A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

A multifunction hub core for a mortise lock comprises a mortise lock body having a deadbolt operable by a first control member on the outside of a door and a second control member on the inside of the door, and a deadbolt arm with slots for receiving a hub core. The deadbolt arm is rotatable inside the mortise lock body to move the deadbolt between retracted and projected positions. The hub core disposed in the deadbolt arm comprises projections allowing it to fit in the deadbolt arm slots in one of two positions. The first position allows the second control member to move the deadbolt between retracted and projected positions and is known as the standard function. The second position allows the second control member to retract the deadbolt from a projected position, but cannot project the deadbolt from a retracted position, and is known as the classroom function.

Door lock

A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

Door lock assembly

A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

Door lock assembly with waggle reduction

An electronic door lock system includes a gasket system for protecting electrical and mechanical components from exterior water and air. A lock portion may include a gasket, a circuit board, and a plate disposed between a first and second housing. The gasket includes an L-shaped perimeter that wraps around a first side and perimeter edge of the circuit board. The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.

Door lock assembly including weatherization

A hook bolt for a latch assembly includes a hook that deploys laterally from a deadbolt when the deadbolt is moved to an extended position. When the deadbolt is actuated, the hook automatically deploys perpendicular to the deadbolt movement to an engaged position within a corresponding opening in a door jamb to secure the door.
