The manipulation dot (tamper dot) illuminates when the IKE (instrument cluster) and the LCM (light/lamp control module) don't have the same VIN. Are you sure its the immobilizer or are you confusing that with the LCM?

See datapoint #1 in the info below about redundant data storage (between the IKE & LCM):
