The metal case was open and broken, no steam key anywhere, and the pip boy doesn't even seem to latch when you try to put it on how do youi keep it from opening back up when you move it?

This sounds loike bad news bud. I recommend watching an unboxing on youtube and taking notes on what is wrong/missing from yours. THEN call who you bought it from and have a friendly chat with a member of management.

I know its like oh ill just get a new one..........
