The anti-theft PATS system is mainly controlled by the instrument cluster. This is where the Key info is stored. Since you haven't changed the cluster, there is no need to reprogram the keys. The Instrument cluster and the ECM are a matched pair and that is why your's will not start. You will need to perform a "parameter reset" to resync up your new ECM to your Cluster. It looks like you will need a NGS tester or equivalent (Dealer) to do this.
