The criminal element is nothing if not creative, and what they've been doing is casing people's homes to see if the occupants do what so many people do: keep their keys on a plainly visible, easily accessible rack in the kitchen. A peek through the back door is all it takes, and a quick B&E lets the thief snatch the car keys and drive away calmly and quietly -- immobilizer be damned. If you don't have a garage in which to store your car, you might want to make a point of keeping the keys tucked well out of sight. Sure, it may be common sense, but we all let our guard down at home. What's easy for you is, unfortunately, also easy for some dirtbag with eyes for your machine. No sense making his or her life any easier.
