Replace ignition key tumbler - 1992 Buick LeSabre

The first thing you have to do before you start is take your old key and get a new key made with the right resistor pellet as your old key. They have to cut the new key to the dummy key so it will turn the lock cylinder. The car won't crank with the dummy key cause there is no pellet in it.

Your going to need a steering wheel puller and a lock ring depressor tool. Disable the driver's air bag from the yellow connector under the dash. Remove the airbag and unplug its connector. Disconnect by rotating counter-clock wise the horn connector. Put the airbag facing up on the back seat. Remove the steering wheel nut and use the steering wheel or harmonic balancer puller to remove the steering wheel.
Note: there is a mark on the shaft that lines up on the steering wheel's mark.

Remove the clock spring c clip. Pull the clock spring out enough to let it dangle. Do not rotate the clock spring or it will break later after you reinstall it. Remove the wave washer and depress the lock ring cam with the lock ring depressor tool. Remove the metal ring with picks and small screwdrivers. Remove the tool and lock ring. Unscrew the hazard switch button with phillips screwdriver. Then remove the turn signal
level cam screws from turn signal switch. Remove the three turn signal switch screws.

Go under the dash and unbolt the large connector halves. Just follow the wires that run through and under the column to find the connector. There is a plastic piece that the wires in the column come out of. Squeeze the plastic pieces tabs together and pull the plastic wiring protector out. Undo the small connector that has the two little white wires on it. Pull the turn signal switch out far enough to let it dangle. Using a pair of needle noise gently remove the key chime switch. Pull it out gentle like you are picking a nose hair. You'll see a bolt with an torx head. Remove the bolt and pull the orange white wire retainer from its hole. The ignition switch should slide out.

Tie a piece of string to the end of the white wire connector you unplugged. Then pull the white wires up through the column along with the string. Cut the string from the connector after you fish it out. Tie the end of the string to the new ignition switch white wire connector and gently pull on the other end of the string at the bottom of the dash to fish the wires down into the column. From there everything is reversed
