Find a 1/2 drive socket that barely fits on the end, pound it on hard with a big hammer, and you may be able to loosen it that way. I've done it before. If not go to the parts store, and ask for a locking lug removal tool.

 

If I had even decently nice wheels, i'd be afraid to be swinging a big hammer around them...[&:]

 

Go to your local tire shop, they should have a removal tool for em. Itll take em like 5 minutes to remove em all. Its usually $5 per lock.

i had one that no tool could get out, i ended up drilling out the stud

 

You didnt do it right. You need an impact gun to get em off. The sockets for "burning" the locks off are smooth on the inside, you put it on the gun press really hard toward the lug nut while its spinning. This heats up the socket and allows the metal to expand. After you do that for a few seconds get a hammer and pund the **** out of the socket on to the lock nut. THen put your impact gun backon the socket and vwalla off comes the lock nut.
