Adding a key for the Volkswagen Passat B6 using the Xhorse VVDI Key Tool Plus is a quick and straightforward process, accomplished entirely via OBD. This guide outlines the procedure in four simple steps, including free PIN code reading. Follow the steps below to learn how.

Important Notes:
① For the B6/CC/B7, you can read the engine ECU to obtain the PIN and a 6-byte CS code without needing the comfort module dump file.
② Adding a Key: The 7th byte of the CS can be obtained from a working key. For 46-chip keys, use FF for the 7th byte.
③ All Keys Lost: For 48-chip keys, try to make a dealer key. For 46-chip keys, use FF for the 7th byte.
④ Press "OK". A prompt will appear stating "Only support read PIN, CS, MAC now". Press "OK" again.
⑤ Switch the ignition OFF, then ON.
⑥ The login code will be successfully read.
Step 2: Generate Dealer Key

3. You will be prompted to input the 7-byte CS code and the 5-digit password.
4. Insert a working key into the VVDI Key Tool Plus programmer.
5. The 7-byte CS code will be found successfully. Record these bytes.
6. Run the software again and use the first option (7-byte CS is known, generate dealer key). Input the 7-byte CS code and the 5-digit password.

4. Press "OK" after completing the operation for all keys.
8. You can enter "Immo status" to confirm the number of keys learned in the system.

1. Navigate to: Select by type > Remote system > 46 central comfort system (CANBUS Magotan/CC) > Start programming > Program a remote.
2. Press the central lock button once.
3. Use an invalid (non-remote) key to turn on the ignition. (For smart keys: turn off the ignition, place the smart key in the sensing area, then turn the ignition on).
4. Remove the key from the ignition.
5. Press the UNLOCK button on the remote you wish to program for 1 second. Double flashing of the indicators confirms successful matching.
