Line up the ECU specifiers that don't include battery backup or non volatile RAM in the specification up against a wall, and shoot them, pour encourager les autres.

Keys out of ignition- disconenct the battery again for at least 10mins.
Reconnect. Try again.
If still no joy- try the spare key.
If still not, then the ECU has forgotten the correct code, or has been internally damaged from a spike. How did you re-charge battery?
