A key, comprising: a key head; and a key shank (10), characterized in that the key shank (10) includes a torsion section (20) that is formed, in particular cold formed, along a longitudinal axis (L) at least in sections, wherein the key shank (10) includes a base cross-section (26) in a transition portion to the torsion section (20), wherein a cross-section (30) of the key shank (10) protrudes at least in sections beyond the base cross-section (26) in the torsion section (20) in a direction towards the key tip (70).

An electromechanical locking system includes one or more moveable locking elements and one or more actuators configured to move each of the one or more moveable locking elements between positions. The system includes a receptacle configured to receive a key, a sensor, a processor; and a computer-readable storage medium. The processor causes the sensor to scan the key and detect one or more features of the key, identify a first code that corresponds to the detected features of the key, and apply one or more functions to the first code to yield a second code. The second code includes one or more characters that each character corresponds to one of the plurality of positions. The processor causes the one or more actuators to move the one or more movable locking elements to the positions that correspond to the one or more characters of the second code.

An exemplary system includes a mechanical key and an access control device. The access control device includes a housing defining a keyway that has a fixed position within the housing. The access control device further includes a root depth sensor assembly, an insertion depth sensor assembly, a control assembly in communication with the sensor assemblies, and an electronic lock device. The control assembly is configured to determine the bitting code of the mechanical key based upon information received from the sensor assemblies, to compare the bitting code of the mechanical key to a lock/unlock bitting code; and to transmit a lock/unlock command in response to the bitting code matching the lock/unlock bitting code. The electronic lock device is configured to transition between a locked state and an unlocked state in response to receiving the lock/unlock command and without requiring rotation of the mechanical key.

A locking system comprises a lock cylinder which has a cylinder housing, a cylinder core rotatably supported in the cylinder housing and having a keyway, and has a plurality of tumblers which partly project into the keyway, and which furthermore comprises a key which has a key bow and a key shaft which has a shaft profile for acting on the tumblers. An abutment section is formed at the key shaft between the key bow and the shaft profile, said abutment section having an abutment profile having at least one projection and an undercut formed between the projection and the shaft profile. The lock cylinder furthermore comprises a movable counter-abutment. In this respect, the abutment section of the key and the movable counter-abutment of the lock cylinder are arranged and configured such that, on an introduction of the key into the keyway, the abutment section abuts the movable counter-abutment with at least one abutment surface within the keyway and in so doing forms the only active abutment formed at the key for limiting the introduction of the key into the keyway to a correct axial introduction depth.

In an approach, a hybrid security key comprises at least one physical face on a first side of a key comprising a key groove cut and a barcode coupled to a top surface of the physical face; and at least one logical face on a second side of the key comprising a surface insert overlaying a conductive film, wherein the conductive film includes at least one contact point, at least one conductive trace, and a smart chip.

An arrangement and a method for an electromagnetic padlock (10) are disclosed. A handheld unit (30), which is movably connected via a connector member to a lock fitting (50) to be locked by a padlock (10), is removably attached to a padlock (10) during unlocking and locking. When the padlock (10) is locked, a magnetic sensor (44) of the electronic key (40) detects a change in detected magnetic flux from the attached magnet (31), representing a verification that the padlock has both been locked and locked at a correct location. Incorrect locking procedure, or locking at incorrect locations may generate warnings.

The present invention relates to an electromechanical lock assembly (1) comprising a lock body (15), a lock core (17), a lock bolt operating member (19), and an electronic access control device. The electromechanical lock assembly further comprises an annular element (27) which is rotatably and axially displaceably mounted on said lock core (17), a coupling device (25) arranged to communicate with said electronic access control device and, upon the insertion of an appropriate key (65) in a key receptacle (37) of the lock core (17), rotationally lock the annular element (27) to the lock core (17), thereby enabling rotation of the lock core (17) in a first direction and thereby enabling unlocking of a lock (3) with said appropriate key (65), and a blocking arrangement (63) arranged to prevent unauthorized unlocking of said lock (3).

A locking key for changing a locked state by being inserted into a key box includes a first base including a metal complex and in which a first pattern groove is formed, and a first pattern provided in the first pattern groove and including a conductive material.

A dual authentication system of an electronic locking device using an electronic key according to an exemplary embodiment of the present invention includes a receiving unit that receives UID data pre-stored in the electronic key and encoding data generated by an input of a button provided in the electronic key, when a terminal portion provided in a key head of the electronic key is in electrical contact with a data communication unit of the electronic locking device; an authentication unit that performs dual authentication based on the UID data and the encoding data; and a command unit that commands the unlocking of the electronic locking device when the dual authentication on the UID data and the encoding data is successfully performed.

An apparatus for selectably unlocking a door comprises a base adapted to be mounted within a door, an outer cylinder selectably rotatable relative to the base, the outer cylinder having an central bore therethrough and an inner cylinder selectably rotatably received within the inner bore of the outer cylinder. The inner cylinder has a key slot therethrough and is adapted to unlock a door upon rotation of the inner cylinder. The apparatus further includes a plurality of tumblers extending between the inner and outer sleeves alignable upon insertion of a specific key within the key slot so as to permit rotation of the inner cylinder within the central bore a means for identifying a key inserted within the key slot as an authorized key and a latch operable to selectably couple the outer cylinder to the base wherein the latch uncouples the outer cylinder from the base when an authorized key is located within the key slot.
