i believe that the ignition is rivitted on the colum.

there is a little lever if you take the plastic off around it. where the key go's.
when you do that look at the key and right behind it is the little lever its got a red tip.
make sure thats not stuck in the middle or it will happen sometimes. My key got stuck in the ignition alot and that was the problem mabye same issue. just my 0.02.
