Ford Territory 2013 SX immobilised issue

[almast]

I have changed my dashboard for ford territory 2013 . After changing i am facing issue of car immobilised. Tried recharging battery and changing battery. Not solved. Car does start for a second and turn off again and error shows on screen saying “vehicle immobilised” . Tried spare keys. Keys battery is fairly new as changed few weeks ago. With this also shows error of Air bag and RSS sensor.

Do i need to reprogram the keys?
Or do i need reprogramming of car?

Anyone please help.thanks
