infiniti q50 20 digit pin

[Batts]

I am having issues with the autel. I have replaced ECM and BCM due to water infiltration. When programming keys the online pin writing function fails. I can go into manual mode, I get a 20 digit pre pin and I have to calculate the new pin off of that pre pin number. Does anyone have a 20 digit pre pin calculator and if so, would you be able to calculate it for me?

We had a mobile lock smith come out and he didn't seem to understand what I was asking for. Im just trying to get these customers their car back tomorrow.

Any help is appreciated.
