A finger operated electro-optical lock system in which an optical keyboard having at least one zone indicated thereon is illuminated by ambient energy until touched by a finger of the human hand blocking the radiant energy passing through the zone. A counter is thus enabled to cycle a numeric display. When the first digit of the combination appears in the display, the finger is lifted and reapplied until the second digit of the combination is displayed. The process is repeated until each digit of the combination has been displayed.
