We have won five National Titles and ten State Titles. It is very important when you do the exercises that you not move on to the next until you have completely and comfortably mastered the exercise you're working on. You have to be prepared to pick locks in either direction. You must be careful to avoid touching the front-most pin with the blade of the tool, but this position has the advantage of allowing maximum room to maneuver the pick. Insert the tip of the tool in the keyway, allowing enough room for your pick to enter and manipulate the pins. In a billiard room designed by Robert Couturier, a Zaha Hadid sofa for Sawaya & Moroni and pair of vintage Italian armchairs complement a reproduction by Lutyens Furniture & Lighting of the original billiard-table light. The nitrocellulose lacquer yellows and cracks over time, and custom shops will reproduce this aging to make instruments appear vintage. If this happens, you won't get the lock open until you release torque and start over. An important skill when picking is to recognize when this has happened so you don't waste time before you start over. Continue with the one pin lock, trying to apply less and less torque each time.

Each segment of the string (bead) represents one point as the players can move one or several beads along the string. It can become very tempting to "cheat" a bit here and move ahead the moment you get a difficult lock open the first time, but that will only make the rest of the course that much harder. This keyway is a bit more "open" (it's intended to allow several different key profiles to fit in it), and so requires the use of a larger pick than the Arrow AR1 keyway does. 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. One of them should feel springy, just as it did with no torque applied. If both feel springy, you're not applying enough torque (which is unlikely). Reset the lock by returning the plug to the vertical locked position and try again but with torque applied in the other direction. You'll notice that it resists more than it did in the previous exercise because its top pin is pinched between the plug and the shell at the shear line by the torque you're applying.

It's binding because it's the one most out of alignment in the direction you're turning, and so its top pin is being pinched (gently) between the plug and the shell. Take frequent breaks, and don't try to complete the whole course in one day. Try each of your torque tools in the lock. See Figure 5. With the tool in the keyway, apply torque and try to turn the plug. Figure 4. Manipulating pins. Find the ward directly under the pins and pivot the shaft of the pick at the font of the keyway. That means being able to reliably pick the lock, both clockwise and counterclockwise, and being confident that you know how you opened it. Understanding the theory of lock picking is only a small part of being able to successfully pick locks. The keyway is relatively open and easy to move a pick through, making it a good starting point. Move your fingers close to the keyway as you do this.

See Figures 3 and 4. Once you're comfortable with the AR1 keyway, move on to the "Ilco SX" keyway locks and repeat the exercise. This keyway is common in commercial and residential locks in the US, and is close in shape and size to a number of other common keyways, including that used by Kwikset, a very popular (and easily defeated) line of US residential locks. When you feel confident visualizing and using picks to maneuver around the pins in the AR1 and SX keyways, you're ready to start actually opening locks. Work your pick into the keyway and feel the pins. It just doesn't work! While continuing to apply torque, slowly push the binding pin up. You should be able to confidently find each pin and push it all the way up, without jamming the pick against anything or moving other pins. The pins toward the back may feel a bit different from the pins in the front. So I'm going to shoot here and put a little bit of left spin, maybe two tips of left, and that should be it. Apply some torque to the plug and feel the two pin stacks with your pick. For this exercise, you'll be using the two pin AR1 lock.
