To pick a lock you need feedback about the effects of your
manipulations. To get the feedback, you must train yourself to be
sensitive to the sound and feel of the pick passing over the
pins. This is a mechanical skill that can only be learned with
practice. The exercises will help you recognize the important
information coming from your fingers.
7.2 Zen and the Art of Lock Picking
In order to excel at lock picking, you must train yourself to have a
visually reconstructive imagination. The idea is to use information
from all your senses to build a picture of what is happening inside
the lock as you pick it. Basically, you want to project your senses
into the lock to receive a full picture of how it is responding to
your manipulations. Once you have learned how to build this picture,
it is easy to choose manipulations that will open the lock.
All your senses provide information about the lock. Touch and sound provide the most information, but the other senses can reveal critical information. For example, your nose can tell you whether a lock has been lubricated recently. As a beginner, you will need to use your eyes for hand-eye coordination, but as you improve you will find it unnecessary to look at the lock. In fact, it is better to ignore your eyes and use your sight to build an image of the lock based on the information you receive from your fingers and ears.
The goal of this mental skill is to acquire a relaxed concentration
on the lock. Don't force the concentration. Try to ignore the
sensations and thoughts that are not related to the lock. Don't try to
focus on the lock.
7.3 Analytic Thinking
Each lock has its own special characteristics which make picking
harder or easier. If you learn to recognize and exploit the
"personality traits" of locks, picking will go much faster. Basically,
you want to analyze the feedback you get from a lock to diagnose its
personality traits and then use your experience to decide on an
approach to open the lock. Chapter 9
discusses a large number of common traits and ways to exploit or
People underestimate the analytic skills involved in lock picking. They think that the picking tool opens the lock. To them the torque wrench is a passive tool that just puts the lock under the desired stress. Let me propose another way to view the situation. The pick is just running over the pins to get information about the lock. Based on an analysis that information the torque is adjusted to make the pins set at the sheer line. It's the torque wrench that opens the lock.
Varying the torque as the pick moves in and out of the keyway is a general trick that can be used to get around several picking problems. For example, if the middle pins are set, but the end pins are not, you can increase the torque as the pick moves over the middle pins. This will reduce the chances of disturbing the correctly set pins. If some pin doesn't seem to lift up far enough as the pick passes over it, then try reducing the torque on the next pass.
The skill of adjusting the torque while the pick is moving requires careful coordination between your hands, but as you become better at visualizing the process of picking a lock, you will become better at this important skill.
