Hi-tech Luxury Car Theft

I was car shopping at the end of last year and looking at the new STS, and one of the features that really intrigued me was the "Keyless Go" (or whatever they call it).  The idea is that you carry around a key-like device (in the case of BMW, it's a credit card thing) that, when in proximity of the car, you can unlock and start it without having to do anything short of pressing a button.  Cool, right?  Yeah, until black hats use RFID sniffers and laptops with mobile transmitters to break the ECU's encryption use the convenient technology for their own deviant purposes.  It's been proposed that this is how Beckham's X5 was stolen, but at least his had a happy ending in the form of a free Audi.

Update:  Sister site Engadget has a similar post - linking to the same article - which talks about the connection between this technique and the Beckham's Bimmer SUV.
