How to Pick a Lock with a Bump Key
From the “use this for good, not evil” files comes a fascinating instructional video on how to pick a lock with a “bump key“—a key modified to fit and open any lock. Like the instructor in the video says, thieves have been using this technique for a long time now—so it’s interesting (in the “knowledge is power” kind of way) to see how it’s done. Before you start making evil plans, keep in mind that most states in the U.S. consider a bump key a burglary tool so don’t go getting yourself arrested.
