When you warmed the mcu, did the key turn to ignition?
Ill check the dumps once I arrive at office.
Did you program flash in the new mcus or did they come from another ezs and same positions?

Well thats weird, did you check the used ezs before opening it?

I had a case like this a few days ago. When used ezs arrived i tested first, then cloned both eeproms and made keys and its good to go.
