Abstract
A shielded pushbutton lock that includes housing that supports a lock cylinder connected to a key operated pushbutton. The pushbutton is shielded by way of a rotatable collar that extends over the pushbutton and shields the pushbutton, so that a thief may not defeat the pushbutton lock mechanism by attempting to rotate the pushbutton in order to allow operation of the latch mechanism.
