Okay, so out of curiosity, I tried the same thing with a normal wooden chest, I locked it down, set security to anyone, dropped a normal smithy hammer in the chest, logged onto another toon, and that toon could open the chest, but couldnt take the hammer out? Im curious if you are even supposed to be able to set security on a "locked down container" cuse it makes no sense, if i set it to anyone, anyone should be able to remove an item from the chest.
Not even a character from the same account as the character who locked it down, cannot remove it.. even using "I wish to release this" it just says, "You may not release this while its is in a container" just a thought.
