tumbler lock
Keyed cylinder security
A tumbler lock is a lock mechanism in which pins, discs, or levers (called tumblers) must be moved to specific positions before the lock will open.
When the correct key is inserted, it pushes each tumbler to the precise height needed to align with the shear line, allowing the cylinder to rotate.
Most household door locks and padlocks use some form of tumbler mechanism.
