not really you will need to disable the Air bag sytem(SIR) by pulling the air bag fuse and disconneting the yellow connector under each side of the dash since you have two bags and reverse procedure to re-enable. Will need a torx bit to remove two screws holding column cover on and maybe lock cylinder components on. The big connector down the steering column is actually the ignition wiring block center with two multi-switch connectors attached to either long side of center one so you will have to separate them and then the unit can be pulled out. It Can get over $200 at local store but an acdelco unit is highly recommended. It did last you this long right? Amazon has them on hand for $135.

Remember that key removed is lock position one notch forward is off, next one is on, and next one is spring loaded start. One notch backwards of lock is accy. Tranny indicator power should turn on when position is in OFF, ON, START and shut down when it LOCK or ACCY.
