HOW A LOCK WORKSUnderstand how your lockworks. The pin-and-tumbler lockconsists of a cylinder that canrotate within its housing. Whenlocked, the cylinder is kept inplace by several pairs of pins. Thetop pin of each pair protrudesinto both the cylinder and thehousing, thus preventing thecylinder from turning. When thecorrect key is inserted, it pushesthe pairs of pins up so that thetop pins no longer enter thecylinder. When this happens, thecylinder can be turned and thelock will open.
HOW A LOCK WORKSNote the five pairs of pins. The blue pins enter When the key is inserted, the grooves and ridgesboth the cylinder and the (green) housing on the key push the pins up to the correctaround it, thus preventing the cylinder from heights so that all the blue pins are completelyturning. The springs provide resistance to keep out of the cylinder, thus allowing the cylinder tothe pins in place. turn and the lock to open.
TOOLS USED TO PICK LOCKSTorsion wrenchThe torsion wrench, is used to applytorsion to the inner cylinder of a lock, inorder to hold any picked pins in placeHalf-diamond pickPerhaps the most basic and commonpick, it is mainly used for pickingindividual pins.Hook pickThe hook pick is similar to the halfdiamond pick, but has a hook shaped tiprather than a half diamond shape.Ball pickThe ball pick is similar to the half-diamond pick, except the end of the pickhas a circular shape.Rake picksThese picks, such as the common snakerake, are designed to rake pins by rapidlysliding the pick past all the pins
TYPES OF LOCKSThe pin tumbler lock, sometimes called the Yale lock A wafer tumbler lock is a type of lock that uses a set(see Yale (company)), is a lock mechanism that uses of flat wafers to prevent the lock from openingpins of varying lengths to prevent the lock from unless the correct key is inserted. This type of lock isopening without the correct key. Pin tumblers are similar to the pin tumbler lock and works on amost commonly employed in cylinder locks, but similar principle. However, unlike the pin tumblermay also be found in tubular pin tumbler locks (also lock, the wafer is a single piece. The wafer tumblerknown as radial locks). lock is often incorrectly referred to as a disc tumbler lock, which uses an entirely different mechanism
