Key won't turn in my 2006 Holden Crewman?

You might find that the ignition barrel has collapsed internally, jamming the whole thing up and refusing to start the car. But before you call in the locksmith, try this: The ignition barrel on this car also operates the steering lock mechanism. If the key has been removed and the steering locked at a particular angle, you can have these very symptoms next time you try to start the car.

What’s happening is that the steering lock is resting against the little mechanism that frees it when you turn the key, making the key feel like it’s jammed. The solution is to pull the steering wheel one way or the other until you feel it move a millimetre or two. At that point, you might find the key will now turn freely.
