*Locksmiths and lock picking hobbyists have long known about a vulnerability in American Lock's design called "The Bypass". Essentially, because of a design flaw in the American lock cylinder and with a special tool inserted, the cylinder could completely be bypassed and the lock opened in seconds. No picking needed. This obvious problem was somewhat solved by the manufacturer by adding what they call a "anti bypass plate". This eliminates the quick tool insert and bypass method but any American lock fitted with the anti bypass plate can still be defeated with a special punch through tool and bypass pick. It takes much longer but technically it is still a vulnerability.
Our 70 series padlock internal design is such that no anti bypass plate is needed and the bypass tool has no effect.
