Can you get a new key for your Navigator 1999 if you lost all?

Yes, you can get a new key for your 1999 Navigator even if you've lost all original keys. You will need to provide the Vehicle Identification Number (VIN) and proof of ownership to a Ford dealership or a qualified locksmith. They can create a new key for you, but if your vehicle has a transponder key, they may need to program it to work with your vehicle's ignition system. It's advisable to contact your local dealership for specific requirements and costs.
