The locking device includes a key having a cylindrical shaft in which a guide groove is formed in the axial direction, and a cylinder lock which includes an outer cylinder, an inner cylinder, a locking bar and a tumbler, the inner cylinder has an inner cylinder main body rotatably accommodated in the outer cylinder, a rod fixed to the inner cylinder main body, and a key insertion slot, the locking bar is interposed between the inner cylinder main body and the outer cylinder and prevents the rotation of the inner cylinder by engaging and disengagingly locking the inner cylinder main body and the outer cylinder, and the tumbler has a guide convex portion engageably and detachably engaged with the key groove, and an inner concave portion rotatably received in the inner cylinder and dropping the locking bar.

A magnetic lock has a barrel and keyway, the barrel when rotated unlocking the lock. Locking element cavities each contain a moveable locking element such as a ball, movable in response to a magnetic field applied by a magnetic key. A locking bar is movable between a locked position and an unlocked position. The locking bar has coded projections which extend into the respective locking element cavities when the locking bar moves from the locked position to the unlocked position. A code plate is shaped in registration with the coded projections. When the locking bar is in the locked position the code plate and the coded projections form a substantially uninterrupted surface. The locking elements prevent movement of the locking bar from the locked position to the unlocked position except when magnetically moved to a coded position.

A key blank for manufacturing a key for a disk cylinder having rotatable disk tumblers has a key shaft that extends along a longitudinal axis. The key shaft further has a plurality of notches that extend transversely to the longitudinal axis, that extend at equal spacings from one another, and that have the same depth. In a key, these notches may form chamfers of drive slopes for driving the disk tumblers.

A portable device executes wireless communication with an in-vehicle device in a vehicle to thereby permit the in-vehicle device to perform control relating to locking or unlocking of a door in the vehicle. The portable device includes a circuit board on which a function for executing control is mounted, a housing, and a side cover. The housing is achieved by combining an upper case and a lower case configured to separate in an up and down direction that is a direction orthogonal to the circuit board. The side cover is attached to a side surface on an outside of the housing to bring the upper case and the lower case into close contact with each other.

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.

Locking systems allow for the unlocking and locking of, e.g., doors, containers, and enclosures. Lock cylinders are coded to specific keys, and often there is a desire to have a key be able to access a subset of lock cylinders. Keys are coded using bitting to gain access to specific lock cylinders. It is with respect to these and other general considerations that embodiments have been described.

A lock operating device (100) configured to be retrofitted on an electromechanical lock (200) having a key-receiving portion (210) is provided. The lock operating device (100) comprises a maneuver knob (110) and a key blade (120) being operably connected to the maneuver knob (110) and being insertable in said key-receiving portion (210) of the electromechanical lock (200), and circuitry (130) which includes wireless communication means (132) arranged to wirelessly receive authentication information, and which circuitry (130) is arranged to communicate the received authentication information to the electromechanical lock (200) via the inserted key blade (120). The lock operating device (100) thereby allows conversion of the electromechanical lock (200) from a first operating mode, in which the electromechanical lock (200) can be operated by a programmable physical key receivable in said key-receiving portion (210), to a second operating mode in which the electromechanical lock (200) is arranged to receive said authentication information wirelessly and be operated by the maneuver knob (110).

A tumbler pin lock includes one or two auxiliary locking mechanisms including an auxiliary locking pin, and an auxiliary blocking component to provide enhance locking in addition to the locking provided by the tumbler pins so that the lock remains locked even if the tumblers are picked or bumped into their unlocked positions. A cylinder lock is provided with an auxiliary locking pin which projects into the keyway, which, with the proper key, is slid forward with a mobile device into an area in the lock housing where an auxiliary groove allows the cylinder plug to turn. The second locking component, which is approximately rectangular similarly has a post that is moved forward with the insertion of the proper key into an annular groove allowing the cylinder plug to turn.

The invention relates to a mechanical system for blocking and opening in a lock that can be actuated via a key with a linear movement, without rotation, which does not therefore require a rotation of the key to actuate the opening mechanism, not including any kind of cylinder system. Same comprises two complete parts, as shown in FIG. 1, a special key (1) and the system comprising the set of parts forming the lock. Upon introducing the key with a simple linear movement, and without needing to rotate same, the different mechanical actions are triggered that permit the unblocking of the lock, such that the individual notches of the key press on readers (2), which are to be calibrated, and, only if the position is correct, the mechanisms permitting the opening are released. Same is particularly applicable in embedded locks for all door configurations.

A two-dimensionally driven lock and key are provided. The two-dimensionally driven lock has a lock core having sliders and a block. The sliders are movably and rotatably mounted in the lock core. Each slider has a recessed portion and a non-circular positioning portion. The block has protrusion portions selectively received in the recessed portions. The key has positioning dimples identical to the positioning portion in shape. When the key is inserted into the lock core, the positioning portions match to the positioning dimples respectively and the protrusion portions face to the recessed portions. An unlocking method includes inserting a key into a lock core to make the recessed portion and the protrusion portion face and align to each other by moving and rotating the sliders. Therefore, a location of the recessed portion can vary on the slider in two dimensions, and thus making ulocking very difficult.
