wks with 6.0.3.837 edition can be activated by the activate code alone, is there any relevant way to activate the groups by activation code from the administration kit??(I know that we can activate by a key file from the administration kit traditionally)

Doesn't anyone know??any engineer here?

No, unfortunately you need "a key" for remote WKS key deployment. You can convert your code into a key here:
