A locking mechanism in which a series of disks each having a radial hole therein are mounted on the inside of a door. Said disks are connected to dials on the outside of the door which are associated with numbered indicia and rotatable to vary the rotatable and axial positions of the holes in the disks. A locking bolt is slidably mounted on the inside of the door and interconnected to a series of pins which are receivable in the holes in said disks when said holes are aligned therewith. A lever is connected to the locking bolt and operable from outside the door to slidably move the bolt from a locked position to an unlocked position when the dials are set at preselected numbers on the indicia to rotatably align the holes in said disks for reception of the pins.
