I have 98 chrysler sebring and my ignition is lock and i cant turn my car on

First if the steering wheel is locked try to turn the steering wheel away from the locked position and and jiggle the key at the same time. If you have another set of keys try them too. I did have one of these tumblers go bad before if the other two things don't work you will probably have to replace the tumbler which is kinda hard to do if you can't turn the key on because to get the tumbler out you have to have the key on and push a button underneath as part of a security so its not easy to steal. You can get it out with a hammer and punch where the button is to force it out but be carefull not to break it. If you dont have a new tumbler right away you can use a large screwdriver to start it temperoly after you get the old tumbler out.
