Some 2014-2015 facelifts shipped with mid-cycle chip swap — confirm transponder ID from a working key with FORScan or Lonsdor K518 reader before quoting.
- Tool kit context: Autel IMKPA Ford module is the dominant add-key accessory (~$5-15/session for ID49 cloud calc). AD Smart Pro ADS178 also strong on Ford.
