A programmable combination lock with keyed lock override is disclosed. The lock employs a stack of rings and dial wheels, with a mechanism for coupling and decoupling the rings and dial wheels. A user can program a custom code by unlocking the combination and rotating the inner and outer dial wheels until the desired code is indicated, and then locking the combination lock to set the code. A keyed lock with a master key couples to the combination lock and can override a combination lock in the locked state. The keyed lock allows multiple keys to lock and unlock the combination lock. In the event that a user loses the master key, the user can use the second key to create a new lock combination to operate the lock, yet render the lost master key inoperable.

Disclosed is an improved password lock, comprising a housing, a lock case, a password box, and a tongue; the housing is composed of a shell and a panel; the panel is fixed on the top surface of the shell to form an accommodating cavity of the housing; the middle part of the lock case is rotatably sleeved at one side of the housing; the password box is installed in the accommodating cavity of the housing, and the password box is cooperatively linked with the lock case; and the tongue is fixedly sleeved on a penetrating end, penetrating through the housing, of the lock case. The lock case can drive a slide block in the password box to move horizontally for changing a password, and therefore the operation is convenient.

A lock including a body which houses a combination lock, which is releasable by the selection of a set code, the code being selectable by the movement of one or more dials, the or each dial including a first part which is manipulable by a user, wherein the lock includes a code finding device to enable the set code to be identified, the code finding device including a code finding member associated with the or each dial, the or each code finding member being engageable with a second part of the respective dial, to identify a position of the dial which corresponds with a digit of the set code, wherein the second part of each dial is moveable relative to the first part of the respective dial and relative to the respective code finding member between a disengaged position and an engaged position, and wherein the or each code finding member is fixed substantially stationary relative to the body.

A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.

The invention relates to a locking device (1) for containers, doors, cabinets, furniture, or the like, which locking device has a lock plate (4), on which a combination lock (7), which has setting wheels (9), and a secondary lock (8) are arranged, and a stator (3), in relation to which the lock plate (4) having the combination lock (7) and the secondary lock (8) is rotatably arranged, the lock plate (4) having the combination lock (7) arranged thereon and with the secondary lock (8) arranged thereon being able to freely rotate 360 degrees relative to the stator (3) in the locked state of the locking device (1). In order to indicate opening of the locking device (1) by actuation of the secondary lock (8) to a person possessing the opening code of the combination lock (7), according to the invention, when the locking device (1) is opened by means of the secondary lock (8), the setting wheels (9) and coupling hubs (11) of the combination lock (7), which coupling hubs are associated with the setting wheels and can be axially moved relative to the setting wheels, can be uncoupled and an opening code of the combination lock (7) can be reset from an opening code set by means of the secondary lock (8) at the time of the opening of the locking device (1) to a specified factory code.

Password-retrieving-apparatus for coded lock, a movable adjusting rod is arranged in the lock body; a small spring is arranged between the adjusting rod and a lock cover; the adjusting rod is provided with a protruding point; an inner wheel is provided with an avoidance clamping slot and a limit; a lock cylinder is driven to rotate under the rotation of a spare key; the lock cylinder is engaged with a bump on a toggling disk for driving the inner wheel to rotate in a staggered manner; the lock body moves relatively under the action of a big spring; the adjusting rod moves inwards under the action of the small spring; and the toggling disk is rotated to drive the inner wheel to rotate; the protruding point on the adjusting rod and the limit in the inner wheel are clamped.
