Hello Fatherofnine,
Welcome to Microsoft Community.
I have fully read everything you have posted here. If your description is correct, the keyboard is not available when you separate the screen from the keyboard.
The Surface Book 3's screen and keyboard are physically connected through ports, and the keyboard doesn't support wireless connectivity, so it can't be used with a separate screen like the Surface Pro Flex keyboard.
So in fact your Surface Book 3 is working fine.
