* Dealership: A Buick dealership will be able to program a new key fob for your car, but it will likely be the most expensive option. They'll need your vehicle identification number (VIN).
* Locksmith: A locksmith specializing in automotive keys can often create a new key, including the transponder chip needed for the car's immobilizer system. This is often a less expensive option than the dealership. Make sure to choose a reputable locksmith.
* Online Retailers: Websites like Amazon or eBay sell key fobs and blanks. However, you'll likely need to have the key cut and programmed separately, either by a locksmith or a dealership, as the online retailers generally don't program them. Be cautious when buying online and ensure the seller has good reviews. You'll need to know the correct key type for your LeSabre before purchasing.
* Auto Parts Stores: Some auto parts stores may be able to duplicate your key, but this largely depends on the specific store and the complexity of your key.
Before you go anywhere, it's helpful to:
* Check your existing keys: You might have a spare key somewhere hidden that you've forgotten about.
* Determine the key type: Check your current key to see if it's a simple key or a key fob with remote controls (lock/unlock, alarm). This will help you when ordering or requesting a replacement.
The best option often depends on cost and convenience, but remember that for a 2000 LeSabre, getting the key programmed correctly is crucial to starting the vehicle due to the immobilizer system. Locksmiths and dealerships are the most reliable for programming.
