Most of the contrivances for locks were supposed to possess some particular advantage, such as strength to resist violence, or security against

being picked.

Some speculators have acted upon a different principle alto-

gether—that of attaching an alarm, a large bell, a species of fire-arms, &c. to a lock, in such a manner that an attempt to violate the lock would set the

bell a-ringing, or discharge the fire-arms ; thereby causing a great noise and confusion, that the depredator might not escape. Our limits will not permit us to enter into the details of all the schemes that have been proposed to give security to locks ; but we shall notice principally such as have come into use by their own recommendation. ... The subject of locks is so very extensive, that it would far exceed our limits to give a description of all the different forms and arrangements that have been proposed by various persons.

helps to understand how they work.

That is why this book also

rovides 4 detailed and illustrated explanation of how the various locks

will actually work. You will find there are many times when this knowledge be invaluable when learning or in the field. The actual methods of lock picking are really quite simple. You are “ust exploiting the design of the lock in order to open it without the key.

Applying these techniques, however, can prove to be quite difficult. As you ractice, you will find that a lock that used to take you an hour to pick might now only take you ten minutes. A lock that used to take you five minutes might now only take you a few seconds. As you practice these skills, you

will become much more efficient.

This book does not go into detail on the legal implications of lock picking.

You are responsible for determining your own local laws and regulations.

If you are using this book as a textbook in a course please ask your instructor any questions you may have. Do not do anything illegal. Period. You will find that there are many legitimate times when having the ability to pick locks is very useful. Beyond the many professional locksmiths around the country who make a good living doing legitimate lock picking, the skill of lock picking is useful for many professions. Law enforcement officers, emergency personnel, magicians, repossessors, and others are often called

upon to pick locks in their professional line of duty. Always keep in mind why you are picking any particular lock, and realize that there is often a better way to bypass it, which may ignore the lock completely.

Locked Shackle

Warded Padlock - cutaway

Now we will take a closer look inside the lock for a better understanding of

how it works. In this example, two of the slabs are special and provide the actual locking mechanism.

The picture above shows just those two slabs

and how they hold the shackle in place.

Each of them contains a piece of

spring metal that rests in a notch in the shackle. As long as this small piece of metal is in the notch, the shackle cannot be raised and will remain in the lock. The key, or other tool, simply bends this metal spring out of the

way. Once it has cleared the notch, the shackle is free to leave the lock and

another spring will pop the shackle out. It is important to note that this lock

has two metal pieces locking the shackle in place, one on each side of the shackle. The lock will not open unless both metal pieces are moved out of the way simultaneously. This complete cutaway view demonstrates how everything fits together. The warded and locking slabs have been shaded to demonstrate their internal arrangement. You can see how they can be rearranged to require a

different key. Each side of the shackle has a metal spring holding it in place on opposite sides of the lock. One side of the key needs to push the metal spring down, while another portion of the key needs to push the other metal

spring up.

Professional handcuffs allow for double-locking. They are designed to prevent further tightening once they are double-locked. This helps diminish undue and unintended bruising on those who must wear them. It also makes the cuffs harder to shim open or pick. The key must first be rotated in one direction then the other to completely open the cuffs.

Identifying Pin Tumblers Pin tumblers can be found in many places, most commonly on house

deadbolts, doorknobs, cabinets, padlocks, etc...

They usually have pins

visible in the keyway. These pins are often round and somewhat pointed at the end. The pins are spring-loaded and will spring back down when you push up on them. They look somewhat similar to wafer tumbler locks, which will be discussed in a later chapter.

How Pin Tumblers Work It may take some time to grasp the inner workings of the pin tumbler. So, please don’t get discouraged. If you are not completely comfortable with the concept, read this section over again a few times. In addition to the

When you are done filing all of the blanks, there should be at least one key

with a different pin groove depth that also works the lock. However, it is also possible that there are more. If there is only one pin groove depth that has an alternative depth, then you already have all the information you need to make the master key. If there are multiple pins with alternate depths, then you might have to file several potential master keys. First, file a key that has all the alternate depths. If the all-alternate depth key doesn’t work on other doors under the same master key scheme, then you may need to try making keys with some of the other combinations of original and alternate depths. Some master key systems can be very complex with different master keys working different sets of locks.

The mushroom driver gets its name because its shape vaguely Tesembleg a mushroom. It can be installed and used just like a normal top pin. The indentation in the side of the pin allows it to false set as it is being pushed up with a pick. The top edge of the head of the pin will make contact with the hull, providing the false set. The top pin will remain bound between the hull and the plug, allowing the bottom pin to fall when pressure from the pick is removed. In reality, the pin column has not

yet been raised enough, and the head of the mushroom remains lodged in the plug.

A second popular design for high securi pins is the spool pin. They are designed t provide a very deceiving false set. Similar to the mushroom pin, the bottom of the pin

is wider than the middle. It can also be very difficult to detect their presence until it is too late. The side of the pin is designed to catch at the shear line. The end of the spool can catch on the hole entering the hull, making it very

difficult to push up while applying torque to the plug. You can deal with spool pins the same as mushroom pins. Release some torque tension to

tip :

Round Tension Tool

With these tension tools it is possible to rotate the plug in either direction with equal ease.

Unlike the traditional torque wrench, this tool is also

less likely to interfere with or be disturbed by the action of a pick or rake The torque that this tool provides can be more balanced than the regular torque wrench, because the two points where pressure is applied are on the opposing far ends of the keyhole. The simplest of these round tension tools has a fixed distance between the two L-shaped wires. More advanced models allow the user to match the exact shape of the keyway by altering the distance between the wires. These improved versions have a spring-loaded button that is pressed to bring the two wires closer. The tool is then inserted into the keyway and the button is let go. The spring pushes the wires apart until both wires are pressing on the opposite sides of the keyway.
