This sounds very familiar to the "theftlock" system found on select GM vehicle's radios such as the "moonsoon system." I am not familiar with the Chrysler way they do it.....BUT, if you have not CHANGED the code since owning the car, then the generic code that the manufacturer programed into it should be printed in the owner's manual and certainly if not, the dealer should be able to assist. If this radio is aftermarket, we're pissing up a rope here entirely.
If all else fails, there may be an INTERNAL fuse INSIDE the radio that will have to be pulled in order to get it to reset itself. This one's really on you because other than what's been stated, none of us can really help you. Good luck!
