The other should give you a bit of resistance. It feels "squishy," with more resistance than from just the spring. Learn what a pin in that state feels like. Set/not-binding. The pin stack was already picked. Overset/binding. The cut in the pin stack is past the shear line. Because there are two independent shear lines, there is no way to control, or even tell, at which shear line a given pin stack sets. Congratulations, you've picked the (two pin) lock. LAB is a lock pin and locksmith tool manufacturer. For this exercise, you'll use your torque tool and pick on the two pin lock to put the pins in each of these states to learn what they feel like with your pick. The Y1 keyway is one of the toughest you are likely to encounter in real lock installations in the US. If you inadvertently push a pin up too far or are applying so much torque that more than one pin is binding, you may have an overset pin instead. Much of this is simply a matter of individual preference, but certain choices here can also have an impact on performance. Picks probe and lift the individual pin tumblers through the keyway, while torque tools control the degree and force of plug rotation.

The basic recommended pick set for this course includes four picks and four torque tools. Unfortunately, many of the commercially available lock pick kits consist mostly of useless gimmicks. As you progress, you should know the state of the lock at all times: which pins are set, which aren't, which one is binding. You should already be able to distinguish between an unset pin that isn't binding, an already set pin, and a pin that is binding. It's binding because it's the one most out of alignment in the direction you're turning, what is billiards and so its top pin is being pinched (gently) between the plug and the shell. Check out our shop! Master keying does not introduce any significant complications for lock picking. They allow very precise control over torque, especially when employing advanced picking techniques that involve a slight reversing of the rotation of the keyway. Note that the pick should be held mostly by the shaft of the tang, not the "handle." This allows better control and feedback. Longer handles are as a rule better in torque tools; the farther from the plug the torque can be applied, the easier it is to detect and control fine movement.

Spend a lot of time playing with the three pin lock so that you can recognize the pin states easily and naturally. If you're not in my seminar, the references to the lock boards in the lab don't apply, of course; you will need to configure your own training locks to follow these exercises. You'll need to be careful not to disturb the long pin when you push the short pin up. If you release pressure with your pick while still applying torque, the bottom pin will drop freely, and will not have any spring pressure if you try to push it back up. The keyway is relatively open and easy to move a pick through, making it a good starting point. Several positions are possible; here a vertically-oriented torque tool is used at the top of the keyway. It won't turn, of course, because the cut of the (single) pin stack is still below the shear line and its top pin is preventing the plug from rotating. Small digits represent short bottom pins (that must be pushed up more to reach the shear line); large digits represent longer bottom pins (that need only be pushed up a bit). The large board has locks with eight different keyways, representing many of the most common keyway designs used in the US.

Over the years, the locksmithing industry has settled on a number of "standard" pick designs. Most of the esoteric pick designs in the huge, overpriced sets you see on the web and from locksmith suppliers are useless, and eventually end up being discarded in favor of the basic hooks. The fourth pick is a "rake" of a long sawtooth design (the "Ripple"). The shape of the tip is the most obvious difference between picking tools, with hooks, half-diamond, ball, double ball, wave, sawtooth and other styles available. Picking tools are designed to perform one of two basic functions: manipulating pins and turning the plug. Apply some torque to the plug and feel the two pin stacks with your pick. Keep practicing with the two pin lock, trying to lighten your touch as you do, and making sure you consistently can pick the pins one at a time. While a fairly wide range of torque will sometimes pick these locks, try find the lightest torque that works.
