Lost lug key, how do I get a new one?

[1BAD89]

I had one strip out on me,and I had the cobra R's on there, and you couldn't get the socket on there far enough, plus the locking lug nuts are usually chromed and it's a lil harder to hammer the socket on there it wouldn't stay, ESPECIALLY if you have cobras. I tried EVERYTHING, and I mean eveything, took it to tire shops, I took it everywhere, I finally had to weld a socket+extension on there, and after a very long time I finally got it of. You can probaly go to autozone, pep boys, etc, and they will hve another kit, and one of them will probaly have your key in it.
