The ways to reset the frequency:
1) with the PCB SMD resistor.Weld the 1K SMD resistor on the position the arrow points and the frequency is 315MHZ, after remove it will be 433.92MHZ.
2) Change frequency between 315MHz and 433MHz with VVDI MB Tool.
Check detail guide here: How to Change Benz VVDI BE Key Pro Frequency?
There are 2 ways to change Xhorse VVDI BE key frequency between 315 MHZ and 433MHZ. Xhorse BE key is designed to work with VVDI MB Tool and other MB key programmers
1: Change VVDI BE key frequency with PCB resistor

2. Change XHorse BE key frequency with VVDI MB Tool
In VVDI MB software, selectSet key remote frequency.
Choose433MHzandset frequency
Change frequency to 433MHz success
Xhorse VVDI BE Key Pro Features:
More compatibility
New design
High Stability
High reliability
Digital Signature
High quality with a reasonable price
No points will be accumulated
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
Note: 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:
1pcs x VVDI BE key Pro yellow/Green version with or without Key Shell

How to Change Xhorse VVDI BE Key Pro For Benz PCB Frequency?
XHORSE VVDI BE Key Pro For Benz XNBZ01CH Remote Key Chip Improved Version default frequency is 315MHZ,it supported to change frequency to 433mhz. Here we will introduce two ways to change Xhorse For Benz Key PCB frequency.
Method 1.Remove PCB FRE resistor change to 433MHZ.
Method 2.Change Via VVDI MB Tool Software.You can use VVDI MB software check key frequency firstly in EIS Software,other function set frequency.Then it shows 315mhz when you read frequency.Choose 433mhz to set,and check frequency again.
How to assemble the key shell with VVDI BE key board?
Here shows the general guide on how to assemble VVDI BE Key Pro imrpoved version with the Smart Key Shell 3 Button for MercedesBenz.
1.Put the VVDI BE key Pro improved version PCB into the case.

3.Insert the battery and cover the case. ( note: the package is without battery, need to buy it by yourself . )
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 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.
Note: If the rear metal component is firstly assembled, then the metal strips on both sides won’t be able to put into the right position.
