Preparation for Key Programming

Before diving into the key programming process, ensure you have the following equipment ready:

• 12V Power Supply (for powering the adapter)
• Working Key (if available, helps with sync data)
• New Blank Key (for generating the dealer key)

Step 1: Connecting the Device and BDC2 Module

The first step is to connect the Xhorse BMW BDC2 Adapter to the vehicle's BDC2 module. This module is typically located behind the glovebox or dashboard. Follow these steps:

1. Locate the vehicle’s BDC2 module.
2. Align the Xhorse BMW BDC2 Adapter with the three positioning pins to ensure a secure fit.
3. Connect the VVDI2 device to your computer via USB.
4. Link the BMW-G BDC2 Adapter to the VVDI2 device.
5. Power the adapter using a 12V power supply and press the power switch.
6. Confirmation: A white LED will light up, indicating a successful connection.

Step 2: Reading BDC2 IMMO Data

Now that the devices are connected, proceed to read the IMMO data:

1. Open the VVDI2 Software and select the BMW option.
2. Navigate to Key Learn and select G Series BDC Key Learn.
3. Click the Get Key Info button and wait for the system to read the data automatically.
4. Select Read G-Series BDC02 Security Data. This process is automated, requiring no further input.
5. Verify the wiring connections using the provided diagram and click Next to save the backup file in your preferred location.
6. Confirm entry into Service Mode; a success notification will appear.
7. The system will automatically read and save BDC Security Data. Ensure the file is saved as it is needed for key generation.

Step 3: Generating a Dealer Key

With the IMMO data secured, you can now generate a dealer key:

1. Exit the BDC reading interface and select Make Dealer Key.
2. Load the previously saved BDC key data file.
3. If you have the original key, click Yes to read sync data directly from the key. If no original key is available, click No and manually load the saved sync data file.
4. Place a blank key into the VVDI2 detection coil and click OK. The system will generate the dealer key.
5. Follow the on-screen prompts to complete the key learning process.

Upon successful completion, the new key is now ready for use.
