The remaining two locations represent locked positions. One of them will be ignored as it is exactly between two whole numbers on the dial. Before the dial reaches 11, there will be three points where the dial will resist being turned anymore. The exploit involves lifting up a locked shackle with one hand while turning the combination dial counterclockwise starting at the number 0 with the other. There's a vulnerability in Master Lock branded padlocks that allows anyone to learn the combination in eight or fewer tries, a process that requires less than two minutes and a minimal amount of skill to carry out.
