Pleased to share my purchase experience of VVDI PROG Auto Key Programmer. Just got this programmer for a few days from China.(I am Chinese, also)
Package came to London for about 6 days, for €385.
Ps. VVDI PROG 3.40 free download I found:
(software, driver, IMG&Language files...)
And I used this vvdi prog and vvdi2 to do BMW all key lost. Here is the procedure. This vvdi2 is from my friend, sounds from China also.
Step 1: Read CAS4+ 5M48H EEPROM with VVDI PRO
Disassemble the CAS4+ and ECU.
First, read CAS4+ EEPROM data.
Take out the circuit board from CAS4+.
Follow VVDI Pro wiring diagram to connect the cables with circuit board.
Remove 4 components on CAS4 (solder them when finish operation ) and begin wiring connectors
The circuit board after removing 4 components.
Start wiring connection according the wiring diagram..
Then begin to read and write.
Select “BMW CAS4-5M48H” EEPROM
Click “New” and then click “Read”.
Now the equipment is being initialized.
Check the chip type.
Select “Yes” to crack chip.
Cracking the chip...
OK, finish cracking.
Start reading the data.
Finish reading data.
Name the file.
And click “Save”.
Step 2: Read BMW ECU
Disassemble the ECU. Punch a hole here for wire connection.
Follow VVDI 2 wiring diagram to connect the cables with ECU.
Point the boot. Point contact and press it for a while.
Go to the software and select EEPROM.
Click “New”.
Click “Read”.
Well, begin checking this equipment. Device initializing.
Crack the chip.
Click “Yes” to continue.
Finish reading data. ISN is also displayed.
Save data.

And click “Save”.
Finish data reading.
Step 3: Write key with VVDI 2
Begin to write the key.
(All the data have been read out, so we can begin writing the key.)
Insert the key in VVDI2.
Open VVDI2 software, Quick Start.
Select BMW.
Select “File Make Key”.
Select “5M48H”.
Click “OK”.
Load the data, select the folder “000000000”.
First load BMW CAS4+ data. Click to open.
Select “Key3” and click “Generate Dealer Key”
Click “I have the engine data, click Next to load it”, and click “Next”.
Load the ECU data, “baoma 525ecu.bin”, and click “Open”.
You will prompt that it will take 30 seconds. Click “OK”.
It is generating a key. Wait! Write key success.
Step 4: Test new key
OK, finish writing the key. And now, we go to check it. (click “OK”)
Check if the key can work normally.
Put the key on BMW test platform.
Pay attention to the green light (LED 3).
The green light is lighted, which means the key can work normally.
Then take the key down.
You will see the green light will be off.
Again put the key on BMW test platform.
Key matching is successful.
