Query: The keys are all identical across all units

I bought one for each of my sons, thinking they would each have their own private key. Unfortunately, the keys are identical, just a flap of metal to turn the release mechanism. That would be OK if buying only one, but I wanted each to be different, so they're going back. I may buy adult lock boxes with padlocks. Oh, and I have to say, "Must accept any color" == LAME.Update: For about the same price, I bought 2 SentrySafe CB12's. SentrySafe can make real cash boxes, with real keys, much larger (increased material cost), and sell for about the same price. A way better deal, and the kids love their "grown-up" cash boxes. LOL Seriously, don't you long for the day when you could get excited over something that small?SentrySafe CB12 Large Cash Box, BlackThe big ones also have room for books, small toys, etc.
