Car doesn't start after I used an old key.
Lost keys for my Chrysler300 so had a new one made. Worked fine until I
found lost keys and tried one. Now car won't start. Unhooked battery but
didn't reset. Any ideas?
Clearly it is a security system issue. You will probably have to take the car to a Chrysler dealer.
