Hi im really struggling to learn to add a key to a BMW X6 2009... 
In all cases the car still works perfectly with the original key it has.

My experiments:

All read/write CAS3+ MCU eeprom with Xprog ( OK, tested several times)

FVDI Clone==> Tried to do it all by OBD, failed.
Tried loading cas eeprom to key maker==> Result made Key then wrote file to CAS3. The remote unlocks/locks the car but doesnt unlock the dash/ start car.

Hitag2 Clone==>Loaded cas eeprom=>Made Key=>Wrote File to CAS3.
Resulting again in key remote only locks/unlocks the car.

Tango Clone==>Loaded cas eeprom+DME dump=> Made Key=>Wrote File to cas3 ==> Key remote doesnt even lock/unlock car.

Reading the Key tango made, it didnt even record the VIN ¿? although it did change to Locked State.
I ordered new blank keys, maybe those keys where bad?¿

AutoHex II/BMW Explorer are out of my price range.

So what would be the best option to cover cas3 and cas3+ ?¿

-Xhorse Multitool ( I read good reviews although i think i would have to downgrade the cas3 versions and leave them downgraded?).

BMW ISTA-P Clone ( Does this make Keys? or only diag & coding units)

TMPro2 Original + Software 130 BMW,Mini CAS SiemensVDO ?

Thanks
