Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the ignition switch bolts.
Tighten

Tighten the bolts to 10 N?m (89 lb in).

Install the trim plate bezel to the I/P cluster. Refer to Trim Plate Bezel Replacement - Instrument Panel (I/P) Cluster .

There is an Ignition switch that is located under the dash. On the other hand if your referring to where the ignition key goes in then this part is called an ignition cylinder. If it is the ignition cylinder (or tumbler) then yes the steering wheel must be removed to replace this and you will need special tools to do it. I would not suggest doing this yourself with no experience as there are lots of small pieces and parts in there. The ingition switch is located under the dash on the steering column and has a wire harness attached to it with numerouse wires. This is replaced by removing 2 small bolts and unplugging it. There is a rod running down the column that goes into a slot on the back side of the ignition switch. It must be placed in the hole where the old old was and then the switch may need adjusting forward or back to properly work.
Hope this helps.
