A lock assembly for a door, the lock assembly including a first magnetic field sensor and a second magnetic field sensor. The first magnetic field sensor and the second magnetic field sensor are moveable with respect to the door to determine an open position of the door, a close position of the door, and a fault condition. In one embodiment, the first magnetic field sensor and the second magnetic field sensor move with respect to the door as the door moves from the open position and the close position. The first magnetic field sensor is spaced from the second magnetic field sensor such that each of the first and second magnetic field sensors detects a different value of magnetic field intensity. A controller determines a position of the door with respect to a door frame using signals provided by the first and second magnetic field sensors.

A lock assembly comprising: a cradle configured to support at least part of a lock cylinder; a lock body configured to retain the cradle at least partly inside a space provided in the lock body; and a first fastener for fastening the lock cylinder to the cradle. A method for installing a lock assembly in a door or window comprising: attaching a lock cylinder to a cradle using a first fastener; and attaching the cradle to a lock body. A lock assembly comprising: a lock body having a longitudinal axis; a first bolt provided at least in part inside the lock body and configured to move substantially parallel to the longitudinal axis and between a first retracted position and a first extended position; an actuator configured to move the first bolt between the first retracted position and the first extended position; and a locking bar configured in an unlocked position to allow the first bolt to move to or from the first extended position and in a locked position to engage with the first bolt preventing the first bolt from moving from the first extended position.

A lock and method of use for securing and un-securing first and second articles, the lock comprises a first element rotationally engaged about a longitudinal axis to the first article, an extension beam rotationally engaged about a lengthwise axis to the first article, the lengthwise and longitudinal axes are coincident, the beam has structure to rotationally engage and disengage the first element. Also included is structure to engage and disengage the second article that is driven from the beam, wherein operationally the beam rotationally engages the first element and the extension beam engages and disengages the first and second articles, resulting in the beam always being able to engage and disengage the first and second articles and the first element only having an ability to engage and disengage the first and second articles when the first element and the beam are rotationally engaged to one another.

A closing system for a door or hatch of a motor vehicle includes: a bearing piece and a cylinder lock situated on the bearing piece, the cylinder lock having a cylinder bushing and a cylinder core; and a locking clamp which is held on the bearing piece, engages the cylinder bushing from behind and has a holding lug which is oriented parallel to the cylinder bushing, a fastening screw passing through the holding lug, and the tip of the screw lying in a receiving depression in the cylinder bushing in order to preload the locking clamp against the cylinder bushing. A protective element rests on an outer side of the bearing piece and has at least one retaining lug which is oriented parallel to the cylinder bushing, and the fastening screw also passes through the retaining lug.

A deadbolt lock assembly is disclosed. The deadbolt lock assembly includes an exterior lock mechanism and an interior lock mechanism mechanically connected through a bored hole in a door. The exterior portion of the lock assembly includes a reinforced chassis with a reinforced lock cylinder bore and an anti-rotation arm to enhance the lock's resistance to attack. The interior portion includes a thumbturn that is physically connected to the gearbox frame for robustness and includes stabilizing detents to improve the user feel. The gearbox frame and mounting bracket are connected with a single screw and spring-loaded latch for ease of assembly.

Provided is a lock device for an opening/closing body, the device having a reduced number of parts and enabling a key cylinder to be removed with greater ease. The lock device comprises a lock part, a lock member which is operated via a manipulation member, a base member, and a key cylinder, wherein: the manipulation member comprises a cylinder housing part; the base member comprises a cylinder arrangement space in which the cylinder housing part is arranged, a wall part located at the tip side of the manipulation member, and an opening formed in the wall part; the key cylinder comprises a key plate; the key plate comprises a pressing surface; and the pressing surface is exposed inside the cylinder arrangement space and disposed further to the base end part side of the manipulation member than the edge part of the opening in the wall part.

An exemplary lock apparatus includes a housing and a plug assembly rotatably mounted in the housing. The plug assembly includes a tumbler assembly operable to selectively prevent rotation of the plug assembly relative to the housing and a retention mechanism operable to selectively prevent removal of the plug assembly from the housing. A system including the lock apparatus may include a change key configured to actuate the tumbler assembly without actuating the retention mechanism and/or a control key configured to actuate both the tumbler assembly and the retention mechanism.

A door lock assembly with interchangeable lock cylinders is described. The door lock assembly includes a handle. The handle includes a lock cylinder passage to receive a push to lock cylinder or a key to lock cylinder. A spring plate includes a bolt opening to position the lock cylinder. The spring plate further includes a side bolt opening. A side bolt is configured to selectively enter the side bolt opening of the spring plate to lock the lock cylinder and to selectively withdraw the side bolt from the side bolt opening of the spring plate to unlock the lock cylinder.

A housing configured to accept a rekeyable lock core for use in lockable enclosures. The housing is configured to use a lock core that is designed for deadbolt and door lever/knob operation. The housing allows a rekeyable lock cylinder to be used in one's home as well as other enclosure enclosures. A common key may therefore be used for all devices as the lock core is of a rekeyable design.

A lock and method of use for securing and un-securing first and second articles, the lock comprises a first element rotationally engaged about a longitudinal axis to the first article, an extension beam rotationally engaged about a lengthwise axis to the first article, the lengthwise and longitudinal axes are coincident, the beam has structure to rotationally engage and disengage the first element. Also included is structure to engage and disengage the second article that is driven from the beam, wherein operationally the beam rotationally engages the first element and the extension beam engages and disengages the first and second articles, resulting in the beam always being able to engage and disengage the first and second articles and the first element only having an ability to engage and disengage the first and second articles when the first element and the beam are rotationally engaged to one another.
