Read before VVDI BE Key Frequency Change

  • by

There are 2 ways to change frequency on xhorse mercedes regular key.
Software setup via vvdi mb tool and resistor removal.
Link to get details:


VVDI MB tool has priority over the SMD resistor on VVDI BE key board, 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.

The way to reset the frequency 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.
