This one is probably going to have to go to a shop for diagnosis. It could possibly be a hub, steering gear, strut or even a tire. It could be a CV joint or a broken motor mount. Without actually driving your car this is pretty hard to guess at. Sorry I couldn't be of more help.

The rattling you are asking about turned out on my 320 to be the catalytic converter breaking up internally.
Is your oil level?

Possibly a loose heat shield or other component.
I am not sure what causes this, but I have had times when my ignition key would not turn. The solution to the main problem is to turn the steering wheel slightly. This usually allows the ignition key to turn.
