locking doors when engine running
The problem with some of these solutions is that there is a feature that if the keys are in the ignition the door will unlock after a bit. Now if you have the door combo thing, that works like the others have said.
Usually what I do on my 08 is I have my key and fob on 2 separate rings. So I go in start truck and detach fob and walk out shut door and lock with fob
