Abstract
A profiled key for use in an associated cylinder lock provided with a rotatable key plug having a longitudinal keyway. The key has a substantially flat key blade with a longitudinally extending profile groove at a side surface thereof and at least one local recess adjacent to the profile groove. The local recess constitutes a locally expanded portion of the profile groove, and the locally expanded portion of the profile groove has a cross-section with two opposite, non-symmetrical side walls. The local recess will accommodate a blocking element in the lock, and permit full insertion of the key blade into the keyway.
