To unlock something means to remove or disable a lock that's keeping it closed. It can also mean to reveal information or solve a problem.
When we think of unlocking something, we often think about a physical object like a door or a padlock, but the word is used in other contexts too. For example, you might need to unlock your phone or computer by entering a password or code. This means that you're not just opening a physical lock, but also giving access to the device's internal systems.
The act of unlocking something.
To undo or open a lock or something locked by, for example, turning a key, or selecting a combination.
Example: I unlocked the door and walked in.
