Yeah,
Like I said, I have the common reg, ingot, lumber, tailor keys, but still those are great for what they are, but in all honesty they contain stack-able items which would only account for 30 - 50 items should the keys not be available.
I thought that on OSI servers and other free shards a "secure" container took 1 lock down slot, regardless of what was inside, and then items like furniture and decos were locked down, taking up most of the "lock down items" from the storage of the house.
I could be wrong.
I am also used to servers where items could remain inside a house secure as long as no one you didn't want to, entered the house. Thus the use of tables to further secure your entry of the home, and back rooms that could be additionally locked. As a fellow house looter from other shards, gaining access into peoples houses was not a difficult task, and often yield great rewards, esp. since almost anything but secure containers could be looted. Even items inside locked down containers could be removed, just not the container itself. Again, this could be ware I am getting the idea that I could possess much, much, more.
