Container cover/door with high security locking system comprises a metal cover/door having a first through opening surrounded by a first metal sleeve or collar extending inwardly from the outer surface of the cover/door. Fixedly attached to the inner surface of the cover/door is a metal bracket having a second through opening surrounded by a second metal sleeve or collar that extends outwardly within the first collar. The locking system comprises a locking mechanism including a spring loaded latch contained within a housing mounted to an inner surface of the metal bracket, and a security pin having a pin head that is encased within the second collar with a close tolerance therebetween, and a pin shaft of a smaller diameter than the pin head that extends inwardly from the pin head through an opening in the locking mechanism.

1. A container cover/door with high security locking system, the cover/door being made of metal and having a first through opening surrounded by a first metal collar extending inwardly from an outer surface of the cover/door, a metal bracket fixedly attached to an inner surface of the cover/door, the metal bracket having a second through opening surrounded by a second metal collar extending outwardly within the first collar, and the locking system comprising a locking mechanism including a housing containing a spring loaded latch, the housing being mounted to an inner surface of the metal bracket, and a security pin comprising a pin head and a pin shaft, the pin head having a larger outer diameter than the pin shaft, wherein the pin head is received within the second collar with a close tolerance therebetween, and the pin shaft extends inwardly from the pin head through an opening in the locking mechanism, further comprising a metal barrier between the locking mechanism and the metal bracket, the metal barrier having a hole through which the pin shaft extends, wherein the hole has a smaller diameter than the outer diameter of the pin head, whereby a surface of the metal barrier surrounding the hole acts as a stop for the pin head thereby preventing any possible external abuse of the pin head from being transferred to the locking mechanism. 2. The container cover/door of claim 1, wherein studs extend inwardly from the metal bracket through aligned openings in the metal barrier and the locking mechanism housing, and nuts are threaded onto inner ends of the studs to secure the metal barrier and the locking mechanism to the metal bracket. 3. The cover/door of claim 1 further comprising means for preventing removal of the security pin from the cover/door. 4. The container cover/door of claim 3, wherein said means comprises a pin extending through a hole in an inner end of the pin shaft inwardly of the locking mechanism. 5. The container cover/door of claim 4, further comprising a washer interposed between the pin and the locking mechanism to take up any excess clearance space therebetween. 6. The container cover/door of claim 1, wherein the pin head has an outer face that contains a curvilinear groove pattern that is engageable by a designated pattern driver for rotating the security pin a part turn. 7. The container cover/door of claim 6, wherein the pin shaft has a non-cylindrical portion that matches a non-cylindrical opening in a metal body of the locking mechanism in which the non-cylindrical portion of the pin shaft is received, whereby when the security pin is rotated a part turn, the metal body is similarly rotated, causing the spring loaded latch to retract. 8. The container cover/door of claim 7, wherein the non-cylindrical portion of the pin shaft and the opening in the metal body of the locking mechanism have matching hex patterns. 9. The container cover/door of claim 1, wherein the metal bracket is welded to the inner side of the cover/door. 10. The container cover/door of claim 9, wherein the first collar is an extruded integral part of the cover/door and the second collar is an extruded integral part of the metal bracket. 11. The container cover/door of claim 1, wherein an outer end of the second collar and the security pin are flush or recessed with respect to the outer surface of the cover/door. 12. A container cover/door with locking system, the cover/door being made of metal and having an extruded first collar extending inwardly from an outer surface of the cover/door, the first collar defining a first through opening in the cover/door, a metal bracket welded to an inner surface of the cover/door, the metal bracket having a second extruded metal collar extending outwardly within the first collar, the second collar defining a second through opening in the metal bracket, and the locking system comprising a locking mechanism including a housing containing a spring loaded latch, the housing being mounted to an inner surface of the metal bracket, a security pin comprising a pin head and a pin shaft, the pin head having a larger outer diameter than the pin shaft, the pin head being flush mounted within the second collar with a close tolerance therebetween, and the pin shaft extending inwardly from the pin head through an opening in the locking mechanism, and a metal barrier between the locking mechanism and the metal bracket, the metal barrier having a hole through which the pin shaft extends, the hole having a smaller diameter than the outer diameter of the pin head, whereby a surface of the metal barrier surrounding the hole acts as a stop for the pin head. 13. The container cover/door of claim 12, wherein the pin head has an outer face that is flush with an outer end of the second metal collar, and the outer face of the pin head contains a curvilinear groove pattern that is engageable by a designated pattern driver for rotating the security pin a part turn. 14. The container cover/door of claim 13, wherein the pin shaft has a non-cylindrical portion that matches a non-cylindrical opening in a metal body of the locking mechanism in which the non-cylindrical portion of the pin shaft is received, whereby when the security pin is rotated a part turn, the metal body is similarly rotated, causing the spring-loaded latch to retract. 15. The container cover/door of claim 12, wherein studs extend inwardly from the metal bracket through aligned openings in the metal barrier and the locking mechanism housing, and nuts are threaded onto inner ends of the studs to secure the metal barrier and the locking mechanism to the metal bracket. 16. A container cover/door with high security locking system, the cover/door being made of metal and having a first through opening, a metal bracket fixedly attached to an inner surface of the cover/door, the metal bracket having a second through opening and the locking system comprising a locking mechanism including a housing containing a spring loaded latch, the housing being mounted to an inner surface of the metal bracket, and a security pin comprising a pin head and a pin shaft, the pin head having a larger outer diameter than the pin shaft, wherein the pin head is received within the second opening with a close tolerance therebetween, and the pin shaft extends inwardly from the pin head through an opening in the locking mechanism, further comprising a metal barrier between the locking mechanism and the metal bracket, the metal barrier having a hole through which the pin shaft extends, wherein the hole has a smaller diameter than the outer diameter of the pin head, whereby a surface of the metal barrier surrounding the hole acts as a stop for the pin head thereby preventing any possible external abuse of the pin head from being transferred to the locking mechanism. 17. The container cover/door of claim 16, wherein the pin head has an outer face that contains a curvilinear groove pattern that is engageable by a designated pattern driver for rotating the security pin a part turn, and the pin shaft has a non-cylindrical portion that matches a non-cylindrical opening in a metal body of the locking mechanism in which the non-cylindrical outer portion of the pin shaft is received, whereby when the security pin is rotated a part turn, the metal body is similarly rotated. 18. The container cover/door of claim 17, wherein the non-cylindrical portion of the pin shaft and the opening in the metal body of the locking mechanism have matching hex patterns.
