1 How to use Lonsdor K518ISE to program BMW FEM BDC key?

 

Three steps: read key info–>pre-process FEM/BDC system–>make a dealer key

In details…

 

Step 1: read key info

MUST read key information first

 

Step 2: pre-process FEM/BDC system

MUST DISCONNECT THE BATTERY

 

1: OBD back up original coding data:

On the car or test platform, connect to FEM/BDC system, then back up original back up coding files via OBD

2: read out EEPROM backup data & generate a service-mode EEPROM:

-> Disassemble FEM/BDC module, find out chip 95128 or 95256, read EEPROM data using a ECU programming tool: VVDI-Prog, Orange5 and the like;

-> Copy the EEPROM data into to the Lonsdor K518ISE customfile folder;

-> Run the program, read original EEPROM data and generate a service-mode EEPROM, upload data of the service-mode EEPROM, write it into chip 95128 or 95256 with help of a ECU programmer

-> Restore FEM/BDC system, supply battery to the car and connect via OBD

3: programming

-> This step need to be done on the BMW FEM/BDC test platform;

-> Make sure that Step 1 & 2 is finished

-> Connect FEM/BDC system to power supply and connect to the OBD port

 

4: restore EEPROM data

-> disassemble FEM/BDC module, write original EEPROM data (Step 2) into chip 95128/95256

-> restore FEM/BDC system, connect to OBD

 

5: restore coding data

-> load the backup coding files (Step 1), restore coding information via OBD

 

6: pre-processing is complete.

 

Step 3: make a dealer key

 

1: Lonsdor K518ISE read out data, select the will-be key position

2: a “used”key to make a dealer key

All keys lost: enter 32bit ISN codes to make a dealer key

3: put the key near the car immo induction loop

4: detect the original key, read out immo data

5: put a new key near the car immo induction loop

6: detect the key key, key learn (don’t move the key, keep stable)

7: key learn is complete

 

Step 4: disable the key

 

1: Lonsdor K518ISE read out data, select the key ID position to disable

2: put a “used” key near the car induction loop

3: K518ISE system tries to connect to CAS, disable the key with current ID position, disable key successfully

 

Step 5: enable the key

 

1: Lonsdor K518ISE read out data, select the key ID position to enable

2: put a “used” key near the car induction loop

3: K518ISE system tries to connect to CAS, enable the key with current ID position, enable key successfully

 

Step 6: delete the key

 

1: K518ISE read out data, select the key ID position to delete

2: read FEM/BDC key password

3: delete the key successfully; the key position is blank

 

THE MOST IMPOERTAN TIPS

1: You must read key info before everything you’ll do

2: to pre-process FEM/BDC, you should pay attention to:

– backup coding codes to continue

– disconnect to the power supply/battery, have a ECU programmer to read EEPROM data, up load data in K518 customfile folder, read new EEPROM data loaded just now, generate service-mode EEPROM data, read service-mode EEPROM data, write data into the chip, install CPU on the car

– ECU programming: need 6 min, with power supply connected

– disconnect to the power supply, disassemble CPU, write the original EEPROM data into the chip, install CPU on the car, connect to the power supply, make sure communicate is successful

– upload coding files (Step 1), restore original coding info to pre-process, then make a dealer key

3: 32bit ISN codes is required to program a new key when ALL KEYS ARE LOST

 

Note: If you want to program BMW FEM key when all keys lost, you are required to enter 32-digit ISN code.

2 How to use CGDI Prog BMW to OBD program FEM key

 

Go to BMW OBD Key Match

CGDI-BMW-FEM-program (1)

The current FEM/BDC needs to update the ECU program before performing key matching. Please ensure that the car battery has enough power, the programming process, please keep the equipment cable connection

CGDI-BMW-FEM-program (2)

Please remove the FEM/BDC and then use the CGDI Prog programmer to read and save data from the P5XXX EEPROM chip on the FEM/BDC computer board, then click on Next

CGDI-BMW-FEM-program (3)

Read the original car EEPROM data file

CGDI-BMW-FEM-program (4)

CGDI-BMW-FEM-program (5)

CGDI-BMW-FEM-program (6)

Use the CGDI Prog BMW to write the calculated new data to the 95XXX EEPROM chip, then put the FEM/BDC back into the car, thn click on Next

CGDI-BMW-FEM-program (7)

Car battery voltage: 11.93V

Prepare the programming ECU

Security authentication is in process

Safety certification through

The ECU is being programmed

CGDI-BMW-FEM-program (8)

Please remove the FEM/BDC and then use the CGDI Prog programmer to read and save data from the P5XXX EEPROM chip on the FEM/BDC computer board, then click on Next

BMW FEM/BDC Coding/Programming with VVDI2 full kit 4.3.0 above

vvdi2-bmw-fem-programming-2

step 1:

  1. read FEM/BDC coding via OBDII or on the bench
  2. you’d better not close this window after starting this procedure

 

step 2:

  1. open FEM/BDC shell, find out where the 95128/95256 chip is, read EEPROM dump via BDM programmer
  2. load original EEPROM dump and save special EEPROM dump, write special EEPROM dump back to the 95128/95256 chip
  3. restore FEM/BDC shell, provide -12v and connect it via OBD

 

step 3:

  1. this operation requires connecting FEM/BDC on the bench, and make sure you finish step 1 ans step 2
  2. provide +12v to FEM.BDC and connect it via OBD

 

step 4:

  1. open FEM/BDC shell, write original EEPROM dump (read step 2) back to the 95128/95256 chip
  2. restore FEM/BDC shell and connect it via OBD

 

step 5:

loading coding file (read step 1), write to FEM/BDC via OBDII, finish FEM/BDC programming

 

 

Attention please!!!

– You can directly backup/restore coding

– You have to pre-setup the FEM/BDC module before deleting/adding keys or resetting keys

– You’ll be told other tools need to be used first to program the FEM/BDC system, then setup FEM/BDC via VVDI2. It happens when you do FEM/BDC key learning, and you don’t have a working software version

– You’d better not close the VVDI2 interface when you pre-setup FEM/BDC

– You need do with 95128(FEM) or 95256(BDC) chip when pre-setup FEM/BDC

Note: there are two 8-pin chips; do not disassemble the wrong chip; better refer to the wiring diagram

– You must restore original EEPROM data, restore coding when pre-setup FEM/BDC. If you fail to restore coding or the remote cannot start or something wrong with the window (or other failures probably) after coding restore and FEM/BDC installation, please use other tools to do re-coding FEM/BDC

– Ask tech support @obdii365 for help, if the replay sounds continuously after supplying power to the FEM/BDC. Usually, it needs programming.
