Here, 5 steps for you to use Yanhua BMW FEM/BDC programmer to add/program a new FEM system key by OBD.
Step 1: Backup (read) coding data
Step 2: Update/program ECU
Step 3: Add key
Step 4: Recover (write) coding data
Step 5: Delete(disable) key
Yanhua BMW FEM Key Programmer adds a BMW 1 series 2014 FEM key

Step 1: Backup (read) coding data
Cut off the power supply
Disassemble FEM
Take photos before you disassemble the FEM for correct fuse location
Take apart the IC chip to read and save data
Desolder the IC chip on the programmer board
Read EEPROM chip data with universal programmer, e.g Yanhua CKM100. Run CKM100 car key master software Yanhua Auto Master Series to read data
Go to Specialized programmer, then IC chip: 95128
Read and save original 95128 EEPROM data to BIN format
Then back to YH BMW FEM programmer software
Disconnect the battery and remove FEM/BDC, read 95128/95256 EEPROM data with universal programmer and save it
The software prompts to write the newly generated EEPROM data back to EEPROM chip, solder the EEPROM back to FEM/BDC.
Install the FEM/BDC back to vehicle. Recover normal power supply for vehicle and turn on ignition switch.
In Yanhua Auto Master Series, restore/back data
Write data successfully
Then desolder the IC chip to the FEM EEPROM
Then install the FEM to the car
Step 2: Update/program ECU
Software prompts to upgrade ECU. Please ensure the vehicle voltage no less than 13.0V.
The software prompt that upgrading ECU. It will take 15-30 minutes. The software began to count down.
Step 3: program/learn (add) key
Restore the original data with CKM100 car key master software
Please recover the first reading original EEPROM data by programmer. And install the FEM/BDC and restore normal power supply for vehicle.
The working key is close to the emergency starting induction antenna (located on the lower right of the steering wheel)
The software reads and displays the relevant information about the working key.
Software pop-up key list, the user can choose key which need to be added. Learn the key number and click “Learn new key” (Recommend to use the key number sequentially and in turn)
Learn a new key
Put he new key here for key learning
Exit
Step 4: Recover (write) coding data
Write coding data successfully
Successfully programmed a new key
Step 5: Delete (disable) key
DO NOT delete the working key
Deleted keys disabled
Success!! Yanhua BMW FEM/BDC key programmer programmed a new key.
