Select the NEC chip data for the instrument
When selecting the chip data, pay attention to the backup date, time and chip model
Confirm whether the meter needs to load the external EEPROM 95320/ 95128 data
Click “Yes” to load the EEPROM data
Calculate IMMO data and keep the network smooth during the process
Save the IMMO data after calculation
Check if the IMMO data is normal

Step 3: Make dealer key
Click “Help” beside [Duplicate the key] option
Connect Mini ACDP-2 to the PCF-KEY Adapter properly
Then click Duplicate the key
Note:
The new key should be a blank key that ID can be changed, and the blank key has been changed to the ID of the lost key.
Place the blank key that has been changed to the original car’s lost key ID on the PCF-KEY adapter correctly.
Confirm the key info
Select the IMMO data saved in step 2
Select car manufacturer- VW
Start programming the key data
Make dealer key successfully
Step 4: OBD learn key
Confirm the vehicle system info, and select IMMO data
Enter the number of learning keys
Don’t turn off the ignition during learning!
If the other keys are too close to the induction coil may cause the learning failure.
Put the first key close to or insert into the induction coil and continue
