The actual ignition cylinder is held in by a screw on the interior of the steering wheel column that fits into a detent on the ignition cylinder housing. You do not need to remove any steering column panels, but you will need to remove the steering wheel and various components (turn signal/combination switch, etc) underneath to get to the screw. You will need a steering wheel puller. If you don't have one, get a Chilton's manual at a minimum. It depicts many of the procedures/parts fairly well. Be very mindful of the way parts fit in there as you remove them. If possible, use a digital camera to take pictures as you remove the various components to aid in reassembly should you forget how things fit together. Its not a difficult procedure, but there are a few pieces that you have to remove to get to the screw holding the cylinder in.
