Ok so this allows them to unlock the car, maybe start it, though the article doesn't really get into that, but then what? After they drive beyond the range of the amplified key transceiver?

they won't be able to start it again, but once they get far away, they don't really care as the car is now gone

I imagine for safety reasons the car won't shut off just because it's out of range. If it did it'd certainly solve this problem. In any case, they'd just drive it to the chop shop.

  I can confirm that it doesn't shut off. At least in my case, it beeps for a while saying "KEY NOT DETECTED", but it doesn't seem to actually do anything about it. When my key battery was low this would occasionally happen and it wouldn't actually do anything until you need to actually start the car again after stopping it.

09 Avalon uses same principle as in the article and is most likely vulnerable. Functionality that I have encountered: Battery charged in fob: Walk up to car push any button located on handle of doors to lock vehicle or push button on trunk to open trunk. Within proximity to any door lights under side view mirror light up, interior lights also turn on. After touching driver handle driver door opens, any other door handle touched (within proximity to fob) will cause all doors to open. Battery dead: Trunk will open if fob is held directly near button. Similar behavior on doors fob must almost be in hand pushing button. Valet key can open the driver door. Buttons to unlock etc dont work. Have to hold fob near push to start to start vehicle. Depending on proximity during drive the alert on dash may light up. Few times I or S.O. has driven off without key (luckily realizing within a few miles of house or location of key). The Avalon will continue to run only having the alert on the dash. I'm guessing my defense here would be to let the batteries die in the fob. Ill still get most of the functionality without the risk. Keeping the battery one (when I want to sacrifice security for convenience) stored in a cage. Really like the attack though.
