heres how the lock picking works, its really quite simple, hope it helps someone: start by hitting tumbler one, then move the tumb. height to 0/5, hit solve lock. if the number one is green do the same to two, if blue then 0/5 is correct for either 2, 3 or 4. if red then move up to 1/5, if its blue then 1/5 is correct for one of the other three. green means correct for that one. use this to complete the lock
