Introduction • Locks have been widely used in our daily life in the past thousands of years. • It is still a myth concerning the origin of the earliest lock in history. • Cave dwellers learned to put heavy rocks at cave openings to block wild animals and protect their belongings. • The oldest locks paired with a key were wooden locks. • Ancient Egyptians are deemed to use wooden pin tumbler locks no later than 4,000 years.
Introduction • Ancient Chinese metal locks appeared in the Eastern Zhou Dynasty (770-256 BC). • Metal padlocks with thin & flat springs installed inside became popular in the Han Dynasty (206 BC - 220 AD) • Most currently available ancient locks were made in the Qing Dynasty in 18th -19th century, with few recovered from ancient tombs of the Tang Dynasty (619-907 AD). • Most locks made before the Sung Dynasty (960-1279 AD) are lost.

Concluding Remarks Recluse Taishang (Tang Dynasty, 618-906 AD) “Beneath a pine I occasionally came. Upon a rock pillow I comfortably napped. Reckoning no days in the mountains, I did not know the year after the cold winter.” 唐朝(公元618-906年)太上隱者 『偶來松樹下,高枕石頭眠,山中無曆日,寒盡不知年。』
