This is a general overview and may not cover all variations or specific nuances of your particular vehicle. Proceed at your own risk.
Tools You'll Likely Need:
* Security Torx bits: These are crucial for many GM vehicles of this era. The size will depend on your specific model, check your repair manual.
* Screwdrivers (Phillips and possibly flathead): For various screws and trim pieces.
* Pliers: For potentially stubborn connectors.
* Ignition switch removal tool: This special tool can make the process easier and safer. You can often find them at auto parts stores. It prevents damage to the ignition cylinder.
* New ignition cylinder: Make sure you get one that matches your car's key.
* Socket set: Potentially for removing steering wheel related parts.
* Wrench set: Potentially for removing steering column related parts.
* Penetrating oil (like PB Blaster): To help loosen any seized screws or bolts.
* Shop rags: To keep things clean and prevent scratches.
General Steps (Consult your repair manual for precise instructions):
1. Disconnect the battery: This is crucial for safety. Disconnect the negative (-) terminal first.
2. Steering Wheel Removal (May or May Not Be Necessary): Some procedures may require removing the steering wheel to access the ignition cylinder. This is a more advanced step, and requires specialized tools and knowledge to avoid damaging the airbag (if equipped). Your repair manual will tell you if this is necessary.
3. Remove the Steering Column Shroud: This is the plastic cover around the steering column. It's usually held on by screws.
4. Access the Ignition Cylinder: Once the shroud is removed, you should be able to see the ignition cylinder. There will likely be screws holding a retaining ring or plate in place around the cylinder.
5. Remove the Retaining Ring/Plate: Carefully remove these screws and the retaining mechanism.
6. Remove the Ignition Cylinder: This is where the ignition switch removal tool comes in handy. It helps to safely remove the cylinder without damaging it. If you don't have one, proceed with extreme caution. There's often a slot or pin that needs to be engaged to release the cylinder. Your repair manual will show you.
7. Install the New Ignition Cylinder: This is the reverse of the removal process. Ensure it's properly seated and the retaining ring/plate is securely fastened.
8. Reassemble Everything: Put the steering column shroud back on, reinstall the steering wheel (if removed), and reconnect the battery.
9. Test the New Ignition Cylinder: Try your key to make sure everything works correctly.
Important Considerations:
* Key Matching: You'll need a new ignition cylinder that matches your car's key or have a new key made to match the new ignition cylinder. Your local locksmith or auto parts store can assist.
* Security Features: Some ignition cylinders have anti-theft features. Replacing it might require additional steps to reprogram or disable these features.
* Airbag Safety: If you need to remove the steering wheel, disconnect the battery and take extreme precautions to avoid accidentally deploying the airbag.
