A tubular radial pin tumbler lock is described. The radial pin tumbler lock has an outer shell, an inner shell housed in the outer shell, and a spindle housed in the inner shell. The spindle has a spindle head with an uneven number of irregular sides. A plurality of radial locking pins are arranged radially from the spindle. A crown on the spindle encases the locking pins. An anti-drill feature is included on the spindle head. An annular space between the inner shell and the spindle head allows access to the radial locking pins for operating the radial pin tumbler lock.

What is claimed is: 1. A radial pin tumbler lock comprising: an outer shell; an inner shell housed in said outer shell; a spindle housed in said inner shell, said spindle comprised of a spindle head, a spindle crown and a portion extending from said spindle crown for engaging a lock bolt, said spindle head comprising an uneven number of irregular sides, said spindle crown comprising an uneven number of pin enclosures comprising an axial depth, where a plurality of positions of said uneven number of irregular sides relative to said spindle crown defines a plurality of keyways; an uneven number of radial locking pins comprising combination pins of a plurality of different axial lengths and bottom pins, said radial locking pins arranged radially from said spindle head in said pin enclosures where said inner shell substantially constrains said radial locking pins from moving in a direction radially to an axis of rotation of said spindle; and an annular space between said inner shell, said spindle head and an inner surface of said spindle crown, said annular space having dimensions allowing access to said radial locking pins where each of said radial locking pins is required to be depressed within said pin enclosures a distance substantially equal to said axial depth minus said axial length of said respective radial locking pin for operating the radial pin tumbler lock. 2. The radial pin tumbler lock as recited in claim 1, wherein said radial locking pins are constrained from moving in a direction radially outward from said spindle. 3. The radial pin tumbler lock as recited in claim 1, wherein one of said dimensions of said annular space defines a smooth cylindrical surface. 4. The radial pin tumbler lock as recited in claim 1, wherein said spindle head further comprising an anti-drill feature located axially of said spindle. 5. The radial pin tumbler lock as recited in claim 4, wherein said anti-drill feature is a ball. 6. The radial pin tumbler lock as recited in claim 4, wherein said anti-drill feature is a dimple. 7. The radial pin tumbler lock as recited in claim 1, wherein one of said irregular sides is shorter than the other sides. 8. A radial pin tumbler locking apparatus comprising: an outer shell; an inner shell housed in said outer shell; a spindle housed in said inner shell, said spindle comprised of a spindle head, a spindle crown and a portion extending from said spindle crown for engaging a lock bolt, said spindle head comprising an uneven number of irregular sides, said spindle crown comprising an uneven number of pin enclosures comprising an axial depth, where a plurality of positions of said uneven number of irregular sides relative to said spindle crown defines a plurality of keyways; an uneven number of radial locking pins comprising combination pins of a plurality of different axial lengths and bottom pins, said radial locking pins arranged radially from said spindle head in said pin enclosures where said inner shell substantially constrains said radial locking pins from protruding from said crown and said crown substantially constrains said radial locking pins from moving in a direction radially to an axis of rotation of said spindle; a tubular key, said tubular key comprising a inner shape matching said spindle head, where an uneven number of irregular sides of said inner shape are positioned to match a keyway defined by said spindle head and said spindle crown, and an uneven number of axial cuts on a bottom of a tubular surface of said tubular key, said axial cuts comprising axial dimensions corresponding to said plurality of different lengths of said combination pins; and an annular space between said inner shell, said spindle head and an inner surface of said spindle crown, said annular space having dimensions allowing access to said radial locking pins by said tubular key where each of said radial locking pins is depressed within said pin enclosures a distance substantially equal to said axial depth minus said axial length of the respective combination pin for operating the radial pin tumbler locking apparatus. 9. The radial pin tumbler locking apparatus as recited in claim 8, wherein said radial locking pins are constrained from moving in a direction radially outward from said spindle. 10. The radial pin tumbler locking apparatus as recited in claim 8, wherein said spindle head further comprising an anti-drill feature located axially of said spindle. 11. The radial pin tumbler locking apparatus as recited in claim 10, wherein said anti-drill feature is a ball. 12. The radial pin tumbler locking apparatus as recited in claim 10, wherein said anti-drill feature is a dimple. 13. The radial pin tumbler locking apparatus as recited in claim 8, wherein said tubular key comprises a smooth cylindrical surface. 14. The radial pin tumbler locking apparatus as recited in claim 8, wherein one of said irregular sides is shorter than the other sides. 15. A radial pin tumbler locking apparatus comprising: a spindle comprised of: means for receiving a tubular key having an uneven number of irregular surfaces interior to said tubular key and an uneven number of axial cuts of varying lengths exterior to said tubular key and parallel to an axis of said tubular key where a plurality of positions of said receiving means defines a plurality of keyways; means for constraining radial locking pins in at least one axial direction and radially to said receiving means where said radial locking pins are arranged to engage said axial cuts of said tubular key when said tubular key is received and the radial pin tumbler locking apparatus is operated; means for engaging a lock bolt; and means for preventing drilling on an axis of said receiving means. 16. The radial pin tumbler locking apparatus as recited in claim 15, further comprising means for housing said spindle.
