Adding a new remote key to your Volkswagen or Audi using VCDS can be confusing. While the official Ross-Tech guide offers helpful information, it might not always be accurate for all VCDS versions and car models. This guide provides a clarified, step-by-step approach to successfully add a remote using VCDS, based on practical experience with a 2002 Audi A4 B6 and VCDS version 409.1.
Locating the Adaptation Channel
First, connect your VCDS interface and launch the software. The key matching function is typically found within the Central Convenience or Central Locking module. For the 2002 A4 B6, it’s located under 46 – Central Conv. / Adaptation / Channel 21. Other models, like some Volkswagens, may have it under 35 – Centr. Locking / Adaptation / Channel 01. It’s crucial to confirm the correct channel for your specific car model. Use the VCDS function search if necessary.
Clearing Existing Key Entries (If Needed)
In some cases, you might need to clear existing key entries. Observe the current value in Channel 21. While the Ross-Tech guide suggests this value represents the number of matched keys, this might not always be accurate. If you have a working key but the channel displays “0”, proceed with clearing the entries. To do this, enter “0” in the channel value field and click “Save.”
Adding New Remotes with VCDS
With the entries cleared (or if clearing wasn’t necessary), you can begin adding new remotes:
-
Increment the Channel Value: In Channel 21, press the “Up” arrow key once. The value should change to “1.” The “Test” button will likely gray out as using the arrow keys automatically tests the new value. The display should indicate “KEY” and “ADJUSTING” (or similar wording).
-
Program the Remote: Contrary to the Ross-Tech guide for some versions, DO NOT press “Save” yet. Instead, press and hold the “Unlock” button on your new remote for approximately one second. The status should change from “ADJUSTING” to “LEARNED” or “REGISTERED.”
-
Repeat for Additional Keys: If you have more keys to program, press the “Up” arrow key again to increment the channel value (e.g., from “1” to “2”). Press and hold the “Unlock” button on the next remote until it registers. Repeat this step for each additional key.
-
Save the Changes: Once all keys are learned, and only then, press the “Save” button to finalize the programming.
Final Testing and Verification
After saving, test all the programmed remote keys to ensure they function correctly (locking, unlocking, trunk release, panic button). If any key doesn’t work, repeat the process for that specific key.
This refined guide addresses potential discrepancies in the standard Ross-Tech instructions for adding remotes with certain VCDS versions. By following these steps, you can successfully program new remote keys to your Volkswagen or Audi using VCDS. Remember to always double-check the correct adaptation channel for your specific car model.
