That's a good question. My wife's 2008 Escape won't let the car lock with the keys in it, and engine running. My 2000 F-150 allows you to do just what you asked about: start the truck, and lock the door with no problem.
My 2009 F-150 allows the same too. It would be nice if this keypad allowed that feature for cold days and whatnot. Sent from my iPhone using AutoGuide.com App
