It is a diy'er job and pretty straight forward BUT you have got to get it to turn to be able to get it out. I would keep trying to work the steering wheel and key at the same time. Once you get it to the correct position then get a straightened paper clip that will fit into the little hole close to where the key goes. You have to "release" the catch using the paper clip and then unscrew the black ring around the tumbler. As you unscrew it you can ease the tumbler out.
