An enclosed locking system for transportable commercial containers having swinging or roll-up access doors. A main feature of this locking system is that it renders the locked container virtually tamper-proof. Only the key access hole is externally accessible. This locking system may be added to existing containers or incorporated into new units. The system is fitted into the container horizontal frame member positioned at the lower edge of the access doors. The locking system comprises two main sub-assemblies, a cam lock housing and a removable lock assembly. The cam lock housing is bolted or welded to the container frame member, while the lock assembly is removable after a locking bolt therein is disengaged from a portion of the cam lock housing by key operation. When the lock assembly is so removed, it exposes a cam actuator lever which, when pivoted, disengages at least one cam lock from a cavity in the lower horizontal edge of the access doors, allowing entry. When this locking system is used in conjunction with a pair of swinging doors, follower bars passing through the vertical length of the doors and operably positioned to lockably engage or disengage the upper horizontal door frame member of the container in response to cam lock rotation may be incorporated into this locking system.
