A fun fact about locks is that the very first locks were made of wood! This was over 4000 years ago and the idea of wooden pegs being used to secure doors has been around ever since. The Ancient Egyptians and Romans are responsible for this early form of lock. By the 18th century, locks made of iron were being produced and the designs we know today were developed by the Victorians. Today locks are made of strong, durable metals to ensure that they are secure. Source: History of the Lock.
