Locksmithing is a centuries-old trade that has evolved significantly over time. The earliest known locks were used in ancient Egypt and Mesopotamia, around 4000 BC. These locks were simple wooden devices that used a wooden bolt to secure a door. The key was a wooden peg that fit into a hole in the bolt, allowing the door to be opened.

As time passed, locks became more complex and sophisticated. In ancient Greece and Rome, locks were made of metal and used a series of pins and tumblers to secure a door. These locks were still relatively simple, but they were a significant improvement over the wooden locks of earlier times.

During the Middle Ages, locksmithing as a trade was born, locksmiths began to specialize in creating locks for homes, buildings, and even for the royal courts. These locks were made of iron and were very difficult to pick or break. They used complex mechanisms such as ward locks, lever locks, and even combination locks.

In the 18th century, the Industrial Revolution brought new tools and technologies to the locksmithing trade. This led to the development of mass-produced locks that were more affordable and accessible to the general public. The invention of the pin-tumbler lock by Linus Yale Sr in 1848, which is still widely used today, was a major breakthrough in the field of locksmithing.

In the 20th century, locksmithing continued to evolve with the advent of new technologies such as electronic locks, keyless entry systems, and biometric scanners. These advancements have made locks more secure and convenient than ever before.

Today, locksmiths continue to use traditional tools and techniques, while also adapting to new technologies. They are responsible for installing, repairing and maintaining locks, safes, and other security systems for homes, businesses, and other buildings. Locksmithing is a fascinating trade that has a rich history and continues to evolve to meet the changing needs of society.
