Had good successs with frequency test ofVVDI BE key proimproved version, frequency between315Mhzand433Mhz, testedwith and without VVDI Mercedes software

This is how to test VVDI BE Key Pro frequencey…

For those have noVVDI MB:

You can change key frequency 315MHZ or433MHZ withremoval of a PCB resistor

Put theVVDI BE Keyto 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 haveVVDI MB TOOL:

You can change key frequency 315MHZ or433MHZ with VVDI MB tool

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

Click on ” Read out key frequency”, the result is315MHZ.

Put the VVDI BE key on the top of the VVDI KEY TOOLand the key frequencyis 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 out433MHZ.93.

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

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