slowmoe,
Was the replaced module the IRCL or the ME/HFM fuel computer?

I am working from memory but the IRCL sends a signal to the ME and the ME must release the progaram to allow the car the start. 90% key related, but not when all keys act the same. 9% IRCL (module behind the instrument cluster) 1% Fuel computer. The diagnostics on this inbetween protection system are very scary.
I will check this info after I return following the Presidents Holiday.
