Hello,
Found this at ClubGP...Not promoting the site, just giving credit, where credit is due.
"Not sure of the cause, but yeah, there's a release under the steering column, almost right below the keys, there's a round plastic cover, pop that off, and stick a thin screwdriver or something similar up there til you feel it push the release button. Then you can remove your keys at least til you figure out what's wrong."
There is more there, didn't find the real problem. Maybe someone else will come up w/ it, until then, atleast you can get the key out.
Later now,
