MBSeedKey is a Windows utility designed to work with Seed and Key algorithm libraries used in Mercedes-Benz diagnostic and engineering environments. It helps technicians organize a folder of SeedKey DLL files, search by DLL name, and view the associated ECU profile details such as ECU name and available access levels.



The interface is built around selecting a SeedKey DLLs folder, filtering the library list, and inspecting metadata for the chosen entry. This is useful when multiple ECU families and security levels exist, and you need to confirm the correct algorithm library is selected for an authorized diagnostic session.

Highlights

• SeedKey DLL folder selection with a dedicated button to change the library path
• Search field to filter DLLs by name for faster ECU profile discovery
• Per entry details panel showing ECU Name, Access Levels, and Comment fields
• GUI and CLI executables included for workstation and scripted workflows
• Portable Qt based runtime layout with required platform plugins and translations
• Bundled Visual C++ redistributable installer for compatible Windows setups

Compatibility notes

• Supported ECUs and access levels depend on the SeedKey DLL set you have and how it is licensed for your environment
• If the wrong DLL is selected, the displayed ECU details may not match your target module and results can be invalid
• Use only approved, lawful workflows for security access and follow OEM documentation and local regulations
• Do not share proprietary DLL libraries or vehicle security data without permission

Basic usage

• Install prerequisites if required by your Windows build, then launch the GUI or CLI
• Set the SeedKey DLL folder to the directory that contains your authorized algorithm libraries
• Search by DLL name to locate the relevant ECU family entry
• Review ECU Name, Access Levels, and Comment fields to confirm you selected the intended profile
• Use the tool only within authorized diagnostic procedures and keep audit logs for workshop traceability
