I previously posted I had my ignition switch replaced. It was just worn out after 9 years and at times it was difficult to get it to turn on. Then it hit me last night after I got in bed - What about the key fitting the driver's door lock? I have the fob and it opens the door fine, but nothing was ever said about changing the door lock. So when I got up a few minutes ago I went out and tried the new key in the driver's door and it opened fine.
How does this work? New ignition key and it works on the old lock in the door or did they change that lock too and I just didn't know it? I don't see a door lock on the parts list.
Help from those smarter than me.
