removes the locks. Kind of destroys them in the process though as you hammer it on the outside of the lock. I would take em off and replace them with regular lugs. Do you really leave your car unattended in an area where someone is going to steal your wheels? They only fit on a Viper after all.

Oh, one other thing, any one can buy the tool from Sears including thieves so the locks are really a false sense of security.

The last tire to be removed is the one with this problem. Excellent ideas, working on them now, didn't want to take the car off the jack stands if I can avoid it, as I had already put it away (plate/insurance changes made) for the winter.

Update:
Tried locating the manufacture without success. Had a fellow put a brass sleeve on the socket, it was a tight fit so much so it also started to crack; it will never come off. But the threads are stripped enough that the sleeve held but the threads let it spin around.
So I mashed a socket over the lug nut and it came right off. Of coarse the future for the socket isn't bright but I got the wheel off
