My shutters close when I auto start from the key fob. They close for 3 seconds then open back up. Never seen them stay closed though. Of course I can’t look at them when driving either so there’s that.

Even if the shutters were closed, they are plastic, at least in Gen2, and can be easily broken...

On my Gen 2 they would close on startup then open again. I noticed them partially closed once when I got home after a drive in the snow so I assume they open and close based on either ambient temperature or engine temperature. I have never seen them closed when it's above 65-70 degrees outside though.

On my old f350 I simply disengaged the linkage from the key cylinder on all of the doors to prevent someone from opening the door with a screw driver or similar.
