Places will charge between 1-1.5 hours to replace the ignition switch. depends on the labor rates in your area. A dealer will be around $100. an hour and a repair shop will be between $50-$85.
A new ignition switch will cost around $200 at a dealer and about 50- $75. cheaper at a discount auto part store.
These are for the electrical part. If you need the ignition lock cylinder also, It will be more. The Ignition lock cylinder is the part that the key goes in and goes inside the ignition switch.
These are not hard to do.
I can put some instructions together and you can see if you want to do it your self.
There is not much out there as far as video repair instructions.
Yes, this is what happens when it goes out. common issue.
