Immobilizer question, bcm
 

Is the bcm partof the immobilozer communication on a 2013 non smart key car. I have installed a ecu (untuned), a cluster and a steeri g stalk with immobilizer amplifier and original key, all from the same car in order to get my car to start. After the changes i still get the security key blinking on the cluster. If i install a bcm from a non smart key car, will that solve my security/immobilizer issues. I have performed the key relean a few times with no luck
Thanks
