Hello, they are absolutely correct to a point. every ME_SFI control unit gets coded once installed, we call it "marrying" . once its removed and installed into another car the trans module and ignition switch will reject the drive authorization do to the mismatch of the vin numbers. so you must replace the ecm with a new uncoded one. is your vehicle out of warranty or something? cause engine control units are covered for 8 years 80k miles under warranty. now the grey area is there are companies out there that can code your module for you, i dont know how they are able to achieve this but if you google and search you will find a handful of companies that can do that for you. hope this helps, Lou p.
