Am I to blame the rain??

Seem to be having a few issues with my lovely Scenic II, I must add not all due to the rain but the couple that may be are.......I have the drivers and one rear window not working and now I can't start the car as the immobiliser wont go off, it just continues to flash. I have mentioned on here before about being able to hear water sloshing about and I have also seen drops in the passenger foot well on one occasion and when I last hovered her the hoover was wet inside too.



I will mention I have recently replaced the battery in my key but its been fine for a couple of days since both keyless and normal too.



Any help on getting it started again please??



Thanks
