Option 1: Check the Owner's Manual
- Refer to the owner's manual or maintenance guide that came with your vehicle. The key code may be listed in a designated section, often under "Vehicle Identification Numbers" or "Key Codes."
Option 2: Contact Your Local Ford Dealership
- Visit your local authorized Ford dealership. Provide them with your vehicle identification number (VIN) and proof of ownership (such as your vehicle registration). They should be able to provide you with the correct key code.
Option 3: Contact a Locksmith
- If you are unable to obtain the key code from the owner's manual or dealership, you can contact a reputable locksmith. They may have the necessary equipment and resources to retrieve or decode the key code for your Grand Marquis.
Please note that unauthorized key duplication may be illegal in your area, so always prioritize obtaining the key code from legitimate sources.
