DEW attack in Canneto di Caronia?

[ArMaP]

[*]Remote for ceiling fans malfunctions. Fan speed now turns on the light and light cant be shut off. Used to work fine. 
[*]Car doors lock unlock and lock while inside garage. We arent butt dialing on key fob. 

Are those remote controls radio or infrared? Interferences on infrared remote controls would be even stranger.

Edited to add that, regarding problems with electric appliances, we had that problem on the building I live in a few years ago, the most noticeable were the LED lamps getting fried after just a few months.
I decided to connect an oscilloscope to one socket during a time the lights were flicking and I could see that there was some kind of interference, as if it was another erratic voltage added to the normal 230V AC.
The problem was found to be a bad connection in one of the cables connecting the general electric grid to our building, a new connection solved the problem.

This does not mean your problem has the same cause, it just means that sometimes things are simpler than we think.

PS: if you could get an oscilloscope it would be great.
