Most likely it has a cracked cam on the end of the lock cylinder. Typically it just causes a no-crank condition because it prevents the switch from turning far enough to hit the "crank" position. The dealer has a repair kit so you don't have to buy a new cylinder and have it coded to your keys, (which the dealer's parts department people can do too pretty quickly and at low cost). You get a new cam, then have to finish drilling a hole to insert a small roll pin.
Once you have the plastic trim covers off, you'll see a silver roll pin, about 3/16" in diameter pointing up toward your face. Push that in further about 1/8" to release the cylinder. I can't remember if the key has to be in or out. Once the repair is completed, push the cylinder all the way back in and turn it to "crank" with the key, like normal. That will cause the roll pin to push back out and lock the cylinder in place.
