Improvements to VVDI BE Key Pro:
Resolved the issue where W164/W639 EIS data did not synchronize with the key.
Fixed the problem where the BE key would stop functioning after repeatedly turning on the ignition without removing the key from the EIS/EZS. This issue often occurred during diagnostic work, such as switching the ignition off and on to clear faults, resulting in the car not starting.
Addressed the bug related to trunk remote opening, particularly on vehicles equipped with power lifts on the trunk door.
Rectified the problem where the BE key only transmitted an RF signal once. After the update, the RF signal can now be sent twice when the key is pressed and released.
Modified the rolling algorithm to fix certain errors associated with the BE key.
Introduced a pre-roll algorithm, allowing the HASH value to roll ahead.
Implemented a car-grade quartz crystal to enhance the stability of infrared communication.
Amplified the infrared signal when the button is pressed.
Added support for resetting the key frequency between 315MHZ and 433.92MHZ, which can be done using either the VVDI MB tool or the PCB SMD resistor.
Note: The VVDI MB tool takes precedence over the SMD resistor. If you initially reset the key frequency using the VVDI MB tool, the SMD resistor method will not work. In such cases, you will need to employ the VVDI MB tool to erase the frequency before using the SMD resistor.
Procedure for resetting the frequency using the PCB SMD resistor:
Solder a 1K SMD resistor to the indicated position, as shown by the arrow. This sets the frequency to 315MHZ, and upon removal, it will be adjusted to 433.92MHZ.
