Medeco

Medeco, a subsidiary of the Swedish Assa Abloy Group, is a lock manufacturer located in Roanoke County, Virginia, United States.

In the 1960s, Mr. Spain perfected a lock featuring angled key cuts with elevating and rotating pin tumblers, and submitted the design to the U.S. Patent Office.

Only a detective from New York City succeeded; accomplishing the feat a single time but failing on subsequent attempts.

Using computing power and mechanical know-how, the group developed a practical means of deploying a "bump pick" attack.

[2] The research eventually led Medeco to remove most claims from its own press that had indicated immunity to bump and pick attacks.
