Sounds like too much to just happen to go all at the same time. I'd check to see if your battery is going. Sometimes irregular power supplies can make the body control module do strange things (lock and unlock doors, forget radio volume control signals, etc). Test the unit and if it's still okay, put it on a charger overnight before you try starting it up again. When I have a vehicle that I leave for a while, I connect a trickle charger like this one:
