FEM all key lost done by CGDI BMW Programmer, working pictures shown as below:
FEM need to be removed to program new key instead of OBD method, Attach 4 pictures showing the location of FEM system, 95128 IC location, 95256 IC location and key learning position.
Here we go one by one
Pic.1: BMW FEM/ BDC installation location.
Pic.2: 95128 IC location
Pic.3: 95256 IC location
Pic.4: key learning position
Good news is: FEM all key lost can be done free by CGDI pro instead of charge extra money to authorize.
Finally, attach two pieces of BMW FEM BDC key programmers made in China:
Xhorse VVDI2 BMW V4.3.0 and Yanhua BMW FEM Key Programmer, both are better quality.
Xhorse VVDI2 BMW V4.3.0
1.support make new key with ignition switch(support add spare key and all key lost, all key lost require ISN)
2.support reset FEM/BDC KM(cluster require reset manually)
3.support erase key(after erase the key position become blank position)
4.support backup coding
5.support restore coding
Xhorse VVDI2 BMW V4.3.0 FEM/BDC system key learn with step-by-step procedure.
Generally there are 3 steps for make keys: get key info->programming FEM/BDC system->make keys
1.backup coding and restore coding can direct operation generally.
2.add keys, reset KM, erase key must programming FEM/BDC system first
3.in FEM/BDC interface, if ‘get key info’ the type not support, it will show: customer should use “BMW E-sys software” program FEM/BDC system. then programming FEM/BDC system with VVDI2-BMW
4.when operation on ‘programming FEM/BDC system’interface,please don’t close this software window until all procedures completed.
5.programming FEM/BDC system, require soldering and get eeprom.(FEM 95128 chip, BDC 95256 chip)usually there are 2 same chips on the module, please refer to the software diagram, select the correct one.
6.programming FEM/BDC system, must restore the original eeprom, restore coding. if cannot restore coding or after restore coding assemble FEM/BDC module back to car, but with problem(such as the remote control cannot start the car
or the car with window problem)please use “BMW E-sys software” coding for FEM/BDC system
7.if connect power to FEM/BDC module, but the relay keep ringing,please contact technical support for help.usually operation on FEM/BDC should be ok,just need to programming.
Yanhua BMW FEM Key Programmer
Picture 2 shows Yanhua BMW FEM/BDC V1.0.5 can program FEM/BDC key and more.
