If your key is awkward to turn in the ignition barrel, don’t ignore it. It won’t go away. Squirting WD40 in there won’t magically regrow a worn key, a collapsed spring or other broken part.
One day you’ll try to turn it, and you can’t. You’re stuck. We were able to root-canal the failed internals of the above Ford lock out, disable the steering lock and get the customer driving again. It would’ve been much cheaper and easer to have had it replaced before it jammed.
This is especially common on Transits and other builders/work vans but does happen to cars too. VW/Audi cars are particularly prone.
