PART 4

The Pick Gun

At this point I'd like to introduce another picking tool that most lock pickers find at least as valuable as their favorite rake.

It uses the principle of percussion, explained earlier in this manual. When the "handle" portion of this tool is squeezed with a quick and rhythmical motion, the long needle, which is inserted into the keyway, strikes the bottom pins of all the pin stacks at once. This energy is transferred to the top pins, which of course are resting atop the bottom pins in each chamber. Because there is a separation, however infinitely small, between the bottom and top pins, the energy is not transferred smoothly and a large rift develops for an instant between top and bottom pin, sending the top pin up into the upper housing. If very slight turning tension is being applied to the plug with a tension tool, the plug will rotate if all top pins become trapped in the upper housing as a result of these continues percussions.

A much more effective tool developed out of this basic configuration, using the stored energy of a wound spring inside an enclosed body. The result is a more powerful striking force, which in fact can be adjusted with a knurled thumbscrew, and more control.

If you have one of these excellent tools, this is a great time to get some practice with it. The fully pinned practice cylinder will respond well to the use of a pick gun, as will most any residential duty lock with a relatively flat key. The gun is effective, of course, on all types of locks but more practice is needed before attempting to use one with commercial duty locks with their tighter tolerances and extreme differentials between adjacent cuts.

Even if you do not have a pick gun, you should read through the next exercise to more fully acquaint yourself with the proper use of this tool. It's almost a certainty that you will someday have one in your tool kit.

Using A Pick Gun

There are similarities between the use of the rake and how a pick gun works. As mentioned before, the rake actually uses the same principle of percussion when it is withdrawn with a snap, its tip bumping along against the bottom tumblers as it exits the keyway. With a pick gun, the tool remains in the keyway and is held at a right angle to the keyway as it is operated.
