It depends upon the nuts, of course. Years ago, I bought a Ford Ranger that had lock lugs but no key. I knew a kid that had been a hoodlum when he was younger. He gave me the solution that worked for me.

I bought a Craftsman 6pt ½ drive socket that just barely didn't fit on the lock lug (in my case, he even gave me the size, I think it was 13/16, but I can't remember for sure). You then hammer the socket onto the lug nut and use a breaker bar to take it off. You're probably going to need 4 sockets because once you get the socket on the nut, you're not going to get it off.
