Locking Truck While Running Question!

2021, Gas  2500HD Keyless Start

 

My question is.....Is there anyway to lock my truck while it is running with a keyless start and fob? Sometime my dog rides with me and I need to stop and go check my mail at the post office or maybe run in a store for a quick soda. I'm in Texas and it is hot in the summer time, so I would like to to leave the truck running for a few minutes to check my mail or get a soda. is this possible with my setup?

 

Thanks, SSG

I do that all the time for short periods on mine. I just hit the lock when I step out and it works fine.  Not sure how long it would keep running though?

As noted, you should be able to just lock the door while leaving the truck running. From my experience it's about 30 minutes before it shuts off after extended idle. This is with the fob on me and doors locked.

exactly......just lock the truck normally after its running

Thanks guys, I was thinking the fob had to be inside the cab to stay running.

Yup I do this all the time,  you can use one of 3 options.  Lock on fob, lock on inside of door while stepping out, or the quick lock on the handle. As stated truck will only stay on for 30min before shutting off without the fob.

The only way my 20 will lock while running is with fob.  Internal lock and outside lock buttons are inoperable.  Is there a setting for this in the truck settings in stereo screen?

When you start truck, continue to hold start button for about 5 seconds to disable the auto-stop (for running in park). Auto-stop while driving (like at a traffic crossing) will have an actual button to disable. Either option is per each engine start.
