I have managed to program a new dealer key for VW’s 4th generation immo NEC24C64 using Xhorse VVDI2 and VAG OBD Helper cable.
With the VAG OBD cable, I can easily handle VW all key lost situations via OBD II.
- Support A4L Q5 (all the card 754C/J type).
- Can perform all keys lost or add a key for VW, Audi, Skoda 4th generation dashboard.
- Capable of adding a key for MQB JOHNSON dashboard (please note that do not support all key lost scenarios).
- Can handle new PASSATT MQB allkey lost situations.
- Support obtaining BCM2 immo data online for A6 A7 A8 Touareg 5th generation.
- f) The VAG OBD cable can be used with various programmers such as VVDI2, Lonsdor K518ISE, SMOK APPRO, and more.
Now, let’s get into the step-by-step process of using Xhorse VVDI2 and the VAG OBD Helper:
Connect the VAG OBD Helper cable to the vehicle, reading immo data
Use the remote to operate the vehicle’s immobilizer and select the VW immo type as IMMO4 – Magneti Marelli Motorola.
Choose the online key ID and perform online calculation to obtain the immo data. It’s important to note that this immo data is not the full immo data, so it should not be written back to the car using other tools.
Save the immo data and be aware that you can prepare a new dealer key and learn key with this immo data using another immo device.
Press “OK” to automatically open the immo data folder.
Now, let’s move on to VVDI2 VAG software:
Prepare a normal dealer key, but remember to manually select the car manufacturer before proceeding.
If you choose to make a dealer key with a normal key, please note that it does not support online change immobilizer.
I recommend selecting OEM instead. The OEM dealer key has the same ID as the original key and supports online operation.
Keep in mind that online operation cannot support certain units, including：
01 – engine
02 – gearbox
17 – instruments
19 – can gateway
28 – electrical steering column lock
Again, I advise selecting OEM for optimal results.
To create a VW normal dealer key, ensure that the brand is correctly selected.
Now, let’s check a few details:
Do you have a working key to start the engine? If yes, we can proceed.
If you want to lock the key, please note the following steps: First, try preparing a dealer key with the UNLOCK option, and then perform the learning operation. If the unlocked key can be learned by the car, you can prepare that key again with the LOCK option (please note that the key cannot be used in other cars after it’s locked).
Finally, insert the new key into Xhorse VVDI2, and prepare a dealer key successfully!
Congratulations! The job is done, and your new dealer key is ready to be used.
