How to Solve OBDSTAR Failed to Read Kadjar 2016 Pin Code?

 Problem:

I need to add a new key to Renault Kadjar 2016 smart card with NCF29A1M transponder by OBDSTAR X300 DP Plus.
Read dflash ok
Make dealer key ok
Add key failed!
Failed to read pin.
Customer card works.
Wondering if following below instructions is safe.
If I will use AKL option and non pin will be correct the customer card will not work. Am I right?

Solution:

Kadjar does not work through the Add key menu, it is done through AKL (all keys lost).

You always have to go through all keys lost and program original key after you read data then you can code original and new key second time.
This is process
Read flash
Save flash
All keys lost
program keys
Then Pre code new key
Program keys
Job done.

Always use battery support for read dflash and keep internet connection stable.
