Looking at how things work, there is a new method used to pick locks that works a little to well. It is a thing called a bump key. To make one for this cylinder lock would be tricky. Still, it could be done. The principle is that you bounce the tumbler pins in, while holding light tension. The inertia of the pins pushes the pins in. As they return, the tend to catch were the would normally turn. I've seen one on the web demonstrated. They are quite remarkable as to how easy they work. ( way too easy ) The idea of making one for your lock is to allow the cylinder to only turn part way between pin angles. Once it has rotated that much, you can then measure the pin depth and make the key. You could make one from a blank key and use a rubber washer to improve the action. You'd remove the piece that holds the key in the lock and make a holder block that would allow a partial turn so that it would stop, at the right angle, between locations to make measurements for the new key. It is not the traditional picking method but having seen it in action makes traditional feeling the pins obsolete. Dwight
