No central locking, no immobiliser light, no start

[Vitor Alves]

Hello, i checked the condition of the two plugs in the uch by unplugging and plugging them, next to the relays, and now i got no central locking, immobiliser light is always off, and the car wont start? I accidentally forgot to unplug the battery before doing this. The rest of the electronics seem to be working

Is my uch shot, or is it only some anti-theft mechanism?
