Did You Know? The oldest known lock was in the ruins of the Assyrian Empire in the city of Khorsabad. This key was believed to be created around 704 BC and looks and operates much like the wooden locks of the time. In 1778, Robert Barron perfected the lever tumbler lock. His new tumbler lock required the lever to be lifted to a specific height in order to unlock. Lifting the lever too far was as bad as not lifting it far enough. This made it more secure against intruders and is still currently used today. After a burglary occurred in Portsmouth Dockyard in 1817, the British Government created a competition to produce a more superior lock. The competition was won by Jeremiah Chubb who developed the Chubb detector lock. The lock not only made it difficult for people to pick it, but it would indicate to the locks owner if it had been tampered with. Jeremiah won the competition after a lock picker failed to open it after 3 months.  Three years later, Jeremiah and his brother Charles started up their own lock company, Chubb. Over the next couple of decades, they made vast improvements to the standard lock and key systems. This included using six levers instead of the standard four. They also included a disc that allowed the key to pass through but made it difficult for any lock pickers to see the internal levers. Another major improved was the double-acting pin tumbler lock. The earliest patent for this design was granted in 1805, however, the modern version (still in use today) was invented in 1848 by Linus Yale. His lock design used pins of different lengths to stop the lock from opened without the correct key. In 1861, he invented a smaller flatter key with serrated edges that would move the pins. Both his lock and key designs are still in use today.  Apart from the introduction of electronic chips, and some minor improvements in key design, most locks today are still variants of the designs created by Chubb, Bramah and Yale.
