Hi everyone hope someone can help me out here. I have recently bought a mk3 fiesta 95 1.1lx. Somewhere along the way somebody has changed the ignition barrell so I have a red master key which does the door locks and 2 plain black keys non chipped and a fob with sawn off key with a chip in for the ignition. My question is how can I get all locks working with 1 key only? If it means I have to buy a full set of locks its not a problem but do I have to change the ecu as well? Or can I reprogram current ecu to work? Hope this makes sense lol.
