What do you trying to do ?

I have lost all keys, so trying to make dealer key.
Now i have made new key with dump from bcm. Read out 95320, programmed it as it should with Tango, write back file to bcm.
Put back Bcm in car, and it starts and running fine. Stops car and now it wont start anymore... immo active...

Now I dont know what is going on, anyone got any ideas I would be thankfull.
Should say i programmed it as key number 3, but cant se why that could be any explonation..

Little update. made new dump and new key today. Test on car, ignition on and starts on first try. Stop the car and took key out of ignition, after that no ignition on dash, same error, immobilizer active...
What can make this trouble?? Anyone??

Could be, but cant understand that as it comes from master... but is pin and cs from post ok?

Hello !
Its 100% OK .

Yes I belive pin and cs is okey, can also login with pin on BCM.
The strange thing is that I can write back file made by Tango to BCM, car starts first time everything is okey. Stops it and take out key, no start due to immobilizer active. I then can write back file again to bcm and start again, but only first time.
Dont understand anything anymore....

I little update. After some good help I used tango to make crypto and write CS to new key AS dealer key, and Vcds after to program new key to car. Works, and car starting😊
So thanks for every reply and help😊
