2011 LC. I heard the low beep/hum of the alarm horn coming from the engine and noticed my key fob not working. Cant start the car, none of the electronics work. Cant even adjust the seat. if I open the door with the key the horn stops for a few seconds. If i hit the brake pedal it stops for a few seconds. Then it just keeps going and never stops. Got the car washed yesterday and noticed there was some water coming in (havent cleaned my sunroof drains Im sure thats it) but i cant move the passenger seat to get to see any fuses. It was moved completely forward to make room for something in the back before all this happened. Any ideas of things to check/ do? At a loss here. Thanks!!!
 
Whenever I see these issues, I immediately think of corrosion from water ingress in the large square connectors behind the DS and PS kick panels. Have you checked those?

Follow this video and check both DS and PS connectors

 
The battery is also dead as a result of water in those junctions causing a short.
 
Great thread here for a fix
