Locksmithing is one of the oldest professions in the world; and for good reason. For as long as people have had valuables, they have needed ways to protect them. From wooden pin locks in ancient Egypt to today's biometric security systems, the story of locks is the story of human ingenuity in the face of theft and insecurity. ## Where Were Locks First Invented? Over 4,000 years ago, the Egyptians invented what is widely considered the world's first lock. Made entirely from wood, this early mechanism used a set of falling pins to block a wooden bolt. A large, cumbersome wooden key lifted the pins and slid the bolt open. Though primitive, this system introduced the two foundational ideas still used today: mechanical pin-based security and a unique key to control access. ## How Did Locks Evolve in Ancient Rome? By the time of the Roman Empire, locks had become more refined. Wealthy Romans stored their valuables in secure boxes and wore their keys as rings, not just for convenience, but as a symbol of status. Owning a lock signaled prosperity and something worth protecting. Roman metalwork pushed lock design forward, making mechanisms smaller and more portable than anything the Egyptians had produced. ## When Did Metal Locks First Appear? The earliest metal locks are believed to have been crafted in England around 870 AD. Stronger and more complex than their wooden ancestors, these devices marked a turning point in both security and craftsmanship. For centuries afterward, locksmiths were also skilled metalworkers, forging each component of a lock by hand. A tradition that continued well into the industrial age. ## How Did the American Lock Industry Begin? In the 1700s, locksmithing took off in the United States. As the new Republic grew, so did the demand for secure doors, safes, and storage. Between 1774 and 1920, over 3,000 lock-related patents were filed by American inventors. Notable breakthroughs include Linus Yale's domestic lock, the ancestor of today's pin tumbler, and Walter Schlage's cylindrical lock, a design still widely used in homes and businesses today. ## What Does Modern Locksmithing Look Like?
