2019 F450 looking for a key on power under the hood. Odd one

I first used the fuse for the rear seat heat. Can't imagine that one being hot while the truck is off. I then checked a bunch more and they were all hot. Hood is open so in the morning I will check again and see if they are all hot or not.

Its just my old school brain that is having issues. Never met a vehicle with a fuse box that was hot when the power key was off. Its a push button, but the key is in my pocket. Maybe I should leave it far from the truck.
