It used to be that all it took to steal a car was a slim jim and a deft hand. But as the recent hacks of models like the Toyota Prius and Tesla Model S shows, these days it takes some real technical know-how. Automakers appear to actually be taking this threat seriously, which means they'll be keenly interested in the news that hacker Silvio Cesare in Australia has his own high-tech approach to breaking into a vehicle that is even possible remotely.

Cesare's system uses key fob data to spoof a car's unlock signal, according to Wired. It's done using a tool called software-defined radio to broadcast at the necessary frequency and try several attempts per second until the doors open up. Once complete, he says that the only sign of tampering is that the owner's remote takes a few presses to work again.

If you're paranoid about thieves rolling down your block unlocking everything they see, don't be. Cesare's hack leans more towards an experiment than a realistic tool. While it only takes a few minutes in the video, that isn't a guarantee. The correct code changes each time, and it could take up to two hours to work, according to Wired. A traditional thief could have a car in another state by that time. Also, the hacker needs a portion of the unlock code to get started, and that requires capturing at least one command from the key fob. Finally, Cesare has only tested this on his own vehicle so far. He built a robot to press the button multiple times to capture the possible codes.

Thankfully, Cesare says he has no plans to make his code available to the public and is working to alert to manufacturer. Scroll down to see the hack and the robot in action.

      Nothing impresses the ladies when entering your car like a sign advertising there is used toothpicks and "stink" inside.

      This isn't anything new.  Garage doors have been behind the curve for years.  Although there usually isn't anything good to steal in a typical American's garage anyway - usually packed to the ceiling utter garbage.

      My car has keyless entry and I'd be worried... Luckily it's a 1999 Taurus and nobody wants to steal that!

      Brute force hacks are easy to foil. Three failed attempts should result in the car's alarm sounding with a 10 second delay before it will respond to more key fob input. To avoid false alarms the first part of the signal should always be the same, with a unique ID encoded, to guarantee that the signal is intended for the given car.

        First part of the signal, then could be easily obtained by listening from the genuine remote. That was already needed for this hack. So, they need a better way to deal with the false alarm.

        But good idea otherwise.
