I decided to repaint my door handles & locks today. I glass beaded everything to get the old paint off, primed & painted the locks & handles, reassembled everything, & now I can't turn the key in the locks. I thought there might be some glass beads in them, so I took them off & blew them out with compressed air, same thing. I sprayed the hell out of them with Liquid Wrench (which stripped off the paint I just applied hours earlier), same thing. I picked at the wafers with a screwdriver to make sure they moved & weren't painted fast, same thing. The key goes all the way in, but won't turn at all. What the hell did I do to them? Can I repair them or must I take them to a locksmith?
