INTRODUCTION


The ancient Egyptians were the first to come up with
a complicated security device. This was the pin tumbler
lock. We use the same security principle today on millions
of applications.

The most commonly used lock today is the pin tumbler
lock. A series of pins that are divided at certain points
must be raised to these dividing points in relationship to
the separation between the cylinder wall and the shell of
the lock by a key cut for that particular series of pin divi-
sions. Thus the cylinder can be turned, and the mechanism
or lock is unlocked.

Lock picking means to open a lock by use of a flat piece
of steel called a pick. Actually, the process requires two
pieces of flat steel to open cylinder locks. It amuses me
to watch spies and thieves on TV picking locks using only
one tool. But it is for the better in a sense. If everyone
learned how to pick locks by watching TV, we would all
be at the mercy of anyone who wanted to steal from us,
and the cylinder lock for the most part would be outdated.

The actual definition of lock picking should be: "The
manipulation and opening of any restrictive mechanical
or electronic device by usage of tools other than the
implied instrument (key or code) used solely for that
device." A little lengthy, but more accurate description.
With cylinder locks, it requires a pick and a tension
wrench.

By picking the lock, you simply replace the function
of a key with a pick that raises the pins to their "break-
ing point," and using a tension wrench one rotates the
cylinder to operate the cam at the rear of the lock's cylinder
to unlock the mechanism.

The tension wrench is used to apply tension to the
cylinder of the lock to cause a slight binding action on
the pins as well as to turn the cylinder after the pins have
been aligned by the pick; this opens the lock. The slight
