An Introduction to the History of Locks

Locks and keys were known long before the birth of Christ. They are mentioned frequently in the Old Testament and in mythology. In the Book of Nehemiah, chapter 3, it is stated that when repairing the old gates of the City of Jerusalem - probably in 445 B.C. - they "set up the doors thereof, and the locks thereof, and the bars thereof." At this time, locks were made of wood. They were large and crude in design; yet their principle of operation was the forerunner of the modern pin-tumbler locks of today.

As locksmiths and metal workers became proficient in their craft, they were invited to make locks and keys for the Royal Courts and for the churches and cathedrals of Europe. They excelled in elaborate and high and highly detailed ornamentation - often adapted to the religious theme.
