We use locks in a variety of places and in many different ways. Knowing which lock to choose or understanding just what a type of lock was created to do will determine its placement and use. We use locks to protect and safeguard items that are special to us such as possessions and property.

Most locks are fundamental and operate based on some very old principles of locksmiths and mechanical engagement. Knowing which is which will save you a great deal of time and confusion when deciding where to put a lock either in your home or your business.

You may also save some money when you head out to that big box store or are shopping your way around Amazon for just the right lock. Understanding how locks work is a simple process, but there will be some basic knowledge you will need.

A Regular Lock in Your Door

For the purposes of this beginning look at locks, a “regular” lock is one you will often find in your front door. These are locks that always require a key. The mechanism called into play include a bolt that moves inside a door into the frame of the door. These are called spring dead bolts.

The Main Body or Cylinder

The place where you insert the key is known as the cylinder. It is a small vertical opening in the front of the lock and usually has some irregular edges. The shape of the key matches the shape of this opening allowing only just the right key to be inserted into it. This shaping of the key is a built in security measure that confirms it is only your key and will not function in any other lock.

The Pin Tumbler

The pin tumbler is used inside cylinder locks and involves the engaging and disengaging of a set of pins. These pins are spring loaded and keep the cylinder from moving. When the key is inserted into the cylinder, the specific shape pushes the pins up toward a set of grooves. When the pins are placed into the correct groove, then the cylinder will turn, usually clockwise. When the cylinder turns, the door will open.

There is a section of the cylinder that meets with something called the “plug.” If an unusual or incorrect key is inserted into the front of the cylinder, then the pins do not match. This mismatch causes the cylinder to stay where it is and no rotation occurs. When the correct key is used, the “plug” will freely move and the door will open.

It is handy to only have a cylinder in use inside the dead bolt. If a key is lost or damaged and a lock needs to be re keyed, it can be done by simply changing the cylinder and not the whole locking mechanism. If you are a “do-it-yourself” type then this design is great for you. All you have to do is replace the cylinder!!

The Bolt and Latch

There is a piece of metal that extends from the door into the frame. This metal is what locks the door and keeps it secured. For our purposes, when a spring bolt is in use a spring clip is employed to propel the bolt into the door frame. When the bolt lock is unlocked the spring it compressed and therefore full of energy that can be released. When released, the energy propels the bolt forward and into a locked position.

Of course, you may also just use a complete deadbolt that can be secured by turning the key or operating a knob on one side of the door.

Tubular Pin Tumbler Locks

This type of lock is also known as the radial or circle pin tumbler lock. They work basically like the spring loaded pins, but have a circular pattern to the pins instead of pins aligned linearly. In this type of lock, the pins are pushed toward the front of the lock and this action prevents the plug from rotating. There are indentations on the key that are pushed against the pins which releases the cylinder.

The Strike Plate

In this lock, the bolt extends from within the door into the frame or wall. The bolt is extended into something called the box. The box is designed and placed in such a way as to hold the bolt, thus rendering the door immovable.

The strike plate is attached to the wall or door frame and functions as a guide for the bolt. The strike plate must be placed over the bolt hole in such a way that allows the bolt to find the hole every time. The strike plate also adds an extra dimension of stability to the entire locking mechanism and its location in the door and door frame.

The sophisticated designed locks we know about today had their start centuries ago in Egypt. Around 1848, the pin tumbler lock was created and the design has held true since then. Today, we have timed locks, electronic locks, locks operated by apps, and locks that involve the use of highly complicated software algorithms. You can feel confident when placing a spring lock or dead bolt in your home or business. They have proven their worth for years.

Famous Locksmiths

Famous Locksmiths

The Famous Ones

Did you know that locksmiths have never wanted to be famous? The very nature of locksmith is that they know something that nobody else knows and are in possession of a set of skills that no one else has mastered. Locksmiths like to keep a low profile and have done so for centuries. The skill set they hone to a striking point is one that the average citizen neither has or cares to have. Here in the 21st century, locksmith still has that air of secrecy about it, but we have become interested in knowing who is providing the service.

If you can’t name some locksmiths from history, it is no major surprise. The very famous locksmiths who became well known for their skills started as purveyors of entertainment to the public by opening seemingly impossible locks made of wood, stone, brass, rope, and leather. The method by which they would either loose themselves or gain entry was kept a secret and the general public went away stunned, confused, and amazed with the skill and showmanship of the locksmith on stage.

Robert Barron

Consider Robert Barron, an Englishman made famous by improving the security of a lock by creating the double tumbler. He did not have the advantage of computers, technology, or electronic means to increase this level of security in locks. He did so by the power of his mind and the work of his hands to create a device that would be viewed as an 18th century masterpiece.

The lever tumbler lock is a lock that uses levers to stop the bolt from moving. The tumbler is lifted to a certain height which allows it to slide past the tumblers. The number of levers vary depending on the level of security needed. Locks with levers use a bitten key that is either singular or double. These can be found in southern and eastern Europe in doors, barns, and other types of buildings.




Jeremiah Chubb

In 1818, Jeremiah Chubb received a patent for the detector lock. The Chubb detector lock is a variation of the lever lock and has as its major goal to detect and prevent picking by others who would gain entry for less than honorable purposes. This detector lock is also fitted with a relocker which serves to stop entry attempts and gives an indication that entry has been attempted.

The brilliant part of this kind of lock is that when someone attempts entry, it is designed to jam in a locked state until a regulator or original key is used to turn it in a different way. When the owner of the lock finds it in this state, it is a clear indication that the lock has been tampered with. Further, when the lock is tampered with the picker is faced with the added problem of having to reset the detector mechanism to attempt another entry. This level of complexity slows down the entry process significantly and often exceeds the skill level of the person attempting entry. This kind of lock remained unpick-able for 33 years and came into existence after a government sponsored competition.


King Louis XVI

Louis XVI,  the King of France was also an accomplished and famous locksmith.

During that era, children were encouraged to pursue both liberal arts interests and interests in practical matters. King Louis-Auguste was influenced by his parents to pursue the science of locksmiths and as a result the king became quite proficient at design, implementation and entry into locks.






Harry Houdini

Just the mention of this man’s name conjures up memories of consummate entertainment and masterful skill in escapology. His fame continues into this century and he remains the quintessential locksmith and escape artist that modern entertainers seek to emulate.

In regard to locksmiths, Houdini started learning these skills at an early age. Born Erik Weisz in 1874 and hailing from Hungary, he started as a vaudeville and circus performer. Originally known as “Harry Handcuff Houdini,” who challenged police departments all over Europe to contain him. His skill set included the use of ropes, hanging from skyscrapers, straitjackets, chains, being buried alive and holding his breath for long periods of time while submerged in water or milk!
