Locksmiths Inner West Sydney Says:
Many locksmiths are self-employed and lead a very independent existence. Because the skill is so specialized, there are few opportunities for “staff” locksmiths. These independent locksmiths often work odd hours, opening doors in the middle of the night for stranded homeowners and drivers, as well as installing security systems during the hours when buildings are being used the least.
Locksmiths are required to obtain different types of licensing, depending on where they work. Locksmiths are also traditionally “bonded” which is a legal means of assuring their trustworthiness to their clients. Traditionally, locksmiths undergo an apprenticeship though many have received training through an employer or by attending a school specific to the trade.
Although a locksmith’s job seems very exciting and appealing to most people, there is a lot of skill, education, and experience involved.

History of locks
Wooden locks and keys were in use as early as 4,000 years ago in Assyria [1]. The first known lock with a key is a pin lock. The lock is strung on a rope hanging out of a hole in a door. A cylinder of wood with a hole drilled through its axis is the key, the length of the cylinder being the critical factor. Then the key is inserted into the hole and the bolt is pushed the correct distance. To lock the door,they just pulled on the rope to extract the key cylinder and simultaneously pulling the bolt closed. This type of lock is still in use in certain parts of the world. A danger of this lock is a vandal can push the rope into the hole — an ancient equivalent of putting glue into a lock.
Early improvements in pin locks included increasing the number of pins to increase security, and changing the orientation of the pins to allow the key to provide the unlocking force instead of a rope. Thus establishing the principles of the modern pin tumbler lock.
Next was developed a warded lock that is still used in modern times when the security required is not high and cost is a significant factor. It is the first lock design to have a key recognizable to a modern western person. Lock puzzles were used to obscure the locking mechanism or even provide a nonfunctioning lock for the thief to waste time on.
Locksmithing began as the science and art of making and defeatinglocks. A lock is a mechanism that secures buildings, rooms, cabinets, objects, or other storage facilities. A < is often used to open a lock. Means of opening a lock often include what you know (a combination), what you have or what you are (Higher security is attained by selecting one from each group - generally 2 keys is not as secure as one key and one fingerprint.)
