Xhorse Mercedes Fobik - VVDI BE Key PCB Board (315 MHz - 433 MHz) for VVDI MB Programmer - Improved Version (Xhorse)

Newest version: 1.5 More compatibility New design High Stability High reliability Supports resetting the key frequency between 315 MHz and 433.92 with VVDI MB tool software or the PCB SMD resistor Default Frequency is 315 MHz Remove the PCB FRE resistor to change it to 433.92 MHz Fits standard Mercedes Key FOB Compatible with VVDI MD Mercedes Key Programmer Compatible with the following:1997 - 2014 Mercedes ALLVVDI BE Key Update Features: 1. Fix the bug that W164/W639 EIS data doesn't synchronize the key2. Fix the bug that the BE key fails to turn on the ignition after repeat try3. Fix the bug of trunk remote open 4. Fix the bug that the BE key only transmitted RF signal for one time after update, the RF signal can be transmitted for two times when press and release the key5. Modify the rolling algorithm, fix some errors of BE key6. Add pre-roll algorithm: the HASH value can roll ahead7. Adopt car-grade quartz crystal, improve infrared communication stability8. Boost the infrared signal when you press the button9. Support resetting the key frequency between 315 MHz and 433.92 in the way of VVDI MB tool or the PCB SMD resistor Tip: 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 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 315 MHz, after removing it will be 433.92 MHz2) Change frequency between 315 MHz and 433 MHz with VVDI MB Tool
