IN ONE EMBODIMENT THE AUXILIARY PIN-ACTUATING MEANS IS ACTUATED BY MANUAL MOVEMENT THROUGH A CAMMED SLOT WITHIN THE HANDLE OF THE KEY OR A PRESSURE ACTUATED LEVER MOVES THE PUSH ROD INTO ENGAGEMENT WITH A LOCKING PIN OF THE TUMBLER. IN ANOTHER EMBODIMENT THE INNER TIP OF KEY PROVIDES THE MEANS FOR ENGAGING AND ROTATING THE LOCKING LUG AND A SEPARATE CIRCUMFERENTIALLY SPACED TUMBLER IS PROVIDED IN THE LOCK CYLINDER FOR ACTUATION BY THE SIDE OF THE KEY OR FOR REGISTRY WITH AN APERTURE THROUGH THE SIDE OF THE KEY FOR POSITIONING TO UNLOCK POSITION.
