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