Users can refer to following information (3 steps for make keys:get key info->programming FEM/BDC system->make keys)
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

Notes:
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.
