According to the Chilton Corsica/Beretta 1988-1996 Manual, there are 21 steps to removing the ignition cylinder (and another 15 - 20 to reinstall it). Not that I don't want to past them all here, but you should get a manual... they're handy to have for any repairs.
Remove the plastic covering on the steering column. The ignition switch is the box that the ignition cylinder runs into. It's basically easy with only removing a couple of bolts to replace. The only trick is to be very careful actually pulling the box off the column. Make sure the key is in power off position. wiggle the box off, when putting the ignition cylinder into the new ignition switch you don't want to turn the key. Leave it in the off position. Then watch the rod in the rear of the new ignition switch as it goes back into the column. I have seen people have to turn the key in the ignition cylinder while pushing gently into the ignition switch. But beware it can turn into a real nightmare. If you use a bran new ignition cylinder, it will state all over do not turn the cylinder until it's installed.
