A smart door lock assembly includes a lock cylinder, a lock cylinder mounting block, a driving motor, and a driving control board. A driving gear is arranged on a movable end of the driving motor. The lock cylinder passes through and is mounted in the lock cylinder mounting block. A driven gear coaxial with the lock cylinder is arranged on the lock cylinder mounting block. The driven gear is driven by the driving gear. The driving control board determines whether an external input unlocking command is right and controls the driving motor to unlock the smart door lock assembly when the external input unlocking command is right. The driving motor has a virtual position in a process of driving the driving gear.

A locking mechanism is selectively operable both electronically and mechanically by way of an integrated mechanical lock and motorized lock mechanism. A motorized lock mechanism is incorporated with a mechanical lock to provide for keyless access, while the mechanical lock and key system remains as a back-up. A toggle assembly is selectively positioned either mechanically via a first cam, or electronically via a second cam, both selectively operable independently of each other, without interference from each other, to move the toggle assembly to its unlocked position. A spring biases the toggle assembly to its locked position when the first and second cams are in their locked positions.

Door lock systems and related methods of use are provided. A motor of a door lock system may be placed against a surface of a housing and a bracket may be placed between the motor and a wall of the housing. The motor may be secured in the housing by moving the bracket against the wall of the housing to retain the bracket and apply a force to the motor. A door lock system may include a mounting bracket configured to receive a housing of the door lock system and secure the door housing to an associated door.

An electronic lock assembly includes an exterior assembly, an interior assembly, and a latch having a deadbolt movable between an extended position and a retracted position, the latch being movable in response to rotation of a torque blade. The electronic lock includes a motor within the interior assembly and operable to rotate the torque blade, and a control circuit operatively connected to the motor and configured to selectively actuate the motor. A mortise insert includes a battery subassembly electrically connectable to the control circuit.

A lock indicator and a mechanical lock assembly, comprising: a switch; a transmitter coupled to a power source; and a bolt member moveable between a retracted position and an extended position with respect to the housing, wherein the switch is configured to engage the bolt member and is actuatable by the bolt member to determine the position of the bolt member, and the transmitter is configured to transmit a signal indicative of the position of the bolt member to a remote device.

An electric latch retraction device for vertical rod door latches includes an automatic adjustment feature including a limit switch and a linear sensor, such as a Hall effect sensor, which detects vertical position. A microcontroller monitors the vertical position of a pivoting retraction lever driven at the pivot by a linear driver. The housing for the electric latch retraction device is preferably external to the door and one end of the retraction lever extends into the door to drive a vertical rod door latch mechanism while an opposed end contacts the limit switch to signal that continued driving of the linear driver will begin to drive the vertical rod door latch. The microcontroller determines from the vertical position of the retraction lever when the limit switch is actuated whether the electric latch retraction device is mounted too high or too low.

A locking device (40) including a first module (42) and a second module (44), one of the first module (42) and the second module (44) being attachable to a first face (22a) of a door panel (22) of an enclosure (10) to be locked and the other of the first module (42) and the second module (44) being attachable to a second face (22b) of a door panel (22) of an enclosure (10) to be locked, wherein the locking device (40) includes a mechanical locking mechanism (60) and an electronic locking mechanism (46).

An intelligent door lock system is coupled to a door at a dwelling. A sensor is at the dwelling. The sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the sensor and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to define a safe zone in the dwelling in which an occupant, and a non dwelling occupant third person is allowed into the dwelling.

One embodiment relates to an exit device assembly. The exit device assembly includes a center case, a push pad movably mounted on the center case, and a mechanical case coupled to the center case, wherein the exit device includes an opening. The assembly also includes a sensor aligned with the opening, wherein the sensor is structured to detect a user from a distance through the opening and to generate an output signal in response to detecting the user. The assembly also includes a latch and a latch actuator. The assembly also includes a controller in communication with the sensor and the latch actuator, wherein the controller is structured to transmit an actuating signal in response to receiving the output signal from the sensor, wherein the latch actuator is configured to move the latch from the locked position to the unlocked position in response to the actuating signal.

A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.
