"Xhorse VVDI BE Key Pro Features:
VVDI BE keyPro improvements:
1. Fix the bug that W164/W639 EIS data doesn't synchronize the key.
2. Fix the bug/fault that the BE key stop work after repeatedly turn ON the ignition without remove key out from EIS/EZS for example with work on diagnostic...switch IGN OFF---ON for erase faults...then car not start
3. Fix the bug/fault of trunk remote open on cars where power lifts on trunk door mainly...

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"
