(57) A key cutting device (20), for replacement keys, having a key blank support member
(30), a lever-actuated shearing punch (25) for the key blank, and a depth-gauging
stop (33) for the support member (30); the shearing punch (25) is formed to provide
an optional two-step (44, 46) cut on the key with a control stop (49) for limiting
the stroke of the punch to one step or two steps, as desired, for creating different
cuts on the key blank; a locking device (63) automatically moves into locking position
with respect to the yieldably-actuated support member (30) to prevent its displacement
when the operating lever (37) is manipulated for the key cutting operation.
