Keyless ignition systems allow you the convenience of starting your car with the touch of a button, without removing the chip from your pocket or purse or backpack. Like vehicle immobilizers, keyless ignition systems work only in the presence of the proper chip. Unlike remote keyless entry systems, they are passive, don't require a battery and have much shorter ranges (usually six feet or less). And instead of sending a signal, they rely on a signal being emitted from the car itself.

Given that the car is more or less broadcasting its code and looking for a response, it seems possible that a thief could try different codes and see what the responses are. Last fall, the authors of a study from Johns Hopkins University and the security company RSA carried out an experiment using a laptop equipped with a microreader. They were able to capture and decrypt the code sequence, then disengage the alarm and unlock and start a 2005 Ford Escape SUV without the key. They even provided an online video of their "car theft."
