Abstract
Cylindrical locks and more specifically a set of profile members in combination with a rotatable cylindrical key plug have a longitudinal keyway with a profile corresponding to an associated key. Each profile member is accommodated in an associated cavity in the key plug at a lateral side of the keyway so as to form a lateral part thereof. The profile members have a non-circular cross-section and are non-rotatably mounted in the associated cavities at a location adjacent to the keyway. A portion of each profile member has a profiled surface portion facing inwards toward the opposite lateral side of the keyway, the profiled surface portion having, in a plane being transversal to a longitudinal axis of the key plug, a specific profile section defining a local, lateral part of the keyway. An associated key, and a method to manufacture a cylindrical key plug with such profile members are also disclosed.
