Īffluent Romans often kept their valuables in secure locked boxes within their households, and wore the keys as rings on their fingers. It is also said that the key was invented by Theodorus of Samos in the 6th century BC. The first all-metal locks appeared between the years 870 and 900, and are attributed to English craftsmen.

When the key was removed, the pins fell part-way into the bolt, preventing movement. When the key was inserted, pins within the fixture were lifted out of drilled holes within the bolt, allowing it to move. Locks such as this were developed into the Egyptian wooden pin lock, which consisted of a bolt, door fixture or attachment, and key. Locks have been in use for over 6000 years, with one early example discovered in the ruins of Nineveh, the capital of ancient Assyria.
