Hmm... yes I turn the wheel back and forth a little, it wasn't locked. I kind of tried everything I could think of, figuring that I had forgot something really obvious, but nothing worked, until I pretty much got ou,t and then got back in, put the key in, and it worked.
I am having the same problem with my IS300 the key won't turn I have tried everything ummmmm 2 days now hate to have it towed if it is something minor
