Did you know that the oldest known lock is over 4,000 years old?

In the Khorsabad palace ruins in Nineveh the lock was discovered. This is the oldest known lock and the humble beginning of what we refer to as a pin tumbler style of lock. The lock used a large wooden bolt to secure a door. It had a slot with multiple holes in it and these holes were filled with wooden pegs to prevent it from being opened.

The oldest version of this lock used with a key dates back to around 704BC. The hole that was left for a hand to enter to pull pins out was reduced in size and a large wooden key was entered instead to lift the pins. This was also discovered in Khorsabad, in the palace of Sargon.
