Mr. Puzzle took more than two hours to unlock the lock, the rest did not take him that long. He kept on pressing the broken key in deeper trying to unlock with the prongs. Then he states the orientation of the lock was what helped him unlock it. If you play his video in slow motion when he unlocks it play close attention to how deep the prong is inserted. Especially at 14:00 min into the video he is able to rotate it while having the incorrect orientation. If you go to 3:51min mark in this video here you will here LPL saying that with this lock the key is not stopped on the tip of the key it is stopped on the bow (which have been cut off), the real time waster was the proper depth of the key.
