Abstract
A lock assembly comprises a housing, a handle, and a latch plunger operably connected with the handle. An exterior key lock and interior lock knob have a locked and unlocked position. A lock cam is rotatably and operably connected with the key lock and interior lock knob for rotation therewith. A crank arm of the lock cam is operatively coupled with a deadbolt lock movably mounted in the housing for shifting between a locked position and an unlocked position. The deadbolt lock is also operably coupled with a motor, wherein a motor cam clutch is operably coupled with the motor and operably interposed between the lock cam and the motor, wherein the motor cam clutch allows rotation of the lock cam between the locked and unlocked positions without rotating the motor cam clutch or a motor shaft of the motor.
