A method of controlling a lock mechanism of an active door includes transiting an access controller of the lock mechanism to an authorized access mode and transitioning the access controller from the authorized access mode to an entry mode. Transitioning the access controller to the authorized access mode is in response to an authorized user being sensed approaching the active door from an exterior side of the active door or in response to input on a remote device. In the authorized access mode, an exterior handle of the active door is decoupled from a main latch of the lock mechanism. Transitioning the access controller to the entry mode is in response to sensed contact with the exterior handle. In the entry mode, the exterior handle is capable of rotating to transition the access controller to an unlocked mode in which the exterior handle is operably coupled to the main latch.

A motor vehicle lock having a positioning element, especially a control shaft, and a drive unit for moving the positioning element, wherein the drive unit has a rotor and a stator, the stator having a coil arrangement and at least two magnetically conducting poles associated with the coil arrangement for conducting the magnetic field created by the coil arrangement. It is proposed that the poles each time form, with the rotor, an axial air gap relative to the geometrical rotor axis, possibly in dependence on the rotor position, and a first segment of the coil arrangement with at least two coils and a second segment of the coil arrangement with at least two coils are arranged along the geometrical rotor axis on opposite sides of the rotor.

A lock assembly, comprising: a drive hub configured to be rotated in a first angular direction; a latch having a latch engaged position; a lock having a locked position; a first locking member configured such that, when the lock is in the locked position, the first locking member retains the latch in the latch engaged position; and a second locking member configured such that, when the lock is in the locked position, the second locking member prevents the drive hub from rotating in the first angular direction.

A door latch assembly includes a housing; a bolt configured to the extend from the housing in a first direction and retract into the housing in a second direction; a handle connected to the bolt; a lockable, blocking member configured to prevent movement of the bolt; a controller configured to place the door latch assembly into an overlock mode; an actuator in communication with the controller, the actuator configured to prevent movement of the bolt in the overlock mode.

A handle set includes a main body that has a handle and a faceplate positioned around the handle, the faceplate having a toggle aperture. The handle set includes a locking mechanism that includes a locking piece that has a locking notch. The locking mechanism includes a toggle positioned within a toggle housing, the toggle being movable relative to the toggle housing. The toggle includes a toggle tail configured to be received into the locking notch. The toggle includes a toggle head removably attached to the toggle tail, the toggle head being at least one of a privacy attachment button and a passage attachment button. At least a portion of the privacy attachment button extends from the toggle aperture and beyond the faceplate. The passage attachment button interfaces with the toggle housing to prevent relative movement between the passage attachment button and the toggle housing.

A modularized electric latch control device includes a mounting seat and a locking cap device pivotably mounted to the mounting seat and pivotable relative to the mounting seat between a closure position and a non-closure position. Optionally mounted to the electric latch control device are a stopper, a closure member, a locking latch restraining frame, a first escutcheon, and a second escutcheon. The electric latch control device is selectively assembled into a first mode (including the first escutcheon), a second mode (including the closure member, the stopper, and the second escutcheon), or a third mode (including the locking latch restraining frame, the stopper, and the second escutcheon) for cooperating with a cylindrical latch device, a first box type latch device, or a second box type latch device.

A lock with an emergency unlocking feature includes a latch bolt, a top rotation member, a restriction plate and a driving member. The driving member is connected to the deadbolt. When the top rotation member is rotated from a close position to an open position while the lock is locked, a restriction member drives the restriction plate to press a resilient unit. The restriction plate is moved to disengage the engaging member on the restriction plate from the second notch of the driving member. The guide slot of the transmission plate pulls the second guide member to move the deadbolt to the unlocked position, and the latch bolt moves to the open position. When in an emergency situation, the user rotates the handle to retract both of the deadbolt and the latch bolt without using a key to unlock the deadbolt to save time.
