VVDI Key Tool Plus Unlock BMW CAS4 and Read ISN via OBD

 In this guide, we’ll walk through the process of performing an add key procedure on a 2015 BMW X3 using the Xhorse VVDI Key Tool Plus. This includes unlocking the CAS4+ module, reading the ISN number, and programming a new dealer key. Proper voltage maintenance and attention to detail are critical for success.

Tools and Preparation

• Xhorse VVDI Key Tool Plus (KTP)

• Battery maintainer (recommended voltage: 13V or higher)

• Original key

• New blank key

• Working internet connection (for data transfer)

Important Note: Ensure the vehicle battery voltage remains above 13V during the entire process. Operating at 12V or lower risks failure or module damage.

Step-by-Step Procedure

1. Read Vehicle Information

• Connect the Key tool plus to the OBD port.

• Turn on the ignition and scan the vehicle to retrieve the VIN and confirm the CAS4+ system.

• Verify the displayed information before proceeding.

2. Unlock the CAS4+ Module

• Save the module data file before starting the unlock process.

• Follow the tool prompts to transfer and receive data. This step may take time; avoid interrupting the process.

Tip:

• For stability, perform this step on a bench if possible. If using OBD, ensure a stable power supply and internet connection.

3. Read the ISN Number

• Insert the original working key (if available) into the key reader coil.

• Select the option to read the ISN from the key. The tool will display the ISN number.

• Record the ISN for future reference.

Alternative:
If no working key is available, the ISN can also be read from the engine control module (ECM).

4. Prepare and Program the New Dealer Key

• Navigate to the “Prepare Dealer Key” option in the tool.

• Select the key position (e.g., key number 5 if slots 1 and 2 are already taken).

• Choose the appropriate option (with working key or ISN, depending on availability).

• Place the new key near the coil and follow the prompts to program it.

Key Learning:

• Hold the new key close to the coil during programming.

• Confirm the “Learn Successful” message before testing.

5. Test the New Key

• Remove all other keys from the vehicle to avoid interference.

• For the first start, hold the new key near the ignition coil and start the engine.

• Verify that the engine starts and the remote functions (lock/unlock) work properly.

Important Tips

1. Voltage Stability: Always use a battery maintainer to keep voltage above 13V. Low voltage can cause failures.

2. Data Transfer: A strong internet connection ensures smooth communication with the server during CAS unlocking.

3. Key Positioning: Proper placement of the key on the coil is critical for successful programming.

4. Backup Data: Save all module data files before making changes for recovery purposes.
