Unlocking Vehicle Keys: A Guide to Using Xhorse MLB Tool MQB48 Adapter and Key Tool Plus

In the world of automotive technology, key programming and unlocking mechanisms have evolved significantly. Among the tools that have gained popularity among locksmiths and automotive professionals is the Xhorse MLB Tool MQB48 Adapter, paired with the VVDI Key Tool Plus. This article will provide a comprehensive guide on how to effectively use these tools through two distinct methods, ensuring you can unlock and program vehicle keys efficiently.

Understanding the Tools

The Xhorse MLB Tool MQB48 Adapter is designed to assist in programming MQB48 keys for a variety of vehicle brands, particularly those under the Volkswagen Group. When paired with the VVDI Key Tool Plus, a multifunctional programming device, locksmiths can perform key programming, IMMO functions, and more with ease.

Method 1: Direct Connection

This method involves a straightforward direct connection between the MLB Tool and the Key Tool Plus. Here’s how to do it:

1. Connect the Devices: Utilize a Dual USB-C splitter cable to link the Xhorse MLB Tool with the VVDI Key Tool Plus. Ensure that both devices are powered adequately.
2. Access the Menu: Navigate to the following menu path on your Key Tool Plus:
   • IMMO Programming
   • VW
   • Select by type
   • MQB instrument immo system
   • NEC35xx (Continental/VDO)
   • Collect Key data
   This function requires a stable network connection to proceed.
3. Complete the Process: Follow the prompts to collect key data from the vehicle's IMMO system.

Method 2: Using File Transfer

The second method is often preferred for its speed and efficiency. Here’s how to implement this method:

1. Calculate Key Data on PC: Use the Xhorse MQB48 Adapter and MLB Tool to calculate the MQB48 key data directly on your PC. This calculation is typically faster than using the Key Tool Plus.
2. Transfer Data: Once the IMMO data is calculated, save the file on your PC. You can then transfer this saved file to the Key Tool Plus using either a USB connection or through the Xhorse iCloud data center.
3. Load IMMO Data: On the Key Tool Plus, navigate to the MQB48 menu and load the IMMO data you transferred. From here, you can generate the dealer key and learn the key as needed.

Comparison of Methods

While both methods achieve the same end goal of unlocking and programming vehicle keys, it is recommended to use Method 2 for quicker processing. The PC software calculation is generally much faster than the Key Tool Plus Pad, making it the preferred choice for professionals who value efficiency.

Conclusion

In conclusion, the Xhorse MLB Tool MQB48 Adapter and VVDI Key Tool Plus offer versatile solutions for automotive key programming. By understanding and utilizing these two methods, you can enhance your locksmithing skills and improve the efficiency of your services. Whether you prefer a direct connection or file transfer, both methods have their advantages.
