How to solve Tango Nissan Qashqai “Add Key Not Tested” Error

I read Nissan Qashqai J10 BCM 284b2 jd 12a by Orange5. There was only one option under Immo Mazda2 09- to read this MCU9s12xdt384(1L15Y). Read fine, Tango Key Programmer can show keys and login but I can’t write new key. When I add .bin file information appear “Add key not tested” When I write key or transponder pcf7936 info display “invalid crypto key” and it change chip page 3 from 06 to 0E making it crypto mode. Car has proximity twist on ignition/ key I tried original dealer key also blank pcf7936 and preceded for xtrail qashqai.
I tested also two random eeprom from DK file 4KB the same situation but one file 2kb write the key with no problem.
My question is did someone face this problem? where is the problem? can I use 2kb eeprom file with key from different car and write to my module with original flash?

Suggestion:

Try with another Key Programming Tool? Tango is not the only one.

Xhorse VVDI2 EEPROM recognized and recorded it.
