Anti-picking Methods
To prevent picking of locks, numerous methods have been employed throughout history, in addition to locks which must be reset using a master key if they have been tampered with e.g. the Chubb detector lock.
Today, anti-picking methods include the use of side wards which obstruct the key way, and security pins. These are pins which are shaped like a spool, mushroom, or barrel with the effect that they feel as though they have set when in fact they have not. Overcoming these pins involves reverse picking: the process of first setting all pins above the shear line and gradually reducing tension.

Famous quotes containing the word methods:
“We are lonesome animals. We spend all our life trying to be less lonesome. One of our ancient methods is to tell a story begging the listener to say—and to feel—”Yes, that’s the way it is, or at least that’s the way I feel it. You’re not as alone as you thought.””
—John Steinbeck (1902–1968)
