Don't know if anyone ever had this problem, it could only happen to me. Had Ford McGard wheel locks on my Contour, went to remove fronts for brakes. First lock key cracked without breaking lock loose, then second wheel key broke entirely, deforming it so could not tell pattern. Drove around trying to find a match since card lost with the code on it. Now how to remove the freaking wheels?? I went to hardware store and bought 3/4" outside nut, which just matched OD of the lock. Glued it to end of lock with yellow 3M Superweatherstrip Adhesive. Used a Dremel with a long thin chainsaw sharpening rock. Lying down by car, used the side profile of the 3/4" nut to cut flats on the round lock to match the nut. 6 flats and 10 minutes later, used a 3/4" lug wrench to pop off the lock. Much easier than I thought, did all 4 wheels in about 45 minutes.
