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:
“In inner-party politics, these methods lead, as we shall yet see, to this: the party organization substitutes itself for the party, the central committee substitutes itself for the organization, and, finally, a “dictator” substitutes himself for the central committee.”
—Leon Trotsky (1879–1940)
