Padlocks are portable locks with a shackle that may be passed through an opening (such as a chain link, or hasp staple) to prevent use, theft, vandalism or harm.

There are padlocks dating to the Roman Era, 500 BC – 300 AD. They were known in early times by merchants traveling the ancient trade routes to Asia, including China.

Padlocks have been used in China since the late Eastern Han Dynasty (25–220 AD). According to Hong-Sen Yan, director of the National Science and Technology Museum, early Chinese padlocks were mainly “key-operated locks with splitting springs, and partially keyless letter combination locks”. Padlocks were made from bronze, brass, silver, and other materials. The use of bronze was more prevalent for the early Chinese padlocks.

Padlocks with spring tine mechanisms have been found in York, England, at the Jorvik Viking settlement, dated 850 AD. During this period between 850 AD and the early 1000 AD was when the name ‘padlock’ was coined. It was contrived during this period to initially hold livestock within its quarters of the paddock, whereby the word pad was derived and applied to form the current word.
