* Dealership: This is the most expensive route, but also often the quickest and easiest. They have your car's key code and can program a new key. Be prepared to show proof of ownership.
* Locksmith: A reputable locksmith specializing in automotive keys is a good alternative. They can often create a key from scratch or program a new one, sometimes for significantly less than the dealership. They might need your VIN (Vehicle Identification Number) to get the proper key code. Make sure you choose a locksmith with good reviews.
* Used Key (Risky): Buying a used key is generally not recommended. Unless you know for certain it's the exact same key code and it's programmed correctly for your car, it won't work. Also, you'll need to have it programmed to your car's system, which might involve a visit to a locksmith or the dealer anyway.
Important Considerations:
* Year of the Cavalier: Older Cavaliers (pre-electronic immobilizers) might be easier and cheaper to have a key made. Newer models with electronic systems will require programming a new key, which adds to the cost.
* Key Type: Is it a standard key, a transponder key (with a chip), or a remote key fob? Transponder keys and fobs are more complex and expensive to replace.
* Cost: Get quotes from a few locksmiths and compare them to the dealership's price before making a decision.
In short, a locksmith is often a cost-effective middle ground between a potentially problematic used key and the higher cost of a dealer. Call around for estimates before deciding on your best course of action.
