Go to your dealer or local indy mechanic and buy a new key and tumbler set. With some luck, the new key will permit you to get the tumbler set in there to turn once more, and you can remove the tumbler.

Otherwise, it's about 4 hrs labor to get the old one out.

As I've said many time before (although no one reads it until the key won't turn....) -- get the tumbler changed the first time it acts up, DON'T wait until you cannot use the key! When the key works, tumbler change is a 5 minute job. When it bad, big PITA.
