Home Security Doors UK: A Short History Of Locks

Home security doors UK wide play an important part in keeping people, possessions and properties safe from intruders, thieves and those who mean us harm. But even the strongest of steel security doors is of no use without a powerful locking system in place. Locks are incredibly important devices in security. In fact, it could be argued that they are the most important and basic element of any security measure – a device used to limit access to a space. So, here is a very brief history of the lock and how locks have evolved to where they are at today.

Locks, in some shape or form, have been around for thousands of years. The earliest rudimentary lock and key device was found in Nineveh, the ancient capital of Assyria, which today sits close to Mosul in northern Iraq. But it was the Egyptians who originally developed the pre-cursor of the modern-day pin tumbler lock that we find on many regular and security front doors UK wide today. The major step forward, however, was the Industrial Revolution of the late 18th century that helped bring us the strong materials needed for locks and steel security doors Manchester, England and UK wide.

New technology continues to forward developments in doors for home security. Locks continue to be advanced and now utilise different forms of mechanisms that go way beyond the simple single lock-and-key systems found in previous security systems.
