The is a lightweight Windows utility designed specifically for professional service centers needing to synchronize immobilizer data after a hardware replacement. This tool operates on dump files loaded from modules, allowing technicians to safely pair a DME with a CAS during legitimate repairs. Its one-click workflow reads identifiers from the dumps, aligns the ISN, and performs a safe DME-to-CAS pairing, supporting a wide array of DME/DDE families (MS43, ME5.2.1, ME7.2, etc.) and EWS/CAS families (EWS4, CAS2, CAS3, etc.). As its developers note, this utility is intended for lawful service operations and should only be used on vehicles you are authorized to service.
