          Mercedes Benz Seed-Key Generator Tool (MB SKGT)


SKGT

 

The Mercedes Benz Seed-Key Generator Tool (MB SKGT) was designed to unlock MB controllers in different levels to get access to critical diagnostic procedures and functions. The unlocking challenges are kind of a question/answer game between ECU and diagnostic equipment. To give the correct secret answer to a question of the ECU you need the MB SKG Tool, which is able to calculate the correct answer. This software is specifically designed to work with Vediamo and Monaco.

There are several access/unlock levels for any controller in vehicles:

  • Unlock level 01 – makes security access to level one

      Functions/routines: request seed ECU unlock (27 01)/send key ECU unlock (27 02)

      This is used in most ecu’s till Emission EU6 for general ECU Unlock for doing Variant coding, Adaption…

 

  • Unlock level 03 – makes security access to level three

      Functions/routines: request seed ECU unlock lev3 (27 03)/send key ECU unlock lev3 (27 04)

      Functions/routines: request seed adjustment (27 03)/ send key adjustment (27 04)

      This is used in most ECU’s to unlock adaption values like IMA/ISA, DPF/SCR/AGR /MAF values…

 

  • Unlock level 05 – makes security access to level five

      Functions/routines: request seed reprogramming (27 05)/send key reprogramming (27 06)

     This is used to unlock the ECU for reflash/reprogramming it  - attention – before ECU’s can give a seed for this functions

 

  • Unlock level 9A – makes security access to level 9

     Functions/routines: request Seed 9A (27 09)/send key 9A (27 0A)

     Functions/routines: request seed Unlock (27 09)/ send key unlock (27 0A)

     This is used as general Ecu unlock in newer ECU’s emission standard EU6 onwards. Mostly needs to be done first followed by another unlock for according special function.

 

  • Unlock level BC – makes security access level BC

      Functions/routines: request seed BC (27 0B)/send key BC (27 0C)

      Functions/routines: request seed Variant coding (27 0B)/send key Variant coding (27 0C)

      Is used in newer ECU’s emission EU6 onwards to unlock Variant coding

      These are the most common and used levels – different controllers may have different access levels, but working in same manner, also the output seed can have different length.

 

 

The software works with a USB dongle and the computer must have an Internet connection. This includes 10 Seed-Key calculations each day for 1 year. After the end of the year, a subscription will be paid for each subsequent year. We release new updates very often and all our software have automatic updates. Thus you can be sure you are always using the latest version of the app.
