get 4 cheap stock lug nuts, mix you up some JB weld, heavy on the hardner, and stick the lug nut on to your locknut, let the JB weld set and presto, you can take them off, or if you know someone who can weld, have them weld you a nut onto the lock, locks will stop some people, but if they want it real bad, they just use a tow truck!
