removing the ignition from 1992 3.1 lumnia

I posted on the fourms about how i lost my keys and it does not seem as anyone has a clear answer. I talked to the head instructer for auto tech. at my colldge and he told me if i could remove the ignition from my car and bring it to a dealership that they could cut me a key. Problem is i dont know the first thing about removing my cars ignition. Should I even attemt this with such little knowledge or is it a pretty easy job? If its fairly easy were can i get instructions on how to go about doing the job? By the way i got a 1992 Lumina Euro 3.1 multi port. Thanks in advance

I had the same problem with my door and trunk key so I went to a gm dealership with the vin and proof of ownership and they ordered my a key for $9.00 its that easy.
