Re: changing an ignition cylinder on a 1995 buick century
There is a special spring compressor used to compress the lock plate spring underneath it, then you will be able to remove the snap ring holding the lock plate down, and lock plate spring. You will then need to remove the blinker multi function switch. You will then have access to the bolt holding in the ignition cylinder. There are 2 wires attached to it that run down the inside of the steering column that will need to be unplugged at the base, and new wires threaded down through the steering column when installing the new ignition lock cylinder.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

YOU JUST NEED TO REMOVE THE STEERING WHEEL.
You have to remove the Airbag, so take the negative lead off the truck battery. Remove the airbag. remove the steering wheel. You will need a steering wheel puller or some good luck in getting it off without one. Under the steering wheel you will have a retaining plate. It has a spring clip around the center shaft that has to be removed. not real easy. it has a big spring behind the plate you'll have to contend with. Once you get the clip off, remove the plate.You'll have to remove the screws holding the turn signal stalk in place. Remove the screw holding the ignition cylinder in place. The whole thing should slide out now.
Pull airbag you are going to need a wheel puller a pair snap ring pliers and a lock plate compreser all loaner tool avalable at most parts stores. pull wheel them yellow airbag control moduel then comes the lock plate remove it there is small ring locking it onto stearing shaft once you pull that you will be able to see ignition cylinder small star bit screw above it remove it and pull out cylinder. put back together in reverce order
need to have the tool to compress the steering wheel lock plate and steering wheel and then it is not bad to do.
you can get them on rental from auto zone!
first remove steering wheel with puller then remove lock plate with
compressor tool and you will have to take the clip out after
compressing the lock plate you will see the c-clip around the column
once that is off you can remove lock plate and gain
access to the multi function assambly that un screws with three main
philliups head screws and the screw hoding the blinker arm and the
flasher switch to it.
once those all are remove you can pull
straight back towards you on the multi fuctin ***. it has a bunch of
wire connected to it but don't worry they will pull out just far enough
to get that out of your way.
once pulled back you will see a
plastic piece that has two brass metal tabs on it on the right inner
side of the column near the ignition switch. carefull pull straight
back on it being extra crefull not to break it and once that is out you
will need a t20 torx screw driver to remove the retaining torx bolt
holding the ignition in.
once that is out your ingintion will come right out. install everything in the reverse procedure.
let me know if you have any more question. good luck
You may have a problem with the lock cylinder istelf, they have a tendancy to become "unstaked" which causes them to jam-- sometimes they won't turn off, others won't turn enough to start.
The other problem may be the ignition switch, which is located down the steering column, under dash. The switch is governed by the rotation of the lock cylinder (key) moving a rod by way of a pinion and rack.
The switch my be adjusted or replaced without removal of the seering wheel or lock assembly.
Expect to pay $250 to $400 depending on the actual failure.

The ignition switch or the ignition tumbler? They are two different
things. The tumbler is where you put the key, and the ignition switch
is bolted to the bottom of the steering column.
If you are talking about replacing the ignition switch and your truck
is equipped with an airbag (in 1995 Chevy trucks had them as standard
equipment) you should probably go to an expert for this question. I
would take the time to visit the local dealership and just find a
mechanic and speak with him for a few minutes, chances are he'd help
Usually with airbag situations you are suppose to unplug the battery
from the system and then wait xx minutes (I've heard from 15 to 60
minutes) in order to wait for the airbag electronic system to lose
power, causing potential accidental deployment.
