Key Matching with 7-digit SKC

This procedure details how to match new keys to Immobilizer-equipped VW/Audi vehicles. As of 11 Mar. 2002, VW and Audi are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code) method unless the owner still has the correct 4-digit code.

Procedure for matching keys to vehicles with Immobilizer in the Instrument Cluster:
(includes many 1999+ Golf/GTI/Jetta/New Beetle/Passat, also Audi)

1. [Select] 
   [17 - Instruments]
   Write down the 14 digit Immobilizer ID number from the "Extra" field
    

2. Take that ID number to your dealer and request your seven-digit SKC, along with the workshop code and importer number (all this information can be found in the upper-right corner of the Administration screen of the dealer's VAS 5051).
    

3. [Select]
   [17 - Instruments]
   [Login - 11]
   [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]
    

4. 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!]
    

5. [Adaptation - 10]
   Enter 21 in "Channel Number"
   [Read]
   The "Stored Value" is the number of keys currently matched.
   Enter "new value" of 0
   [Save]
   This clears out the old key-matchings.
   Enter a "new value" corresponding to the total number of keys to be matched,  including any existing keys
   [Save]
    

6. [Done, Go Back]
   [Close Controller, Go Back - 06]
   Switch ignition off and remove key
    

7. 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
    

8. Repeat step 7 with each key until all keys have been matched.
