locking mechanisms
Devices preventing entry
Locking mechanisms are devices or systems that secure something in position or prevent unauthorized access.
The term spans physical hardware—deadbolts, padlocks, latches—and abstract systems like software authentication.
Any arrangement that holds something fixed or restricted qualifies: The seatbelt's locking mechanism engaged on impact.
In technical contexts, the phrase often describes how components fasten together: The locking mechanism on the camera lens.
