Huh? My wrench can R&R a busted CV joint, or fix my gear box. How do you fix a lock that has been cut or pried open? It's a serious question I have for you. I truly don't understand why someone who has had their lock compromised by a thief would take the busted and unfixable lock to a locksmith.

EDIT: Of course I'm talking about the U-locks you mentioned earlier.
