How do you know if your Ford has transponder ignition?

Depends on Model. Older Transponders: The hole in the black plastic head sometimes. If it has a transponder the hole is offset to one side and thick plastic. Non transponder usually has a thinner black head with hole in center top of key. Most 2003+ Fords are transponder EXCEPT 2005 Ranger & Super Duty Models. Some key manufacturers have application guides for free on their websites. ILCO, Strattec, and JMA are a few manufacturers.
