Always make a backup first and have a battery maintainer under the charger. Otherwise will brick car.
The safest way is done on bench.
Always on istap remove CAS and read eeprom and Flash to be save, then with eeprom dump write key on vvdi2. On all keys lost you will need ISN from ECU that many tools can read on bench .

Bench always safer than obd because you can backup and save your data.
