Can anyone steal a car if its equipped with Smart or Intelligent key?

Can u start a car with the push button when there is no key present in the car. The vehicle has to detect the chip in the smart key in order 2 start.





Does anyone have any knowledge about this?





Thanks.|||Of course - even with anti-theft technology, no car is truly theft-proof. Many of the modern keys (i.e. Smart key) uses RFID to transmit the signal from the key to the car, rather than the old resistance technology. While it is more difficult, a tech-savvy thief can either hack or capture the RFID, effectively telling the car that the key is present. Likewise with the "smart" key fobs.





This is difficult, since some of the systems go all the way up to 128 bit encryption, but it is not impossible, since most any short range wireless communication systems like that can be hacked.





I think the TI guys did a demonstration on something like this a few years back, using a laptop, antenna, and brute force hacking - prior to the 128 bit days.|||What car?|||In general, the car can't be started without the proper key. However, it can be stolen by tow truck, which is becoming increasingly common.





Some systems are not as secure as others. Many disable the fuel pump when the proper key is not used, but the fuel pump can be hot-wired. GM Passlock systems can be defeated by leaving the key in the "run" position for ten minutes (it is in the owner's manual for my daughter's 2004 Classic), which strikes me as odd.
