For cars equipped with push button start, thieves using a special electronic device can pickup your IA signal, record it and use it to unlock the door, start the engine and drive away in SECONDS. Check out the video shown on NBC News today.
(Note that the device does not work on cars that start with a key and use a fob).
More information as to how this works:
Basically one person gets within 8 meters of the person who owns the car (carrying the IA) and uses a special receiver to pickup the code it's transmitting. This receiver then re-transmits the IA code to a second person who receives the code and is standing next to the car. (They do not need to be close to each other).
The small unit he's carrying then re-transmits the IA code to the car, and the car thinks it's the original IA fob, allowing the door to open and the car to start. Its already in use.
