There are many techniques or methods in picking pin tumbler locks. The most famous is by using the
tension wrench. Together with a standard
pin tumbler lock pick
(which is utilized to thrust the pins up), the tension wrench is applied to the lock's cylinder.
The pin tumbler lock is opened when all the pins are flushed with the shear line.
Another method in
pin tumbler lock picking
is through raking or scrubbing. This technique is typically applied before the lock's pins are
moved up. Again, the tension wrench is used in this method together with a wide tipped lock pick,
which is positioned at the back portion of the lock. With this process, the pins are moved upwards
when a quick pressure is applied to the lock. As a result, the lock's shear line is flushed with
the pins.
One technique (in picking tumbler locks) which does not use the tension wrench is the so-called
"safety-pin-method". However, this process can only be used in picking simple 40 mm pin tumbler
automatic padlocks. The simplicity of the padlock's design (its cylinder has only 1/8 full turn
and its pin is only composed of 3 sets) allows the picker to put pressure and raking to the lock's
side.
If there are pin tumbler locks that can easily be picked, there are also models that have
exceptional safety systems. With especially designed security pins (such as serrations, mushroom
heads, and spool shapes), these locks are almost impossible to pick. These security devices cause
the pins to bind in different positions other than their desired places.
The fastest way in picking the pin tumbler locks is by using a vibration pick or gun. The gun
shots all the bottom pins. This method can be compared to the billiard's cue ball wherein the
energy is passed to the top pins.
