The Japanese language uses different words for 'unlock' depending on whether you are dealing with a physical lock, a technical restriction or a metaphorical knot. 開ける is a common way to say 'to open', but when used in the context of a lock, it is often used as a shorthand for the act of unlocking. 解錠する is used for the mechanical act of unlocking a physical object, while 解除する is used for 'unlocking' in the sense of disabling a restriction, such as a password or a screen lock. Finally, 解く is used when 'unlocking' refers to untying a knot or solving a puzzle.
Which one should you use?
開ける is a general term for opening or unlocking, whereas 解錠する is a technical, formal term specifically for the mechanical act of using a key to unlock a physical lock. 解除する differs by focusing on disabling settings or restrictions rather than physical mechanisms. 解く should not be used for a door lock, but rather for untying something or solving a problem.
