A locksmith’s job involves installing, fixing, picking and removing lock systems and to do so a basic understanding of how a lock works is needed. The basic system of a lock, whereby a key is used to move a metal peg into a hole in the door frame is essentially the same across designs. However it is the manner by which this is achieved that has changed and evolved over time.

                In the old days, when most locks used the same gate key, this was a fairly simple matter (though the very earliest form of lock was actually found in Ancient Egypt). Gate keys, still used today though mainly as a deterrent/design feature for large gates and churches, have a very simple anatomy consisting of a blade (the actually ‘key’ bit that works with the mechanism) near the end, and a long handle which holds the blade at a right angle. This means that only a very limited number of permeations are possible, as only the distance of the blade from the end of the key and its size is what determines which lock it will fit and a persistent thief could easily replicate the key or turn the lock mechanism by other means. They are also known as warded locks and occasionally found on cupboards and drawers.

                Over time however locks have become more sophisticated. After the introduction of locksmith guilds in the middle ages, the art form progressed drastically as incidences of crime increased giving rise to a large industry. Now locksmiths were encouraged to design more and more complex designs that would be able to keep out greater numbers of intruders and be harder to pick. In order to become a ‘master locksmith’ within a guild the locksmith would have to design a new and innovative type of lock which would then be put on display within the guild or in museums. This obviously gave rise to more and more complicated types of lock.

                Cylinder locks are far more common today and these work very differently. Here the ‘cylinder’ element of the lock actually consists of a cylinder within a cylinder and it is the job of the inner chamber to turn and move the lock mechanism. Normally however this is prevented by a number of small pins of varying lengths which rest inside the chamber. It is the job of the blade of the key and its straight teeth then to push these pins out from the centre of the cylinder so that the lock might turn. Cylinder locks can easily be unscrewed and replaced by locksmiths if the locks need to be changed. Also popular are lever locks which utilise keys similar in design to gate keys.

                Many businesses and organisations however now use digital locks with key cards or numeric coding systems to release or engage a powerful magnetic lock. These systems have the advantage of foregoing the need to copy many different keys and also negate skeleton keys or lock picks for slightly better security. On the downside they are susceptible to hacking, power outages and are fairly expensive to install.

work of a blacksmith consists of installing, fixing, collection and disposal of this structure and a basic understanding of how a block is needed. The base system of a block, so that a key is used to move a metal pin in a hole in the door frame is essentially the same for all designs. However, as this is achieved has changed and evolved over time. In the past, when most of the locks use the same key door, it was a pretty simple question (even though the first form of lock is currently in Egypt). House keys, but still used primarily as a deterrent / design capability for large doors and churches, have an anatomy consisting of a simple blade of bits (actually the “key” that works with the mechanism) toward the end, and a long handle that has the blade at right angles. This means that only a very limited number of permeations are possible, as the distance from the road until the end of the key and its size is what determines who will be integrated lock and a persistent thief could easily double or activate the key lock mechanism with other means. Also known as locks Warded and occasionally found in ArmariCES resulting increase in crime in a big industry. Locksmiths are now being encouraged to design ever more complex designs that would be able to keep intruders away more and more difficult to collect. To become a blacksmith “master” in a guild of blacksmiths will design an innovative new type of block that would be put on display at the guild or in museums. Obviously, this has resulted in more and more complicated types of block. lock cylinders are much more common today and they work very differently. Here the element of &am
