Abstract: A device and method to sort high security lock pins to characterize their length, wedge direction, and slot position comprises a lock pin decoding body containing lock pin cavities that receive high security lock pins and orient them in a uniform way by fitting a tab on the upper end of the lock pins in a notch, thereby revealing whether the lock pins have a slot positioned in the “left”, “center” or “right” positions, which can be read from indicia on the lock pin decoding body, and further revealing if the lock pins have a “fore” or “aft” facing wedge, which can also be read from indicia on the lock pin decoding body.
