There are three ways to use Launch X431 IMMO Elite/IMMO Plus to add new keys to Volkswagen 4th Generation IMMO when all keys are lost. All have on-screen instructions to help you operate easily.
Method 1:
OBD Overall Loss Mode: directly read engine data from OBD
Method 2:
All Keys Lost (Dump Mode): disassemble the instrument for direct reading
Method 3:
All Keys Lost Mode 2 (Disassemble and Read the instrument): disassemble the instrument and read EEPROM chip data.
If there is an OBD method, try to read engine data via OBD.
If fails to read data from OBD directly, try AKL dump mode or AKL mode 2.
For example:
Use the third method “All Keys Lost Mode 2” to program VW 4th IMMO with NEC24C64 (2013)
Device used:

After the data is restored, solder the EEPROM chip back to the original position of the instrument, install the instrument and click “OK” to proceed to the next step
The instrument panel has entered a black screen state which is a normal phenomenon. Please be patient and wait.
Reading anti-theft data, confirm to save the data with a new filename
After obtaining the anti-theft data, the instrument panel will enter a black screen state again, which is a normal phenomenon.
At the same time the anti-theft data will be read again.
Confirm the anti-theft information of the vehicle
Take a screenshot to save the info
Insert the key or place the key near the key sensing area, and turn on the ignition switch to illuminate the instrument

Input the number of keys to be learned
Select “VW”
Follow the on-screen prompt to insert the key to be learned successively within 30 seconds and turn to “ON” position
Interval for changing key is less than 5 seconds for smart key. Place the key to be learned near the key sensing area, and press START button.
