How would I reset the ECU or the NON-OEM SO the key would work for my 2001 ford expedition

My car has 160000 miles.
My car has an automatic transmission.

Hi Shakaira. The ECU would need to be reprogrammed by a Ford dealership. If you have a non-OEM key or ignition system, it will be difficult to have it link to the ECU. You might want have a professional mobile mechanic come to your location to complete an onsite inspection so they have a better understanding of your situation and recommend the right course of action.
