By operationally mounting a plurality of wafers or plates forming tumblers in an independent, separate, substantially closed container, and cooperatively mounting the plate tumbler container with a cylinder forming member, a unique cylinder lock system is attained which is easily and inexpensively manufactured, as well as quickly and easily re-keyed whenever desired. In the preferred embodiment, all of the plate tumblers which are desired for the particular lock construction are mounted in the substantially closed container, with each plate tumbler having the requisite spring means associated therewith. In addition, the plate tumbler holding container incorporates one aperture for each plate tumbler which allows the slot engaging fin of each tumbler to extend outwardly from the container for locking and unlocking association with the housing.
