It's hard to learn these skills all at once on off-the-shelf commercial locks, but that's what many people who try to learn lock picking end up doing (before giving up in frustration). Repeat until lock turns: - Locate the pin stack that's being pinched at the shear line (it resists slightly when pushed up) - Continue to push that pin stack up until its cut reaches the shear line and the plug turns slightly. To neutralize a partially set spool or mushroom pin, reduce torque and push the pin up, allowing the plug to rotate backward a bit as you do. Other names for the torque tool are turning tool, torque wrench, torsion wrench, and tension wrench. This style of tool is especially useful for holding open automotive locks that have spring-loaded dust covers. The form of torture that’s like people who don’t like silence, so they have the radio on or something, you see? Like in the sentence: "It is raining." What is this "it? And its purpose is either for summoning people to come to something, like church bells, or for keeping a rhythm in certain chants. I want, first of all, to explain to you the gadgetry of meditation in case any Protestant-minded people should be frightened by a certain ritualistic atmosphere.

Because it was, after all, an idol. Other classes of attack, not discussed here but at least as worthy of study and scrutiny, include lock decoding, which is concerned with producing a working key based only on access to the external interface of the lock, lock bypass, which aims to unlatch the underlying locking mechanism without operating the lock at all, and forced entry, which, as the term suggests, involves the destructive application of force to the lock or its surroundings. The principles and skills of lock picking, once mastered, can be applied against the vast majority of commercial pin tumbler locks, and the basic tools, if somewhat unusual, are quite simple. Figure 1. A pin tumbler lock cylinder. The height (or cut depth) of a key under each pin stack position is called its bitting; the bitting of a key is the "secret" needed to open a lock. See Figure 1. (In practice, the cuts are produced by stacking pin segments of particular lengths, not by actually cutting the pins; hence the term "pin stack.") With no key in the lock, all the pin stack cuts rest within the plug.

If this pin stack is slowly pushed up with torque applied to the plug, eventually its cut will reach the shear line and the plug will turn a bit more. See Figure 2. The plug will be blocked from rotating if any pin stack is lifted either not far enough (with the cut still in the plug below the shear line) or too far (with the cut pushed above the shear line and into the shell); to rotate, all pin stacks must have a cut at the shear line. Around the circumference of the plug is a shell, which is fixed to the door or container. In the locked state the plug is prevented from rotating by a set of movable pin stacks, typically under spring pressure, that protrude from holes in the top of the opening in the shell into corresponding holes drilled into the top of the plug. The top pin of the most misaligned pin stack becomes "pinched" at the shear line between the plug and the shell. Now the plug is being prevented from moving by the next most misaligned pin (which, in this case, is the other pin, since there are only two). For those unfortunate neo-anti-Luddites who refuse to acknowledge the value of anything not available on the Web, I suggest, at a minimum, reading the MIT Guide to Lockpicking, which, while not perfect, has the virtue of being free (and readily available online).

The book is an encyclopedic guide to mechanical locks, how to evaluate them, and how to defeat them, aimed primarily at investigators, law enforcement and intelligence operatives. Surreptitious entry (e.g., for espionage or law enforcement surveillance) is likewise often best accomplished by obtaining a key or through the use of specialized decoding or bypass tools designed to quickly and quietly defeat the locks used by the target. A variety of schemes are used to key the sidebar. Good tools are important, to be sure, but once a few basic tools are available the student of lock picking is usually better off investing in new locks on which to practice rather than in new picking tools. That's it -- now you know almost everything there is to know about lock picking. Now release torque and start over, taking care to pick all the pin stacks with spool/mushroom pins while leaving at least one regular pin stack unset (this will require a light touch and good sensitivity). Each pin stack is cut in one or more places perpendicular to its length. Torque tools may be oriented vertically (with the handle in line with the keyway) or horizontally (with the handle perpendicular to the keyway); different people have different preferences.
