This is what has happened to me several times..

- I move the key position from "running" to "accessory". I then attempt to start the car. The key will not move. I must rotate the key fully to it's "remove" position (counter clockwise) first before it will rotate clockwise to start the car.

When I went to pick up the car this happened also. The Sales Rep was no help, much to his embarrassment . He called out a tech who turned the key counter clockwise then clockwise.

Probably not your problem but it's worth mentioning.
