VVDI MB BGA Tool Program Keys on Mercedes E300 2010

Just done key programming on a Mercedes-Benz E300 2010 year by using VVDI MB BGA tool key programmer (software 2.1.7).

I have also done Mercedes W204 all keys lost with VVDi mb tool and it worked every time.
I have unlocked W204 ELV many times also. Sometimes it unlocks quickly and sometimes take long but it unlocks.
