I need help 98 expedition lost key now need key codes for remake new key any codes or anything cheap besides 120 and up

Did you try to get an estimate from a local locksmith to come and make a key for your vehicle?

Other option would be to call a dealership, provide your vehicle ID NO and registration and maybe they might be able to come up with a code/key, although due to the year kinda iffy.
If and when you get a key consider having 2 made. With 2 working keys you can program up to 8 yourself.

Your vehicle may have a security system where the new key(s) have to be programmed to your vehicle.
Locksmith has to be registered and certified to code new key for your vehicle , otherwise you vehicle may not even start. This can now get pretty expensive.
