Top Reasons to Get Xhorse VVDI BE Key:

1. VVDI BE key support both 315mhz and 433mhz, you can change frequency via VVDI MB Tool software or remove the resistor.
2. Use BE Benz key, it is free with 200 points(equal 1 BGA Token).

Xhorse VVDI BE Key Pro Features:

More compatibility
New design
High Stability
High reliability
Digital Signature

VVDI BE key Pro improvements:

1. Fix the bug that W164/W639 EIS data doesn't synchronize the key.
2. Fix the bug/fault that the BE key stop work after repeatedly turn ON the ignition without removing key out from EIS/EZS for example with work on diagnostic...switch IGN OFF---ON for erase faults...then car not start
3. Fix the bug/fault of trunk remote open on cars where power lifts on trunk door mainly...
4. Fix the bug that the BE key only sent RF signal for one time, after the update, the RF signal can be sent for two times when press and release the key.
5. Modify the rolling algorithm, fix some errors of BE key.
6. Add the pre-roll algorithm: the HASH value can roll ahead.
7. Adopt car-grade quartz crystal, improve infrared communication stability.
8. Boost the infrared signal when you press the button.
9. Support resetting the key frequency between 315MHZ and 433.92 in the way of VVDI MB tool or the PCB SMD resistor

Tip: VVDI MB tool has priority over the SMD resistor, which means if you reset the key frequency with the VVDI MB tool at first, the SMD resistor won't work, and you need to use the VVDI MB tool to erase the frequency then use the SMD resistor.


How to assemble the case with VVDI BE key Pro improved version board?

This post shows the general guide on how to assemble VVDI BE Key Pro improved version with the Smart Key Shell 3 Button for Mercedes Benz.

1. Put the VVDI BE key Pro improved version PCB into the case.



2. Cover the bottom case.


3. Insert the battery and cover the case.


4. Push the metal strips on both sides into the right position.


If the rear metal component is first assembled, then the metal strips on both sides won't be able to pushed into the right position.

5. Here the rear metal button.


6. Put into the small key and start button.



If you want to disassemble the case, please do it from the last step to the first step.
