This procedure details how to match new keys to VW/Audi/Seat/Skoda vehicles with Immobilizer III.

Determining IMMO-ID & VIN

[17 - Instruments]
or in vehicles with separate Immobilizer [25 - Immobilizer]
[Meas. Blocks - 08]
Look at the first "Extra" field. If you see something like: "Immo-ID VWZ7Z0W0648696" then you've got Immo-II (or maybe even Immo-1 in earlier non-US models).

If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" then you've got Immo-III. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.


[25 - Immobilizer]
[Meas. Blocks - 08]
Select Block 081.
The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID..

Key Matching


  • All keys are either new or were adapted to this car (IMMO-ID) before.
  • You can match up to 8 keys.
  • While adapting each key, make sure to place the other keys away from the ignition lock (reader coil). The passenger seat is an adequate place.
  • Battery voltage at least 12.0 V.

[25 - Immobilizer]
[Meas. Blocks - 08]
Select Block 002.
The value in field 3 must be 1. If value is not 1, the key is not capable of being adapted to Immobilizer.
You can check each key in this manner.

Select Block 003.
Make sure the shown lock times in field 1, 2 and 3 are 0 (each field represents a time in minutes).

  • If the lock times are NOT 0:
    • Do NOT switch off the ignition!
    • Allow the car to sit for AT LEAST the number of minutes that were indicated by the fields 1-3.

[Done, Go Back]

[Security Access - 16]
There are 2 possibilities how to enter a PIN, choose the one that applies for you.

  • 4-digit PIN
    • Enter zero followed by the 4-digit PIN. For example, if your PIN is 1234, enter 01234.
  • 7-digit PIN
    • [Use 7-digit PIN/SKC]
    • Enter the 7-digit PIN, Date on which the PIN was generated by the dealer, along with the Workshop Code (WSC) and the Importer number of the dealer that generated the code.
    • [OK]
    • VAG-COM will validate the data you have entered and return you to the Login screen, where the Login Code will show as "XXXXX".

[Do it!]

[Adaptation - 10]
Enter 001 in "Channel Number".
The "Stored Value" is the number of keys currently matched.
Enter a "new value" corresponding to the total number of keys to be matched, including any existing keys.
The old keys are automatically beeing cleared.
[Done, Go Back] [Close Controller, Go Back - 06]

  • Repeat the following steps until all keys have been matched:
    • Switch ignition off and remove key.
    • Insert next key to ignition and switch ignition on again.
    • The warning light for the Immobilizer will light up for ~2 seconds, then go out Switch ignition off and remove key.

Note: The above steps after saving the adaptation, should not exceed 60 seconds!
