This is my working desk, you can see one 8-Foot Chip Adapter is plugged to CGDI BMW which is plugged to a computer, also CGDI BMW is connected to a BMW FEM /BDC test Platform which is connected to FEM /BDC immobilizer module. 

Generally speaking, I need:

One 8-Foot Chip Adapter

One CGDI BMW

One BMW FEM /BDC test Platform (used to test if FEM/BDC immobilizer system is good or bad)


One blank key



Since this tool is easy to use, what you need to do is read the on-screen message and follow it to do. so I didn't take many photos here, but only two ones here.



Image 1: all are fine.




Image 2: Read out password, ISN, Key Sync Code, DME ISN.
