Jaguar XF 2013 BCM key adding and repair script

[+tomanycars]

Is there a script that can help with the jaguar xf bcm. ? 

 

They get scrambled when the battery is disconnected. Or is run flat from time to time. , there is a procedure to try and bring it back to life which I have but it's not clear cut and it doesn't always work. , i was hoping there maybe one which speeds up the process and allows further functionality.
