	Improvements: 
	  
	1. Fix the bug that W164/W639 EIS data does not 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... 
	  
	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 433.92MHz in the way of VVDI MB Tool or the PCB SMD resistor 
	  
	Important Notice: 
	  
	1. VVDI MB Tool has priority over the SMD resistor, which means if you reset the key frequency with VVDI MB Tool firstly, then SMD resistor will not work, and you need to use the VVDI MB Tool to erase the frequency then use the SMD resistor. 
	  
	2. The way to reset the frequency with the PCB SMD resistor: 
	  
	Weld a 1K SMD resistor on the arrow pointed position and the frequency will be 315MHz, and frequency will be 433.92MHz after remove the SMD resistor.   .jpg) |
