You can get a good idea if you look at the number of keys programmed and number of keys required.
e.g. Keys programmed 3. Keys required 3.
This a a 4C...if the number was 2 then it is 4D. I was given this info below and up to now it has been accurate.
Escort - Red Ka - Red Early Fiesta (>96...(manufactured not registered)- Red Fiesta latest - Blue Focus ( tibbe key) Always Blue Mondeo Mk1/2 Always Red Mondeo Mk3 - Blue.
If in doubt try a red chip ( 4C) first
I find that Key programing on some vehicles is just the thing to get the old Sphincter muscle going....
