Looking at a Gmc Yukon XL with 5.3 engine. Will engine keep running while locking the doors. We have a dog and sometimes leave him in truck with air on. When we go to a place to pickup things. Will truck still run with doors lock and key running in ignition ? Or will it only run so long before it shutoff ?

My 16 runs while I go into the store for snacks. It’s only 5 minutes or so.

No time limit unless you use remote start, then it's 10 minutes. This can be modified but is involved and pricey.

^ There is a way to extend this to 20 minutes but I don't remember the button you push. Should be in the owners manual.

It will but it also makes it super easy for a smash and grab. All someone needs to do is use a popper on the glass and they’re off with your truck. And since the keys are in it most police won’t even treat it as a stolen vehicle.

Keys are in it only if not push button.
