Effective Date The new authentication requirement will take effect on: May 25, 2026

From this date onward, all SFD activation and unlocking procedures on supported VAG vehicles will require identity verification through Google Authenticator.

What Has Changed? To improve security, VAG now requires an additional verification step before granting access to protected functions.

Mandatory Two-Factor Authentication Google Authenticator has been integrated into the SFD unlocking workflow. Users must verify their identity before protected vehicle functions can be accessed.

Dynamic Verification Codes Each SFD unlock request requires a temporary six-digit code generated by Google Authenticator. Without a valid code, the unlock process cannot proceed.

One-Time Device Registration Users who have not previously linked their device will be prompted to complete a one-time setup process during their first SFD activation after the update.

How the New SFD Verification Process Works Step 1: Start SFD Activation Begin the normal SFD unlock procedure on your LAUNCH X431 diagnostic scanner.

Step 2: Link Google Authenticator During initial setup, a QR code will appear on the screen. Open the Google Authenticator app on your smartphone and scan the displayed QR code to establish the connection.

Step 3: Obtain Verification Code After linking the device, Google Authenticator will automatically generate a temporary six-digit security code.

Step 4: Enter the Security Code Input the generated code into the verification field on the LAUNCH device and confirm the operation.

Step 5: Access Granted Once verification is successful, the SFD protection is released and the diagnostic session can continue normally.

To avoid delays during service, make sure:

Your LAUNCH X431 software is updated

Google Authenticator is installed on your smartphone

Device registration has been completed before arriving at the vehicle

This update affects all technicians performing SFD-related diagnostics and programming on newer Volkswagen Group vehicles. Completing the setup in advance will help ensure a smoother workflow during future service operations.

If your Launch X431 PAD VII Elite appeared “The diagnostic software file is lost or damaged. You are advised to delete the software and download it again”, please follow the method below to solve it.

Possible cause: Losing the software on X431 PAD VII (PAD7) is a common headache, usually caused by a system crash, an accidental deletion of the cnlaunch folder, or a factory reset.

Solution: The good news is that your licenses are tied to your device's Serial Number (S/N), so you won't have to pay to get them back.

Here is the step-by-step process to restore your diagnostic capabilities.

1. Reinstall the Main Application (X-431 APK) If the actual X-431 icon is missing from your home screen, you need to reinstall the "shell" app first.

Most PAD VII tablets have a built-in recovery app.

Open it, enter your 12-digit Serial Number, and tap OK. It will automatically fetch and install the correct version of the diagnostic app for your hardware.

2. Log In and Restore Vehicle Brands Once the app is open, it will likely be empty. You need to pull your licenses from the Launch server.

Tap Login (top right corner). Enter your Username and Password.

Note: If you've forgotten these, use the "Retrieve Password" function. You will need your Serial Number from the back of the tablet.

Go to the Software Update (or Upgrade) module. The tablet will query the server and show a list of all vehicle brands (BMW, Toyota, Ford, etc.) that you are licensed to have.

Tap Update All (or Select All then Download). This may take a while depending on your internet speed, as it is downloading several gigabytes of data.

3. Clear the Cache (If software is "missing" but installed) If the app is there but behaves strangely or claims software is missing, the local database might be corrupted. Go to User Info (or Profile) -> Settings. Select Clear Cache. Restart the application and check the Software Update section again.

Important Troubleshooting

"Activation" Prompt: If the app asks for an activation code, it means you aren't logged into the original account. You only use the activation code once during initial setup. After that, your S/N is bound to your username.

VCI Connection: After reinstalling, make sure to plug your Smartlink C VCI into a vehicle and the tablet to ensure the Firmware Fix/Update runs. This syncs the tablet software with the connector hardware.

Storage Space: Ensure you have at least 20GB of free space before hitting "Update All," or the installation will fail halfway through.

Car key programming might look complicated at first glance, but with the right knowledge and tools like KEYDIY KD-X4, even beginners can quickly learn and apply the process. This guide explains the basics and helps you understand how car key programming works in a simple way.

What is Car Key Programming? Car key programming refers to synchronizing three key components of a car key with the vehicle:

With the help of tools such as KD-X4, this process becomes much easier and more efficient.

Among these options, KEYDIY KD-X4 is well known for its reliable chip reading and key generation functions.

Basic Workflow of Car Key Programming The general process includes three main steps:

Cut the mechanical blade Program the transponder chip Sync the remote control

Using KEYDIY KD-X4, tasks such as chip reading, data generation, and key writing can be completed smoothly.

Two Common Programming Scenarios Scenario 1: Adding a Key (When You Have an Existing Key)

This is the simplest case: Duplicate or cut the mechanical blade Use KEYDIY KD-X4 to program the chip and remote Successfully add the new key

Scenario 2: All Keys Lost This situation involves additional steps:

Unlock the vehicle using locksmith tools Decode the lock Cut a new mechanical key Program the chip and remote with KEYDIY KD-X4

Although this process is more complex, it can still be handled effectively with the right tools and proper steps.

Conclusion Car key programming is not as difficult as it may seem. Once you understand the key components and follow the correct workflow, tools like KD-X4 Locksmith’s Universal Tool will help you complete the job efficiently and professionally.

DUCATI PIN code is a 4-digit security password. Its primary function is to serve as an emergency unlock credential for the Immobilizer System (IMMO) and to facilitate critical anti-theft data programming.

1) If the key transponder fails, the fob battery is dead, or the vehicle experiences an immobilizer malfunction or lockout, the PIN must be entered via the dashboard to unlock the vehicle ;

2) Factory default PINs are often generic (e.g., 0000 or a specific combination) and can be modified via the instrument cluster menu to a personalized code, preventing unauthorized access ;

3) If the PIN is not stored correctly or is lost, the vehicle may be restricted from starting, or the dashboard menu may prevent changes. In such cases, OBDSTAR MOTOMASTER 's [PIN Code Reset] function is required to resolve the lockout.

Preparation: MOTOMASTER, M001A, M041.

Solution: Use OBDSTAR MOTOMASTER to perform [PIN code reset] function to reset PIN code.

3) Select the [PIN CODE] function from the menu ; 4) Enter the reset PIN: 0000 ; 5) Set a new PIN to complete the modification.
