And another thing! The French Patent office many years ago ceased allowing patents on keys that did not have a movable element, which led to the development of many keys that cannot be readily duplicated without access to either the restricted blanks or very serious equipment & knowhow with which to make the blanks. These systems remain well outside the realm of 3D printing. DOM Saturn[0], Mul-T-Lock Interactive (and up), Vachette Radial[2] and a handful of others.[3] Mechanical locks are far from dead, but I'd love if someone reading this took it as a challenge to reproduce keys with movable components. I'm a big proponent of pushing these systems and finding ways to circumvent them, using any technology available. I just don't like it when the response is to throw the baby out with the bathwater.
