A lock includes a lock housing, a cylinder assembly rotatably arranged in the lock housing and a locking keyless assembly connected to the cylinder assembly in a transmission way. The cylinder assembly includes a cylinder core and a tailpiece unit, a first clutch mechanism is provided between the cylinder core and the tailpiece unit, and a second clutch mechanism is provided between the locking keyless assembly and the tailpiece unit. When the second clutch mechanism is engaged, the locking keyless assembly is movable relative to the lock housing in a first direction under a driving of an external force for locking, and the cylinder core and the tailpiece unit rotate along with the locking keyless assembly. When the external force on the locking keyless assembly is withdrawn, the locking keyless assembly moves in an opposite second direction opposite, so that the second clutch mechanism switches to a disengaged state.

A lock cylinder including a plug, a plurality of key followers, a sensor assembly structured to sense positions of the key followers, and a controller in communication with the sensor assembly. The plug includes a keyway and a plurality of plug tumbler shafts. Each of the key followers is movably seated in a corresponding one of the plug tumbler shafts and includes a sensor interface. The sensor assembly includes a plurality of sensors, each of which includes at least one sensing region. Each of the key followers is associated with one of the sensors via an associative link formed between the sensor interface and the corresponding sensing region. The sensors are structured to generate an output signal indicative of the transverse position of the associated key follower, and the controller is structured to select and perform actions based upon the output signals.

A rekeyable lock cylinder with a cylinder body and a plug assembly. The lock cylinder includes a plurality of key followers and a corresponding plurality of racks disposed in the plug assembly. Disengaging the racks from the key followers allows rekeying of the lock cylinder.

An electronic lock includes a latch assembly that has a latch housing and a bolt. The bolt is movable between an extended position and a retracted position. The electronic lock includes a controller connected to a circuit board. The controller is configured to electronically control movement of the bolt between the extended position and the retracted position. The electronic lock includes an exposed conductive touch member. The conductive touch member is in electrical communication with the controller. The electronic lock includes an insulating arrangement positioned between the conductive touch member and the circuit board. The electronic lock includes a housing at least partially surrounding the conductive touch member. The housing is electrically isolated from the conductive touch member by at least a portion of the insulating arrangement.

A puller assembly for use with a lock device is disclosed. The lock device may have an interchangeable core. The puller assembly includes a puller core body having an opening sized to receive at least a portion of an operator actuation assembly of the lock device, a first engagement surface positioned to engage a portion of a rear end of the operator actuation assembly of the lock device, a second engagement surface positioned to engage a portion of a front end of a core assembly of the lock device, and an actuator which is moveable to alter a separation between the first engagement surface and the second engagement surface.

A mechanically reprogrammable cylinder lock includes a magnetic tool to provide reprogramming.

In one form, a cylindrical lockset includes a chassis including a pair of hubs, a pair of drive tubes, a retractor, and a lock control assembly. The lock control assembly has a locked state and an unlocked state. The lock control assembly also has a plurality of movable elements, each having a locking position and an unlocking position. One of the hubs includes a guide channel, and a slider is movably seated in the guide channel. One of the movable elements is associated with the slider, and is configured to move the slider between a lock-indicating position and an unlock-indicating position.

A weather resistant tumbler lock has an elongated body, and defines a longitudinal axis. The lock is interchangeable with another lock having a corresponding asymmetrical perimeter profile with an opening in a top surface sealed with a cap, the other lock having a different rotatable core and a different configuration of tumblers. A drainway provides a channel for water to flow outwardly from the interior of a shell housing, a rotatable core and a keyway within the core, to a drain below the lock. The drain connects to a channel through a lower edge. The core provides an arcuate gap in a lower quadrant adjacent the interior surface of the shell for fluid communication with the drainway. A method includes identifying a substitute tumbler lock with an impermeable outer wall for replacing another lock having an identical outer perimeter profile and a permeable closed opening on its top surface.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.
