Keyless Remote Car entry/starter

With smart phones coming up with apps for any use, car are becoming more computerized. Ford being the pioneer with their Ford Sync powered by Microsoft entertainment system.

Ford SYNC is a factory-installed, fully integrated in-vehicle communications and entertainment system that allows users to make hands-free telephone calls and control music and other functions using voice commands. The system consists of applications and user interfaces developed by Ford and third-party developers that run on the Microsoft Windows Embedded Automotive operating system.

The introduction of keyless wireless entry and ignition has made it convenient to just get to your car, open it and turn on the ignition without having to take your key out.

Vehicles equipped with keyless entry systems emit a low-level signal that can only be detected by a key fob paired with the vehicle. When the fob is close enough to the vehicle to detect the signal (typically 20 feet), it automatically issues a command to unlock the doors and enable the push-button ignition. The key fob codes are encrypted but doesn't mean it is fully secure.

researchers at ETH Zurich in Switzerland were able to trick 10 models from 8 manufacturers into thinking the car key fob was within proximity were able to get into the vehicle and drive away without needed any tools other than 2 antennas. How this hack works is using the antennas as a repeater to boost the signal that is emitted from the keyless entry transmitter to about 26 feet while the second antenna catches the signal to put it close enough to the vehicle. 

These features have it's advantages and may need to be worked on to be secured but are a convenience to some of us.
