An inside operator for a lock having a spring biased bolt includes a shaft which can be immobilized, thus preventing longitudinal bolt motion, by applying force in the axial direction to the handle of the operator. The operator shaft is telescopic to ensure that the coupling of the operator shaft to the bolt is not interrupted as the operator is switched between operational modes.

Combination lockout/holdback apparatus

An actuator for a lock is provided with a operating handle which may be easily removed through the use of a special key and may also be reinstalled without the use of the special key or tools. The actuator may be 'rekeyed' as necessary to maintain security and removal of the handle will lock the actuator.
