My 2002 XG350 would occationally have the ignition key turning so hard I
thought I might break the key off. Next time everything would work fine.
Finally figured out that it has something to do with the steering wheel lock
and if you giggle the steering wheel back and forth a little when the key is
hard to turn it frees things up and the key turns easily. Don't know if
anyone else has seen this, but I thought I'd post it in case anyone else is
having troubles.
