VVDI BE key Pro PCB +case, where to buy?

VVDI BE key Pro improved version is tested working flawlessly and available for sale, the following parts include VVDI BE key Pro update info and change Mercedes Benz key frequency with VVDI MB tool or or who not have this tool, then keep the way through PCB resistor.

VVDI BE key Pro highlights:
More compatibility
New design
High Stability
High reliability
Digital Signature

VVDI BE key Pro fix some bugs/ faults:

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. VVDI BE key Pro supports change key frequency Mhz 315 or 433 through SW of VVDI MB tool or who not have this tool, then keep the way through PCB resistor.

Here we go in the both method to change Mercedes Benz key frequency

Option 1: change key frequency 315 MHZ or 433MHZ with PCB resistor

Put the VVDI BE key into the device programmer of VVDI 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.

Option 2. change key frequency 315 MHZ or 433MHZ with VVDI MB tool 

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

00:14 - 00:018 : 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.
