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:
“How can you tell if you discipline effectively? Ask yourself if your disciplinary methods generally produce lasting results in a manner you find acceptable. Whether your philosophy is democratic or autocratic, whatever techniques you use—reasoning, a “star” chart, time-outs, or spanking—if it doesn’t work, it’s not effective.”
—Stanley Turecki (20th century)
