I beleive the tumblers are all screwed up in the cyl. my daughter was able to get the key out, but I haven't messed with it. It sounds like if I can get the old lock cyl out the best thing to do would be take it to a lock smith and have him replace the worn tumblers or purchase a replacement lock cyl and install that then she would have (2) keys one for Ignition and one for door locks.
