Does a 2003 Ford ignition key have chip?

No, not all 2003 Ford vehicles had ignition keys with chips. Whether or not a 2003 Ford uses a transponder key (key with a chip) depends on the specific model and trim level. Some models were equipped with passive anti-theft systems requiring a chipped key, while others were not. You would need to check your owner's manual or the vehicle's documentation to determine if your specific 2003 Ford uses a chipped key.
