The ignition switch is about a $10 part & very common point of failure. Buy 2 so you have one in reserve. There are lots of discussions on replacing ignition switch if you do a search. It is pretty simple, but it requires good dexterity as it is located under drivers' dash & you need to go upside down into the footwell. Pedro's garage has a writeup I think, but there are lots of threads here. Also no need for new keys or anything like that -- it is a portion of the mechanism.
