Xhorse VVDI BE Key Pro Improved Version and Smart Key Shell 3 Button for Benz

Xhorse VVDI BE Key Pro Improved Version with Smart Key Shell 3 Button for Benz

VVDI MB BE Key Yellow Board vs Green Board
The yellow board does not contain 200 bonus points, but cheaper than the green board.
Work the same, only colour difference.
Green board include 200 bonus poinst=1 MB tokne

Xhorse BE smart key:
Super Stable
Frequency changeable 315Mhz/433MHz
Reusable - you can reset it
Programmed by all kinds of MB key programmer, such as Autel IM608, CGDI and VVDI MB, Key Tool Plus, Digimaster-III ,CKM100, AK500, MBE MB-KEY OBD2, NEC-57 MB-PRO and so on
Can use MB smart key and it worked lock/unlock/ trunk.
Xhorse brand, superior quality.
Applicable chip models:705 Moto(1997-2000) NEC(2001-2005) NEC(2006-2010) BGA(after 2011)

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.

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.
