Claim:
A security system for preventing unauthorized access to a storage container having an entryway for allowing access to a container interior, and a door for closing said entryway and preventing access to said container interior, said security system comprising: a latch assembly carried by said door on an interior side of said door, said latch assembly having a closed position for latching said door to prevent access through said entryway to said storage container, and an open position in which said door may be opened to allow access through said entryway to said storage container; an operator disposed on an exterior side of said door outside said container, said operator having an elongated shaft extending through said door for operating said latch assembly through said door; a master lock assembly carried on the interior side of said door for interlocking with said elongated shaft to prevent movement of the latch assembly between said open and closed positions; a removable master lock actuator operable from the exterior side of said storage container for operating said master lock assembly through a keyhole in said door; a tamper-resistant control carried by said door for controlling access to said master lock assembly through said keyhole; wherein said tamper-resistant control has a deployed position in which said keyhole is blocked by said tamper-resistant control to prevent said removable master lock actuator from accessing said master lock assembly through said door, and a retracted position wherein said keyhole is open and said removable master lock actuator may be inserted through said door to operate said master lock assembly; and, including a housing disposed on said exterior side of said door having a recess for receiving said operator; said keyhole for said master lock actuator passing through said housing and said door to provide access for operating said master lock assembly; and said tamper-resistant control comprising a slide-bolt, said slide bolt being mounted within said recess beneath said operator and movable between deployed and retracted positions to block and open said key hole.
