MIT Researchers: Printable Keys Make Mechanical Locks Insecure
6th August 2013
The researchers focused their efforts on Schlage Lock Comp.’s flagship secure-key solution, dubbed Primus. Primus keys carry glaring “do not duplicate” message, which references Schlage’s patent on its two-tracked toothed key design, U.S. Patent No. 5,808,858. The patent was filed in 1997 and granted in 1998. The keys are typically used by law enforcement, mental health institutions, and military detention centers; they are even personally recommended by famous lockpick expert Marc Weber Tobias who wrote the much-referenced 1970 textbook on security Locks, Safes, and Security.
