Various Techniques 
                 of
            LOCK PICKING

     Various techniques are known for opening doors and windows without
picking the lock or harming the premises.  And while all these
"tricks of the trade" will not work in every situation, one or more will
succeed in most situations.
     If your check determines that the door opens outward and the hinges are
affixed to the outside of the door,the simplest way through the door is
by removing the hinges.  On older buildings it is only necessary to use
a screwdriver and a hammer to tap the hinge pin out.  The door may then be
removed from the frame without damage to either the door or lock.
     Many modern buildings today are equipped with a set hinge pin on doors
opening outward.  These have a set screw which is concealed when the door 
is closed.  Frequently, because of sloppy workmanship, these screws have
not been tightened, allowing removal of the hinge pins just as readily as that
of a loose pin hinge.  Even when you find a tightened hinge pin, it simply
means you must apply a little more force.
     The set screws for most hinged pins do not penetrate to any great depth;
consequently, the added applied force will usually release the pin.
     Shove knifing or shimming is likely the oldest method for opening
a lock without a key and it is still useful in many situations.  If a 
spring latchbolt holds the door in  place and the bevel of the latch faces
the outside, the latch can be sprung with a piece of flexible plastic, a
thin screwdriver or a thin metal shove knife.  Slide the knife between the
door and the trim near the area of the latchbolt, freeing the door.
     When the bevel on the latchbolt faces inward, you will need to make a
curved or L-shaped shove knife, constructed from one inch spring steel
or sheet metal.  To retract the spring latch, simply insert the shove knife
between the door and the trim near the area of the latchbolt, placing the 
L-shaped end of the knife behind the latchbolt; pull it toward you.
     Sometimes a sharp ice pick will suffice for both spring latch 
positions.  Determine the area of the latchbolt and puch the pick firmly
against the bolt while sliding the pick toward the door.
     To defeat a rim mounted deadbolt lockset, place a hydraulic jack, with
two six inch sections of two-by-fours, across the door frame.  Turn the jack
slowly, just enough to free the deadbolt.  This is possible due to the
tolerances allowed between the carpenter's rough frame and the 
prefabricated outer frame measuring up to an inch on either side, more than
enough to defeat most deadbolt locks.
