ThanksI got an old Kryptonite open by using your method to figure out the last 2 digits were 73 (False openings had me stuck on 84). I was about to start going through all 100 digits to figure out the first 2, but then I realized it was probably a birthday from '73. Sure enough, when I put in 19, the lock opened right away. I think everyone trying to crack a 4 digit lock should start with 19-- just to make sure and then get to work after if that does not start the code. You might get lucky!
