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.

An anti-lock picking lock device is provided. The lock device features a locking cylinder having an opening configured to receive a drawer. The drawer having a keyway slot on its top surface and is configured to receive a similar shaped key. The drawer is enabled to slide within the clocking cylinder during use. In one position, the keyway slot is not exposed and occluded from any type of tampering. In another positon, the drawer is extended, either manually or via an electronic device, making the keyway slot accessible for operation.

A key or key blank includes a key blade having a first edge, a second edge, and first and second opposed sides. The first edge has one or more edge bittings to elevate and/or rotate one or more tumbler pins of a lock with a vertically-oriented keyway, and one of the opposed sides has one or more side bittings to elevate and/or rotate one or more tumbler pins of a lock with a horizontally-oriented keyway. Side warding surfaces on the key blank are shaped and positioned to minimize the interference of peaks between the skewed bitting cuts on the key. A lock has a keyway configured for the key having edge bittings to elevate and/or rotate one or more tumbler pins of a vertical lock and side bittings to elevate and/or rotate one or more tumbler pins of a horizontal lock.

A cylinder lock includes a housing; a cylinder rotatably provided therein and having first and second ends, the cylinder extending in a longitudinal direction between the first and second ends and including an internal keyway for placing a key corresponding to the lock in the cylinder; a locking mechanism that prevents rotation of the cylinder with respect to the housing when the key is not present in the keyway; a blocking element positioned between the first and second end, and configurable to take a first position wherein the keyway is blocked such that the key cannot be placed in the keyway and a second position wherein the keyway is unblocked such that the key can be placed therein; a configuration device to configure the blocking element in the first or second position, and controllable by wireless communication between the lock and a remote control unit.
