I need to disarm my airbag to change my ignition lock.

I think you will find the Airbag is defective. Make sure you disarm this system before you touch anything, it can kill you.

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury

Best thing to do, honestly, is to purchase a chilton's or haynes manual when you are working around the air bags. Better safe than sorry.

REMOVAL

1. On models equipped with airbag, disarm airbag as described under MAINTENANCE PROCEDURES/AIRBAG SYSTEM DISARMING.
2. On all models, disconnect battery ground cable.

1. Install ignition switch and connect battery ground cable.

SRS wire harness is routed near the ignition switch.

CAUTION:

• All SRS electrical wiring harnesses are covered with yellow outer insulation.
• Before disconnecting the SRS wire harness, install the short connector on the airbag.
• Replace the entire affected SRS harness assembly if it has an open circuit or damaged wiring.

IGNITION SWITCH

1. Remove the steering wheel, then remove the steering column covers.
2. Disconnect the 7-P connector from the under-dash fuse box.

You will need to remove the steering wheel, if you have an airbag disarm it, this is very important, disconnect the battery and unplug the airbag diagnostic monitor, then remove the large nut retaining the wheel to the steering shaft, you will need a steering wheel puller to get the wheel off, very cheap tool avail from most parts stores, after the wheel is off remove the turn signal switch and move it to the left, under that switch you will see the pin that retains the lock cylinder, it will be a cross point screw, remove it, with the key turned to on remove the lock cylinder.

You will have to pull the steering wheel off and then the turn signal switch, under that is a release pin to remove the lock cylinder. Since you will have to remove the airbag on the wheel obtain and follow exactly the disarming instructions for the airbag system, if it goes off because it was not disarmed then very serious injury can result.
