VVDI BE key newest update info 

 VVDI BE key newest update info (VVDI BE KEY PRO)

  1. Fix the bug that W164/W639 EIS data doesn’t synchronize the key.
  2. Fix the bug that the BE key fail to turn on the ignition after repeat try.
  3. Fix the bug of trunk remote open
  4. Fix the bug that the BE key transmitted RF signal for one time, after update, th RF signal can be transmitted 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 auartz crystal, improve infraredcommunication stability.
  8. Boostthe infrared signal when pressing the button.
  9. Support resetting the key frequencybetween 315MHZ and 433.92 in the way of VVDI MB tool or the PCB 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.

Tip: VVDI MB tool has priority over the SMD resistor, which means if you firstly reset the key frequency with VVDI MB tool, the SMD resistor won’t work, and you need to use the VVDI MB tool to erase the frequency then use the SMD resistor.
