Science of Lock Picking


The advantages of picking or other skilled methods of entry are many. With any of the picking methods presented nowadays it is necessary to practice, practice, practice. Any picking takes some time and lots of skill. Like most other things in life, it is seldom accomplished as easily as presented on media.

A good method for effective practice is to obtain a lock that lends itself to dismantling and remove all but two pins (one long and one short). Follow the techniques given until you have mastered the two pin lock and then try three pins, then four, etc. Once you have this down pat, replace the two pins with mushroom pins and start over.

Pin tumbler lock


An overview of the pin tumbler lock


The pin tumbler lock is the most widely used lock. It offers medium to high security and is found in doors, cars, and a host of other applications.

The principle of the pin tumbler is a series of tumblers resembling small pins (usually 5) held in place by other pins resting on top of them, called drivers,which are in turn, held in place by springs.

The tumblers, drivers, and springs are mounted in the shell of the lock and the tumblers extend down in to the core of the lock. When the proper key is inserted the tumblers are raised to this shear line, or division between them
and the driver pins. This shear line is located at the top of the core. When this transpires, the core may be turned freely with the key.

If a key is cut too low, the driver pins will extend down into the core; too high and the tumblers will extend up into the shell of the lock. In either case, the core is help stationary and the lock stays locked. Pin tumblers require a high degree of tolerace in lock and key making. About .002 of an inch is required for correct functioning.
