Last night while in town my ignition lock seized, solid in the run position. '81 Cordoba with tilt and floor shift auto. Key wouldn't wiggle, lock wouldn't budge. I moved, slammed and jammed the floor shift lever which is independent of the key and column, tilted the wheel up and down, tapped and slammed the column attempting to jar something free. So where do I start? The column intimidates me. Anyone have some advise or experience they care to share on this?
