This lock has been sitting in a drawer for a couple of years because it frustrated me so much when I first got it. The plug turns very easilly and there is no spring in the tail piece to help the plug return to its "resting position" so you need to find a turning tool that fits the keyway very closely so that you can help the plug with the counter rotation produced by all of the spool pins that are in this thing. If you want a cheap challenge that will make you feel really accomplished, this is a decent choice.
