combination locks
No key needed
Combination locks are locks that open when a sequence of numbers or symbols is entered correctly, rather than requiring a physical key.
The typical design has a rotating dial that must be turned to specific positions in a particular order: She spun through the combination on her locker.
The term also covers digital keypads and padlocks with numbered wheels.
