Lonsdor K518ISE program new Renault keys (All keys lost)

Programmeur De Clef

Renault key programming manual (using Lonsdor K518ISE)

Purpose: Program new keys to Renault cars (when all keys are lost)

You need:

tools to disassemble the anti-theft/immo box

VVDI-Prog to read EEPROM data

Lonsdor K518ISE to program keys


1you can directly program a new key to pre-2010 Koleos;

For post-2011 Renault models, you need disassemble the anti-theft box to first read the backup EEPROM data, then program keys (when all keys are lost)

2« Anti-theft system 2″: generally only for Koleos.

if it fails, go to « anti-theft system 1″for cars before the 2010 year (password advice:first select Group 4)

« Anti-theft system 1 »: for other Renault models

Incorrect password:

If the password is wrong, please turn on the ignition and wait for 1 minute or so to try another group of password again. The error message is « login failed » or « system does not support login operation ».

Megane password advice:first select Group 2;

4 Load.bin file into Lonsdor K518ISE:

use the USB cable to connect the K518ISEand the computer, find out and open internal memory of the K518ISE device , put the.bin file in the the folder « customfile » .

NOTE: .the bin file suffix « bin » must be lowercase;

the file directly into the folder (DO NOT create a new folder)

How to do:

Part 1: match the smart card

1 press the start button, open the driver door;

2 the system tries to get the password

if the model can be read out, please select the password. If the vehicle password cannot be recognized, please read EEPROMdata and put it into Lonsdor K518ISE. Then do as follows:

① with the USB cable to connect Lonsdor K518ISE programmer to the computer, the computer will display K518 host internal storage;

② copy the .bin (lowercase) file of CPU data to the Lonsdor K518ISEhost’s customfile directory;

③ return to the smart card match operation, select the import file for secret read.

3 insert the smart key need to match . the first key match is completed; please follow the pop-up to continue to match another keys;

4 remove the smart key if you do not continue to match keys

Renault key programming is complete.

Step 2:VVDI Prog read EEPROM data

Open VVDI-Prog software

Select Renault-BCM-XDT384


Follow vvdi programmer wiring diagram to connect

lonsdor-k518-koleos-11 lonsdor-k518-koleos-12

Read eeprom data and save data to bin format

lonsdor-k518-koleos-13 lonsdor-k518-koleos-14

Connect K518 host with laptop via USB cable

You will see “customfile” folder on K518 software

Copy the eeprom bin file to “customfile” folder


Step 3: Lonsdor K518 program Smart Key

Re-install BCM from car

Connect Lonsdor K518 key programmer with vehicle via diagnostic socket

Select Renault->By System->Smart Key->Immobilizer system 2->Program smart key

Press on the Start button, press YES to continue


Open the door on driver side


Lonsdor K518ISE shows unable to identify pin code automatically.

Follow guides below: (We have done 1 and 2)

1.Connect K518 host with laptop via USB cable. You’ll see “customfile” folder

  1. Copy eeprom bin file to  “customfile” folder
  2. select eeprom bin file on  “customfile” folder


Select Renault BCM data.bin


Insert a new smart key to be programmed into the card slot

lonsdor-k518-koleos-25 lonsdor-k518-koleos-26

Configuring system

Program success. Press YES to program next key


Insert next smart key into card slot

Program success.

Remove smart key


Key learning success


Part 2: start the collision recovery

If there is a car crash, the system will automatically start the protection program. and after repair, you need to first release the protection to start the vehicle.

Connect the Lonsdor K518ISE device, and the system communication clear fault information.Complete.
