'lockpick' originates from the combination of 'lock' and 'pick', where 'lock' refers to a fastening device and 'pick' refers to a tool used for opening.

'lockpick' evolved from the Old English 'loc' meaning 'fastening' and 'pic' meaning 'pointed tool'.

Initially, it meant 'a tool for opening locks', and this meaning has largely remained the same in modern usage.
