GM 5-byte seed-key generator tool

GM 5-byte seed-key generator tool


          GM 5-byte seed-key generator tool is designed to unlock GM controllers at security access level for programming (27 01)  to access critical diagnostic procedures and functions. Unlock challenges are sort of a question and answer game between the ECU and diagnostic equipment. To give the correct secret answer to an ECU question, you need a GM Seed-Key calculator that can calculate the correct answer. With the help of this software you can very easily use the full capabilities of DPS and SPS for GM.


This is a software activation. All current: 

  • Hyundai and KIA VIN to PIN calculator customers
  • Simplediag any software activation customers
  • SKGT customers


       can enable this function because they already have a security dongle. 


New customers who wish to purchase it and do not have a security dongle must purchase one along with the activation.



Security dongle - 50 euro 

Activation 6 - 300 euro
