Xhorse VVDI BE Key Pro Improved Version

Notice: The board version is V3.1, V3.2, or V3.3—shipped randomly.

This is a PCB only without case.

1 VVDI BE Key Pro Improved Version = 200 VVDI MB BGA Tool Points = 1 VVDI MB BGA Token. Please obtain the token yourself in the APP.

Features of Xhorse VVDI BE Key Pro

VVDI BE Key Pro Improvements

1. Fixes the bug where W164/W639 EIS data doesn't synchronize with the key.
2. Resolves the issue where the BE key stops working after repeatedly turning the ignition ON without removing the key from EIS/EZS (e.g., during diagnostic procedures involving IGN OFF/ON cycles to erase faults, which previously caused the car not to start).
3. Fixes the trunk remote open malfunction on vehicles with power lift trunk doors.
4. Corrects the issue where the BE key only sent an RF signal once; after the update, the RF signal is sent twice upon pressing and releasing the button.
5. Modifies the rolling algorithm to fix certain BE key errors.
6. Adds a pre-roll algorithm: the HASH value can now roll ahead.
7. Adopts a car-grade quartz crystal to improve infrared communication stability.
8. Boosts the infrared signal when the button is pressed.
9. Supports resetting the key frequency between 315MHz and 433.92MHz via the VVDI MB tool or the PCB SMD resistor.

Tip: The VVDI MB tool takes priority over the SMD resistor. If you reset the key frequency using the VVDI MB tool first, the SMD resistor will no longer function. To use the resistor, you must first erase the frequency setting via the VVDI MB tool.

How to Reset Frequency Using the PCB SMD Resistor

Weld the 1K SMD resistor at the position indicated by the arrow to set the frequency to 315MHz. Removing it sets the frequency to 433.92MHz.

How to Assemble the Case with VVDI BE Key Pro Improved Version Board

This guide shows how to assemble the VVDI BE Key Pro Improved Version with the Smart Key Shell 3 Button for Mercedes Benz:

1. Insert the VVDI BE Key Pro Improved Version PCB into the case.
2. Cover the bottom case.
3. Insert the battery and close the case.
4. Push the metal strips on both sides into the correct position.
   Note: If the rear metal component is assembled first, the side metal strips cannot be properly positioned.
5. Attach the rear metal button.
6. Insert the small key and start button.

To disassemble, reverse the steps—from last to first.

Note: If the rear metal component is assembled first, the metal strips on both sides won’t fit into the correct position.
