1. A lockset apparatus for assembly into a lockset designed for a barrier having opposing first and second sides, the lockset apparatus comprising:
a spindle;
opposing first and second handles configured to mount to the opposing first and second sides, respectively;
first and second opposing locking members for the first and second handles, respectively, each locking member comprising a lock button or key cylinder; and
a spindle coupler;
wherein in the assembled lockset:
the spindle is mounted for translation along an axis of the spindle in a first direction toward the first side and in an opposite second direction toward the second side;
the spindle is operatively and rotationally linked to the latchbolt;
the first locking member is operatively connected to the spindle coupler to selectively slide the spindle coupler into engagement with a first end of the spindle;
the second locking member is operatively connected to a second end of the spindle to selectively translate the spindle, with respect to the lockset, into engagement with the spindle coupler;
the lockset has locked and unlocked states characterized by at least three spatial relationships between the spindle, the spindle coupler, and the assembled lockset, including:
first and second spatial relationships in which the spindle coupler is engaged with the spindle, thereby enabling the first handle to retract and project the latchbolt, wherein in the first spatial relationship the spindle is positioned closer to the first side than the second side, and in the second spatial relationship the spindle is positioned closer to the second side than the first side; and
a third spatial relationship in which the spindle is positioned closer to the second side than the first side, and the spindle coupler is positioned closer to the first side than the second side and is disengaged with the spindle, thereby disabling the first handle from retracting and projecting the latchbolt.
