Keyless entry makes it almost unbelievably easy for a hacker to unlock your vehicle

[Jose Barrientos] Hacking into a car using SDR, with a few GNUradio scripts I put together. Given the simplicity of the attack, it is only a matter of time before this is the standard way people steal cars. [Maze] Since all that's really needed is a computer and an antenna, and it's possible for people to write their own smartphone apps, I wouldn't be surprised if it can be done with a phone. But that's just a guess. In any case, I don't think this technique could be used to actually steal your car, but it can definitely get the doors open, so it's another good reason not to leave anything valuable in your car.
