A ford dealer or locksmith are the only places to get the key code. Some locksmiths do not have this. It is not anywhere on or in the vehicle. A key code is stored by ford with the vin#
I have been at the ford dealer for 4+ years and have never seen or read or heard of the key code being in or on the car anywhere. I am a ford employee and I don't even have access to get these codes only parts or service managers have this access on the ford website.
