A lock system is the complete mechanism of a lock, including all its internal components—pins, tumblers, cylinders, and springs—that work together to secure and release.
The term also refers to a coordinated series of canal locks that raise or lower vessels through changes in elevation: The Panama Canal's lock system moves ships between oceans.
