4. Detailed Steps for Performing Key Adaptation with VCDS
Here’s a detailed step-by-step guide for performing key adaptation with VCDS. Note that the exact procedure may vary depending on the vehicle model. Always refer to the Ross-Tech website or the vehicle’s service manual for specific instructions.
4.1. Prerequisites
- VCDS diagnostic tool
- Compatible key
- Vehicle’s PIN code (SKC)
4.2. Procedure
- Connect VCDS: Connect the VCDS tool to the vehicle’s OBD-II port and turn on the ignition.
- Select Control Module: Open VCDS and select the “Immobilizer” control module (usually address 25).
- Login: Enter the vehicle’s PIN code (SKC) to access the adaptation functions. This step is crucial as it unlocks the security features of the immobilizer.
- Adaptation: Select the “Adaptation” function.
- Channel Selection: Enter the adaptation channel number for key adaptation. This is typically channel 01.
- Read Value: Read the current value in the channel. This value indicates the number of keys currently adapted.
- New Value: Enter the new value, which should be the total number of keys you want to adapt (including the new key).
- Save: Save the new value.
- Key Adaptation: Follow the on-screen prompts to adapt each key. This usually involves turning the ignition on with each key for a specified period.
- Test: Test each key to ensure that it starts the vehicle.
4.3. Example: Audi A4 (B6) Key Adaptation
As indicated by the original post, the following steps can be used as a guideline, but always verify with official documentation.
- Connect VCDS to your Audi A4 B6 via the OBD-II port.
- Navigate to 46-Central Conv. and then to Adaptation.
- Check Channel 21
- The initial value might be misleading. To start fresh, enter 0 and save on channel 00 to clear any existing entries.
- Proceed to channel 21 and increment the value to 1. This prepares the system to recognize the first key. VCDS should automatically test the value if you are using the arrow keys.
- Instead of hitting Save as some guides suggest, press and hold the Unlock button on your remote key for about a second. The display should confirm that the key is learned or registered.
- Increment the channel value again (to 2) to prepare for the next key. Repeat the unlock button process for each additional key.
- After all keys are registered, that’s the point where you hit Save.
- Test each key to ensure it works properly.
