Learn how different types of locks work, from early to modern, and the components that make them secure. The Captivating History of Mechanical Locks Which Originated Over 6,000 Years Ago in Ancient Egypt. Ancient Assyria and Egyptian Wooden Pin Locks: One early example of locks was discovered in the ruins of Nineveh, the capital of ancient Assyria. These locks evolved into the Egyptian wooden pin lock. The design included a bolt, door fixture, and key. When the key was inserted, pins within the fixture lifted out of drilled holes in the bolt, allowing movement. Removing the key caused the pins to fall part-way into the bolt, preventing further movement. Warded Locks: The warded lock, recognizable even today, existed from antiquity. It features a set of wards (obstacles) inside the lock that only allow the correct key to rotate freely. Warded locks were prevalent in medieval Europe. First All-Metal Locks: Between 870 and 900 CE, English craftsmen developed the first all-metal locks. These locks marked a significant advancement in security. Additionally, it’s said that the key itself was invented by Theodorus of Samos in the 6th century BCE. Roman Locks: Affluent Romans stored valuables in secure locked boxes within their households. They even wore the keys as rings on their fingers, signaling wealth and importance. This practice kept the key handy while safeguarding their treasures. Gothic Locks: Special Gothic locks, dating back to the 17th-18th century (and potentially older), can be found in places like the Beguinage of Lier in Belgium. These locks were often decorated with foliage, surrounding the keyhole in a V-shape. The evolution of locks reflects both craftsmanship and ingenuity, from ancient wooden mechanisms to intricate metal designs.
