Tried to read data for 400 times and all success without data loss. So YH BMW FEM key programmer read data 100% safe and fast.
Top 2: Xhorse vvdi2 BMW V4.3.0
Xhorse vvdi2 BMW V4.3.0 can program key on FEM/BDC system incl. add key and program new key with all key lost (need ISN)
===== 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
BMW FEM BDC system functions authorization for extra fee:
1) Have VVDI2 with BMW OBD Function + Condor Mini cutting machine, the FEM BDC authorization cost 600USD
2) Have VVDI2 with BMW OBD Function, but has no Condor Mini cutting machine, the FEM BDC authorization cost 800USD
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.
How to use VVDI2 4.3.0 to program key on FEM/BDC?
read FEM/BDC coding via OBDII or on the bench
you’d better not close this window after starting this procedure
open FEM/BDC shell, find out where the 95128/95256 chip is, read EEPROM dump via BDM programmer
load original EEPROM dump and save special EEPROM dump, write special EEPROM dump back to the 95128/95256 chip
Restore FEM/BDC shell, provide -12v and connect it via OBD
this operation requires connecting FEM/BDC on the bench, and make sure you finish step 1 ans step 2
provide +12v to FEM.BDC and connect it via OBD
open FEM/BDC shell, write original EEPROM dump (read step 2) back to the 95128/95256 chip
restore FEM/BDC shell and connect it via OBD
loading coding file (read step 1), write to FEM/BDC via OBDII, finish FEM/BDC programming

Top 3: BMW explorer program key for BMW FEM /BDC
BMW-Explorer since version 14.05.08 allows users to program ignition key for FEM / BDC
Key programming into FEM / BDC is divided into several stages
1 Preparation of FEM / BDC thru OBD
2 Preparation of FEM / BDC using programmer (Reading BACKUP)
3 Programming FEM / BDC with BMW-Explorer via OBD
4 Write back BACKUP with the programmer
5 Key programming thru OBD
It is necessary to perform a quick test , go to the FEM / BDC and click the “Key learning” button,
The program will check for a supported version of the unit, prepare the unit for the next procedure, and will display the message “Read Eeprom and upload in calc”.
Remove the FEM / BDC unit as described HERE. Disassemble the FEM / BDC unit as described in THIS SECTION.
Read 95128/95256 Eeprom (pictured in the upper right corner) using programmer
(Orange Xprog or others that supports Eeprom 95128/95256).
Download Eeprom into BMW-Explorer, and save EEprom and write it back into the FEM / BDC.
Install the unit on the car in the reverse order of removal, and connect BMW-Explorer via OBD.
The car probably will not respond to the key, do not get scared!
Connect to FEM, press “Write keys”, Explorer will propose to program the FEM / BDC, agree and wait for the programming to finish.
After successful programming, the program will write to you “Return the saved original Eeprom”, then remove FEM again and using programmer, return the previously read contents of EEprom 95128/95256. Then you can install the unit back to the car.
Sometimes it is possible that after the last manipulation the FEM / BDC will stop responding to the diagnostics, then you need to flash this EEprom into the unit and program the unit with Esys or ISTA-P and start the unit preparation from step 1.
P.S: Follow the instructions and save your time.
Connect to the FEM / BDC control unit using the BMW-explorer, press “Extra options” then “Key learning”. Key programming window will open and will read the key data we need for programming.
If you have a working key, then you need to bring it to the emergency coil as pictured below and press the “Read crypto key” button.
About successful reading of the “Crypto” BMW-Explorer show “Crypto Ok” message.
If you do not have a working key, then you need to read the ISN from the DME and enter it into the “ISN from DME” window.
You can also enter 8 bytes of the “crypto” manually.
Now you can start to learn keys. To do this we must select a free track for the key and press “Learn key”, bring a new key to the emergency coil on the steering column.
