With the check engine light not coming on check and make sure no fuses had shorted out when the ECU was replaced as this will cause this fault here.If a fault is found with one or more of the fuses the affected fuses need replaced and then the vehicle re checked for proper operation and to see if you can then code the key.If no fuses are found to be blown let me know so we can continue.
