Strangest thing happened yesterday. My truck was parked just outside of the mechanical room I was working in and at some point, I decided I better lock the doors in case I'm busy and someone spots my laptop on the console. So I pulled out my OEM ignition key/keyless entry remote and hit the lock button. A few minutes later I came out to the truck to get something and the two front windows were down all the way (and I know they were up before because I had just parked there and it was cold outside) and the doors were locked. The only thing I could think of is that the key was in my pocket and while working I accidentally hit some kind of crazy button combo that caused the truck to roll the windows down. Is this even possible? 2018 F350 SuperCab CC 6.2L XL

 

It happened to me one time on my former 2017 F450. I never could get it to do it again.

 

From the user manual

You can use the remote control to open the windows with the ignition off.
Note: To operate this feature, accessory delay must not be active.

Opening the Windows
You can only open the windows for a short time after you unlock your vehicle with the remote control. After you unlock your vehicle, press and hold the remote control unlock button to open the windows. Release the button once movement starts. Press the lock or unlock button to stop movement.

 

hit lock and then hit it again and hold - if it doesn't work you can turn global down on via forscan. works for open too.

 

You are correct! I just tried this and worked exactly as you described. Pretty cool feature to have, especially on an XL trim, but I'm always hitting buttons accidentally while the remote is in my pocket and I'm working. Is there any way to disable this feature?
