1. Dealership or Locksmith:
* Dealership: This is generally the most expensive option, but also often the most reliable. They can program a new key that will work perfectly with your vehicle's immobilizer system. You'll likely need to prove ownership (title or registration).
* Locksmith: A reputable locksmith specializing in automotive keys can often create a new key for less than a dealership. They may be able to make a key from the vehicle's lock cylinder or by decoding the vehicle's computer system, depending on the year and model. Make sure to check reviews and ensure they're experienced with older vehicles.
2. Alternative Key Solutions (If Applicable):
* Spare Key Hidden Somewhere: The most obvious, yet sometimes overlooked, solution. Check thoroughly for any hidden spares.
* Spare Key with Another Person: Did you give a spare to a family member or trusted friend?
3. Important Considerations:
* Immobilizer System: 1998 Tahoes almost certainly have an immobilizer system, meaning a regular key blank won't start the car. The new key needs to be programmed.
* VIN Number: You'll need your Vehicle Identification Number (VIN) for any of these options. This is crucial for ordering parts and proving ownership.
* Cost: Prices vary significantly depending on your location, the locksmith/dealership, and whether they need to decode the car's system or use the lock cylinder. Get multiple quotes.
* Time: Depending on the method, getting a new key can take anywhere from a few hours to a few days.
In summary: Contacting a reputable locksmith is usually the most cost-effective solution, while a dealership offers guaranteed compatibility. Before you call anyone, double-check for hidden spares and consider if someone else might have a key.
