The 7-digit PIN/SKC (Secret Key Code) dialog is used for Key Matching and Immobilizer 3 Adaptation. See this page for instructions for each procedure and immobilizer type:

Common Diagnostic Procedures

You must enter the following information:

7-digit SKC that the dealer generated for your exact Immobilizer ID Number.

Date on which the 7-digit SKC was GENERATED BY THE DEALER.

Workshop Code (WSC) for the dealer that generated the SKC.

Importer Number for the dealer that generated the SKC.

The 7-digit SKC is useless without the other three items.

When you have filled in all of the data click [OK]. If any of the entered data does not make sense, the following message may appear:

vagcom error

When you have successfully submitted the 7-digit PIN/SKC, you are taken back to either the Login or Adaptation screen (wherever you were when you clicked on [Use 7-digit PIN/SKC] ). Now, you should have XXXXX in Login or Adaptation value.


Unlike the factory diagnostic tools, with VAG-COM, the same PIN can be used for a particular car at any time in the future, as long as you keep track of the PIN, along with the Date on which the PIN was GENERATED BY THE DEALER, the dealer's Workshop Code (WSC) and the Importer number.

If you obtain a 7-digit SKC, but the dealer has not provided the WSC, look at the window stickers of vehicles on the dealer's lot. The dealer number will be listed next to the name and address of the dealer. In the US, the dealer number will be a 4 followed by five more digits, for example 401742. To obtain the WSC, delete the 4 and simply use the remaining five digits, 01742 in the above example.

The Importer number should be:

444 for all dealerships in the US
999 for all dealerships in Canada
995 for all dealerships in France

Use the [OK] button to save the 7-digit information and return to the Login or Adaptation screen

Use the [Cancel] button to return to the Login or Adaptation screen without saving.
