* Dealership: This is often the most expensive but also the most reliable option. They can program a new key to match your vehicle's computer system. Be prepared to show proof of ownership.
* Locksmith: A reputable locksmith specializing in automotive keys is a good alternative. They may be able to create a new key either by decoding the lock cylinder (this is more difficult and may not always be possible on newer vehicles) or by programming a new key if they have the appropriate equipment. Prices will vary significantly depending on the locksmith and the method used. Get quotes from several locksmiths before committing. Look for locksmiths who advertise experience with Ford Windstars or older vehicles.
* Online Key Services: Several companies offer key replacement services. They'll often require you to provide information about your vehicle (VIN number) and may need to ship you a key blank to be cut and programmed. Research carefully to ensure the company is reputable and check reviews before ordering. Be wary of scams.
* Aftermarket Key Programmers: These are devices that can be used to program keys, but they are typically only used by professionals. If you have some technical skill and are comfortable working with electronics, you could potentially purchase one but the learning curve is significant and risks damaging your car's computer system if used incorrectly. This is *not* recommended for someone without significant automotive experience.
Important Considerations:
* VIN Number: You'll need your Vehicle Identification Number (VIN) for any of these methods. It's located on your vehicle's dashboard, usually visible through the windshield.
* Proof of Ownership: Be prepared to provide proof of ownership (title or registration) when getting a replacement key, especially from a dealership or reputable locksmith.
* Cost: Expect to pay significantly more than a simple key replacement for a standard car. The programming aspect adds to the expense.
* PATS System: Your 2001 Windstar likely uses a Passive Anti-Theft System (PATS). This means the key isn't just about starting the car; it has a transponder chip that communicates with the vehicle's computer. A simple key copy won't work; you need a programmed key.
In summary, a locksmith is likely your best bet for a balance of cost and convenience compared to a dealership, but always get multiple quotes and check reviews before making a decision. Avoid untested online services to minimize the risk of fraud.
