Sparrowvsrevolution writes: At the Def Con hacker conference Saturday, MIT students David Lawrence and Eric Van Albert released a piece of code that will allow anyone to create a 3D-printable software model of any Schlage Primus key, despite Schlage’s attempts to prevent the duplication of the restricted keys. With just a flatbed scanner and their software tool, they were able to produce precise models of Primus keys that they uploaded to the 3D-printing services Shapeways and i.Materialise, who mailed them working copies of the keys in materials ranging from nylon to titanium. Primus high-security locks are used in government facilities, healthcare settings, and detention centers, and their keys are coded with two distinct sets of teeth, one on top and one on the side. That, along with a message that reads "do not duplicate" printed on the top of every key, has made them difficult to copy by normal means. With Lawrence and Van Albert's software, anyone can now scan or take a long-distance photo of any Primus key and recreate it for as little as $5.
