2016 F250 4x4 Diesel Super Duty will not key or remote start?

What is your question?

This has been occurring for the past month or two. Does not start with using my key (I don't have a button). Now that it has gotten cold (32 this am) it will not remote start either. I plugged in to outside outlet and waited at least 30 minutes to see if it would even work. Nothing. I have checked the wires to the batteries and also have made sure nothing was loose. Truck only has 65K and I keep up with all the maintenance. Maybe there is something else I could do to solve this without going to dealership. Thanks! Any suggestions would be great!
