ignation switch replacement on 1990 Dodge D150

The ignation switch in my 1990 Dodge D150 needs to be changed out, how hard is it to do? Should I get a shop to do the job? How much would it cost? Thank you

If it is only the switch and not the lock assembly, then you can probably do it your self.
Be sure to disconnect both terminals of the battery!
