1. In a locking mechanism having an unlocked position and a locked position, the locking mechanism comprising: a) a first handle;b) a first rose attached to the first handle with the first handle adapted for rotational movement relative to the first rose:c) a first longitudinal slot in the first rose extending through a width of the first rose, and parallel to a longitudinal axis defined by the locking mechanism;d) a locking cartridge cylinder at least partially contained within at least the first handle or the first rose; and a locking tab operably connected to the locking cartridge cylinder adapted for movement that is at least partially perpendicular to the longitudinal axis: (1) at least partially into at least the first longitudinal slot in the first rose in a locked position; and (2) completely out of the first longitudinal slot in the first rose in an unlocked position, and a second longitudinal slot in the first handle, wherein the first longitudinal slot in the first rose is alignable with the second longitudinal slot in the first handle. 2. The locking mechanism of claim 1, wherein the locking tab is biased to be at least partially retained within a cavity defined the locking cartridge cylinder in the unlocked position. 3. The locking mechanism of claim 1, further comprising a first longitudinal slot in the first handle and a first longitudinal fin on an exterior surface of the locking cartridge cylinder adapted to seat within at least a portion of the first longitudinal slot in the first handle; a second longitudinal fin on an exterior surface of the locking cartridge cylinder adapted to seat within at least a portion of a longitudinal groove in the first handle, the first handle groove being offset from the first longitudinal slot in the first handle. 4. The locking mechanism of claim 1, further comprising: a) a hub core assembly operably connected to the first handle at a first side of the hub core assembly; andb) a latch assembly at least partially contained within, and operably connected to, the hub core assembly, the latch assembly including a latch adapted for translational movement roughly perpendicular to a first longitudinal axis drawn from a center point of an axis of rotation of the first handle to and through a center point of the hub core assembly, the latch moveable into and out of an opening in an adjacent jamb upon rotational movement of the first handle in the unlocked position, the latch unmoveable from out of the adjacent jamb opening in the locked position. 5. The locking mechanism of claim 4, further comprising a second handle operably connected to a second, opposing, side of the hub core assembly. 6. The locking mechanism of claim 5, wherein the hub core assembly is mountable within a door, the first handle is exposed on an exterior side of the door and the second handle is exposed on an opposing interior side of the door. 7. The locking mechanism of claim 4, wherein the hub core assembly includes a second housing connected to an opposing first housing, a) the second housing includes:a protruding first portion having a notch; anda protruding second portion; andb) the first housing includes:a protruding first portion having a notch; anda protruding second portion; wherein the second housing protruding second portion seats within the first housing notch and the first housing protruding second portion seats within the second housing notch. 8. The locking mechanism of claim 4, wherein the hub core assembly includes a second housing connected to an opposing first housing, a) the second housing includes:a substantially protruding first arcuate portion having a notch; anda protruding second arcuate portion; andb) the first housing includes:a substantially protruding first arcuate portion having a notch; anda protruding second arcuate portion; wherein the second housing protruding second arcuate portion seats within the first housing notch and the first housing protruding second arcuate portion seats within the second housing notch. 9. The locking mechanism of claim 1, further comprising a second longitudinal slot in the first handle; a first positive stop outside of a spindle and operably connected to the first handle to limit the rotation of the first handle; the first positive stop having a ring shape with: a central opening;opposing interior tabs projecting partially into the central opening; andopposing exterior tabs projecting outwardly, away from the central opening. 10. The locking mechanism of claim 1, wherein the locking mechanism is adapted to resist a torque force applied to at least the first handle of at least about 1000 pound torque when in the locked position whereby the first handle does not rotate substantially relative to the first rose. 11. The locking mechanism of claim 1, wherein in the locked position, any torque force applied to the first handle is not substantially applied to the locking tab. 12. A hub core assembly for use in a locking mechanism between a first handle assembly and a second handle assembly, the hub core assembly comprising: a first housing connected to an opposing second housing; a) the first housing including:a protruding first portion having a notch with a first through hole; anda protruding second portion;b) the second housing including:a protruding first portion having a notch with a second through hole; anda protruding second portion; and the first housing protruding second portion seats within the second housing notch and the second housing protruding second portion seats within the first housing notch. 13. The hub core assembly of claim 12, wherein the first housing has a first central opening and the second housing has a second central opening; and further including a first handle operably connected to the first housing and adapted for rotational movement. 14. In a locking mechanism having an unlocked position and a locked position, first and second handles each adapted for rotational movement; a hub core assembly operably connected to the first and second handles, a first rose adjacent the first handle and connected to one end of the hub core assembly, the hub core assembly operably connected to a latch assembly having a latch seatable, and removable, from an adjacent jamb opening in the unlocked position and not removable from the adjacent jamb opening in the locked position; the improvement comprising locking means for (a) preventing removal of the latch from an adjacent jamb opening in the locked position, and(b) permitting removal of the latch from an adjacent jamb opening in the unlocked position, the locking means including (i) a locking cartridge at least partially contained within at least the first handle or the first rose, and(ii) a locking tab (I) seatable within the first rose for maintaining the seated latch within the adjacent jamb opening in the locked position, (II) operably connected to the locking cartridge and adapted for movement from a first position in the unlocked position to a second position in the locked position, and (III) biased in the unlocked position by a lock pin spring proximate a lock pin by which the locking tab is operably connected to the locking cartridge. 15. The locking mechanism of claim 14, wherein: a) the first handle includes a first longitudinal slot and a longitudinal groove parallel to, and offset from, the first longitudinal slot;b) the first rose includes a second longitudinal slot aligned with the first longitudinal slot;c) the locking cartridge includes a longitudinal fin on an exterior surface of the locking cartridge adapted to seat within at least a portion of the longitudinal groove in the first handle; and the locking tab adapted for movement at least partially into at least the second longitudinal slot in the first rose in the locked position; and completely out of the second longitudinal slot in the first rose in the unlocked position.
