Here's a breakdown of your options:
* Dealership (Pontiac, if one's still around, or a GM dealership): They are the most expensive option but can potentially get the exact original key, especially if it includes the electronic components. The availability of original parts for a car that old is uncertain though.
* Locksmith: This is probably your best bet. A reputable locksmith specializing in automotive keys can often make a key from the lock cylinder or even cut a key based on the vehicle's VIN (Vehicle Identification Number) if they have access to the appropriate databases. They can also handle keys with electronic transponders (the chip inside the key). Expect this to be more expensive than the DIY options below but more reliable than cutting a key yourself.
* Auto Parts Store (e.g., AutoZone, Advance Auto Parts, NAPA): These stores *may* be able to provide a blank key that you could have cut by a locksmith (they usually don't do key cutting themselves), but finding the correct blank for such an older car might be challenging.
* Online Retailers (e.g., Amazon, eBay): You might find blank keys or pre-cut keys on these platforms, but verify their compatibility with your car model carefully. Again, you'll likely need a locksmith to cut a key from a blank unless you're very skilled. Be wary of counterfeit keys.
Important Considerations:
* VIN number: Have your VIN ready when contacting any of these places. It's essential for confirming the correct key type.
* Key type: Do you need a simple mechanical key, or one with an electronic transponder for immobilizer systems (which prevents the car from starting without the correct key)? The locksmith will be able to tell you if it's an electronic key based on your lock cylinder.
* Cost: Expect to pay significantly more for a key with an electronic transponder than a simple mechanical key.
In summary, a locksmith is likely your best option for a balance of price and convenience. They can handle both simple and electronic keys. Start with them, but be prepared for a bit of searching if it's an electronic key and original parts are hard to locate.
