In today’s world of crimes and criminals, nobody and nothing is ever safe anymore. It is difficult to trust even people who are close to you from stealing and cheating on you. But since science and technology are advancing at every moment, we now have ways to prevent from losing what is ours. Locks, safes and keys are the only solution to providing some security to our assets. The science or art of mastering and working with locks is known as Locksmithing famously. Locks here are used as a mechanism to keep safe and secure buildings, drawers, closets, cabinets, rooms or any other storage areas and facilities. A key is used to open up or access the respective storage facility. They means of opening a lock with a key can however be of two types. It may include a security token or a two- factor authentication for a stronger lock and a more enhanced security level. Locksmithing is a profession with extremely old roots. The first ever lock is believed to be made by Egyptians while the first ever key based lock was thought to be made in 704 BC during the time of the Assyrian Empire of Khorsabad located near Nineveh.

The remains of the locks found there used the same pin and tumbler method of locking and opening that we today use to build modern locks. Previously Locksmithing was a complete full time job as the people who used to get into this business were men of great skills and craftsmanship. The spent all day in cutting out and molding locks and their keys. Every lock made was almost a unique because no two locks were ever the same after they had been made. They could carry the same design but weren’t completely same altogether. The Locksmithing business has somewhat changed now. With more technology and cheap work force available, parts of a lock are developed by different people and just assembled in the end. The repairing and the renovations of the locks is also not much of a difficult or sophisticated task these days. The defected part is simply replaced by a new one instead of making a new lock or a key altogether. Now days, the basic work of a locksmith is to usually determine the level of danger or risk to an individual or institution and then accordingly suggest or recommend the types of locks and the levels of security that they would be requiring. The greater the number of security levels, the more difficult it gets for an intruder to get through to the item of interest.

Locksmiths are also of various types. They maybe commercial- working in a store, mobile locksmiths- working on a movable vehicle, institutional locksmith- locksmiths hired by some company for doing their work only and forensic locksmiths- locksmiths that essentially carry out investigational work. All such locksmiths are very good technicians and sometimes engineers too. They specialize in the areas of automotive locks, master key systems or safe locking.
