A lock assembly for use with a latch movable from an extended position to a retracted position, and the lock assembly includes an interior assembly and an exterior assembly. The interior assembly includes an interior handle manually movable to retract the latch and a locking member manually operable such that the locking member is movable from an unlocked position to a locked position. The exterior assembly includes an exterior handle manually operable to retract the latch when the locking member is in the unlocked position and inoperable to retract the latch when the locking member is in the locked position. The exterior assembly further includes a biasing member that biases the locking member toward the unlocked position. When the locking member is in the locked position, movement of the interior handle to retract the latch causes the biasing member to move the locking member to the unlocked position.
