How to program a new key to Audi A4 B8 the 2009 year, using Xhorse VVDI2 ? What is procedure if all keys are lost?
Reply: Same as for adding key, the only difference is that at some point you have to disconnect the BCM2 power and reconnect it. Just read the instruction below.
I would recommend take out BCM and read BDM file with VVDI2 BDM cable . Then load file, make dealer key and learn keys .
1.Connect VVDI2 with computer and your car.
2.Put the new key into VVDI2.
3.Start VVDI2 software,and choose Audi.
4.Click on “Key Learn>>5th immobilizer system”.
5.Read BCM Data (OBDII).
6.Insert a working key to turn on ignition before continue.
If the key is already in car, you also need to remove it then insert it again.
If you lost all keys, you need to open car headlight and step on the brake before continue.
7.Read data success, save the eeprom bin file.
8.Make Dealer Key.
If car is A4/A5/Q5, press YES button to continue, no need working key.
If car is A6/A7/A8/VW Touareg, press NO button because it needs working key. Click on YES.
9.If you want to program an OEM key, make sure the new key support change ID. Click on YES.
Choose Auto Key Programmer normal dealer key option, click Next and OK to load the BCM file.
10.OK and VVDI 2 start to program new key.
Wait a minute and VVDI2 make new dealer key successfully!
11.Change key number from 1 to 2.
Click on Key Learning then OK to load the BCM bin file.
VVDI2 start learn key.
Use the working key to turn on ignition then insert the new key to learn.
