Flood under drivers seat

[p3230]

I had a flood under the drivers seat a while back from blocked drains, I fixed the blockage took out the immobilizer under the seat sent it out for repairs dried out the interior reinstalled everything now my fob doesn't work, no lights when I open the doors, rear defogger doesn't work and the door lock in dash doesn't work also the flashing light on the dash doesn't work, trunk front and back only work when the key is in the on position, but the car starts. Do I have to get my immobilizer reprogrammed, or is there something else that I have to do. 2003 Boxster S.
