If you're missing the key, you'll need to get a replacement key. Your options include:
* Dealer: A GM dealership is the most reliable source. They can likely create a key based on your vehicle's VIN. This is generally the most expensive option.
* Locksmith: A qualified automotive locksmith may be able to create a key, often at a lower cost than the dealer. They might even be able to manipulate the mechanism without a key, but this is risky and could cause further damage.
* Online services: Several online services offer key duplication or replacement. Be wary and only use reputable services.
Do not attempt to force the mechanism. You could seriously damage the steering column, potentially rendering it unusable and creating a serious safety hazard. Repairing the damage from forced entry will be significantly more expensive than obtaining a replacement key.
Once you have the correct key, you can then follow appropriate repair guides specific to your vehicle's year and model. These guides may be found online through repair manuals (like Chilton or Haynes) or YouTube videos. However, if you're not comfortable working on your car yourself, taking it to a mechanic is always the safest option.
