Primitives

The first wooden lock was discovered in Persia as Khorsabad in security gate in the palace of Sargon II, who reigned from 722 to 705 B.C. In appearance and operation, it was very similar to this wooden cane-tumbler locks. The pegs at the bit end of the key correspond to the bars, or the tumblers, in the bolt. When inserted, the pegs lifted the tumblers so that the bolt could be retracted and the door or gate could opened.
