I build this in response to this question (http://bricks.stackexchange.com/quest...) on the LEGO Stack Echange.

In a standard pin tumbler lock system, if the right key is not pushing on the pins, both the driver pins and the key pins can prevent the rotation motion. If the key tooth is too low, the driver pins is blocking and, if the key tooth is too high, the key pin is blocking. In my system the driver pins are doing both functions.
