Lonsdor K518S/K518ISE key programmer (e.g. Lonsdor K518 Pro (CN), support the same function)
Lonsdor LKE Smart Key Emulator 5 in 1
Lonsdor Super ADP 8A/4A Adapter (incl.ADP-25 adapter+ 27P harness+ 24P harness)

  • Disconnect the interface between the smart box and the car, then connect smart box and ADP adapter via the professional harness
  • Connect ADP adapter to the OBD port of vehicle
  • Make sure K518 key programmer WiFi connection is good


1. Backup IMMO data
Enter the backup IMMO data menu, and make sure all device connections and networks are good.
Read the software number
Input a file name to save the data

Note: remember the file name, and it will be used in key adding and deleting.

2. Generate emulator key AKL (8A/4A)
Make sure the network connection is normal
Select the file has just been saved


Plug the antenna adapter into K518 Pro (Chinese version)

Note: For K518, you should plug the Lonsdor LKE emulator key into the host port of the K518. (Antenna adapter has the same function as LKE emulator)


Wait a moment to generate key
Emulator key is generated successfully, then use the emulator key to turn on ignition switch and enter the key matching function to add new key
Use the top of the emulator key to press the start button twice
Start the car successfully


3. Add smart key
Make sure the network connection is normal and the original smart box has connected to the vehicle
Use a registered original key or emulator key to add new key
Turn the ignition switch on
Read out the software number
Turn off the ignition switch, and open the dual flashing lights
Select 'Load the smart box DFlash file to get 12-digit PIN code'


Select the file that has been backed up
Detect out the registered key number is 2, and the key can be registered is 5.


Finish the following operation within 30s
  • Put the back of the registered key or generated emulator key on the Start button, when the buzzer beeps one time, remove the smart key or emulator key
  • Put the back of the smart key that needs registration on the Start button, when the buzzer beeps twice, remove the smart key


Match successfully
The registered key number is 3, and the key can be registered as 4.


Directly use your finger to turn on the ignition switch (the smart key has just been registered, so doesn't need the emulator key)

Then press the programmed and registered smart key on the Start button, the buzzer beeps.

Programming is completed
Finally, turn off the ignition switch and dual flashing lights
Check if the programmed key can work normally or not

4. Delete smart key

Turn the ignition switch on
Read out the software number
Turn off the ignition switch, and turn on the dual flashing lights
Select 'Load the smart box DFlash file to get 12-digit PIN code'
Select the data that has backed up
Put the key to be kept near the start button, beeps one time


Remove the keys that need to be deleted from the car
