Here is the instruction on using FVDI2 VAG commander key programmer to program a new key to Audi A6 MY2013 when all keys lost.


You can read BCM2 P flash and D flash by Orange 5 eeprom programmer or CG100 flash programmer.

Before doing all key lost, the key has been prepared to the dealer key and learned to the car, but cannot turn ignition ON or start the engine.


Start FLY OBD Terminator, select Immobilizer from the main menu, then VAG/KeyMaker/Audi A6 A7 A8 Touareg


Load BCM2 P flash and D flash (EEPROM)


There are 3 scenarios you can select:

1- have a working key

2- have a ELV dump

3- have the decoded ISK file

If all key lost, you should select option 2 (have a ELV dump)


Put the key into the coil

Data log finished!

Save the logo data as a file.

Usually, it needs 30 minutes or less

For this car, it takes 12 minutes to decode

At last, 32 bytes ISK decoded successfully!
