Ok so I got this car for $500 and the key does not come out and I found out the tumbler need to be replaced. But also my rear driver side door, inside handle does not open the door any idea on what's wrong before I take the panel off? And my passenger mirror does not turn when I use the toggle on the drivers panel. And lastly any idea on how to remove small rust spots with out torching them out and rewelding them? Oh also there's a flutter in the brake pedal when braking is that normal for chryslers? Thank you for you time and support.
