Abstract
A key for use in a cylinder lock with a rotatable key plug having a profiled keyway. The key comprises an elongated, substantially flay key blade (120; 120′) having a longitudinal profile groove (122; 122′) extending along at least a portion of the length of the key blade. The groove has an undercut portion (129) adjacent to a ridge portion (128, 128′), the outside of which forms part of a side surface (123; 123′) of the key blade. The undercut portion (129; 129′) of the groove is expanded, at its innermost part adjacent to and inside said ridge portion, into a longitudinally extending pocket (135; 135′).
