How to test VVDI BE Key Pro frequencey

Had good successs with frequency test of VVDI BE key pro improved version, frequency between 315Mhz and 433Mhz, tested with and without VVDI Mercedes software

This is how to test VVDI BE Key Pro frequencey…

For those have no VVDI MB:

You can change key frequency 315 MHZ or 433MHZ with removal of a PCB resistor

Put the VVDI BE Key to the VVDI MB BGA TOOL to test the key frequency

 

This is a complete new BE key unused.

Test the frequency with VVDI key tool, it is 315MHZ.

Here is a square resistor marked with “FRE”, just remove it.

Put the BE key into the VVDI key tool to read out 433MHZ frequency.

For those have VVDI MB TOOL:

You can change key frequency 315 MHZ or 433MHZ with VVDI MB tool

Open VVDI MB tool, Enter Menu -> Other functions -> reset key frequency.

Click on ” Read out key frequency”, the result is 315MHZ.

Put the VVDI BE key on the top of the VVDI KEY TOOL and the key frequency is 315MHZ.

Insert the VVDI BE key into VVDI MB tool.

Choose” 433MHZ” then “Change key frequency”, reset successfully.

Put the VVDI BE key on the top of the VVDI KEY TOOL and read out 433MHZ.93.

Insert the VVDI BE key into VVDI MB tool and you can see ” the key frequency is 433MHZ.93″, click “OK” to confirm.

Explanation to the option “through PCB resistor”. who don’t have VVDI MB tool, then change the key frequency through PCB resistor.

Xhorse VVDI BE Key Pro Improved Version for VVDI MB and Other Tools Support Benz XNBZ01CH Remote Key Chip

XHORSE VVDI BE Key Pro For Benz XNBZ01CH Remote Key Chip Improved Version

VVDI BE key Pro improved version 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 that the BE key fails to turn on the ignition after repeat try.
3. Fix the bug of trunk remote open 
4. Fix the bug that the BE key only sent RF signal for one time, after 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 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 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.



Package includes:

1pc x VVDI BE key Pro improved version (PCB only without case)
