My house was broken into in 1997, and the goobers tossed a rock through the door window and unlocked the deadbolt, to gain entry. I installed double-key deadbolts, and leave keys in them at all times when we're home, but remove and hide the keys when we leave the house. This way, the slimebags have to hustle all the stolen goods through a window, if they cannot leave through the door. Slows them down and makes it a lot more obvious. The use of double-key deadbolts does require that you incur more risk of, shall we say, an egress failure in an emergency. I also replaced my glass-fronted door with a fanlight window style that cannot be reached-through, if broken.
