Key Matching


  • All keys are either new or were adapted to this car (IMMO-ID) before.
  • You can match up to 4 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 001.
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.
[Done, Go Back]

[Login - 11]
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]
    • VCDS 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 01 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 the next Key and switch Ignition ON.
    • The Immobilizer Warning Light will light up for ~2 seconds, wait until it goes out.

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