Yes you can, works fine, I do it all the time, I hate to shut the truck down, just for a quick trip into store, etc. You will have to lock the doors via the remote though, mine won't let you lock 'em with the door switch, when the door is open, not sure what year that was started in, but it is a nice feature. It also won't let me lock the doors if the lights are on.
