The key blade () has a cross-sectional profile fitting into said keyway, and a profile groove () extending longitudinally along the key blade. The lock comprises a blocking mechanism with at least one blocking element (), which is movable from a first blocking position, in which first projecting portion () of the cross-sectional profile of the blocking element extends outside the cross-sectional contour of said profile rib, into a second blocking position, in which a second projecting portion () extends outside the contour of the rib and is accommodated in a recess () in the key blade. Hereby a correctly cut key can be fully inserted.
