Actually, someone can just hop in and drive the car away if you leave it like that. Once the thief shuts off the engine, however, there's no way to start it up without the key (immobilizer and all that).
Key fobs usually have a VERY short range. You'd have to be standing almost in front of the door's lock button for you to unlock/lock the door. That means no one can sneak up and unlock the doors behind your back as you are walking away. The car can also tell if the key fob is inside or outside the vehicle so you can't turn on the engine even if the key fob is close by but not inside the cabin.
I'd suggest you try to download the owner's manual of the particular vehicle that you're interested in.
