Re: "if the manufacturer does cheat, and use a single password/key"
Off topic a bit but I bought 2 cases for my rifles from the same manufacturer. They are different sizes. The other day I found out that all 4 keys (2 came with each case) will open both cases. Not really a big deal as the locks are to keep the grandsons out of them. They have padlock holes so in case I have to travel with them I will use padlocks.
