A New Wireless Hack Can Unlock Almost Every Volkswagen Sold Since 1995 (arstechnica.com)

Volkswagen isn't having the best of times. Tens of millions of vehicles sold by Volkswagen AG over the past 20 years are vulnerable to theft because keyless entry systems can be hacked using cheap technical devices, reports Wired (alternate source). Security experts of the University of Birmingham were able to clone VW remote keyless entry controls by eavesdropping nearby when drivers press their key fobs to open or lock up their cars. ArsTechnica reports: The first affects almost every car Volkswagen has sold since 1995, with only the latest Golf-based models in the clear. Led by Flavio Garcia at the University of Birmingham in the UK, the group of hackers reverse-engineered an undisclosed Volkswagen component to extract a cryptographic key value that is common to many of the company's vehicles. Alone, the value won't do anything, but when combined with the unique value encoded on an individual vehicle's remote key fob -- obtained with a little electronic eavesdropping, say -- you have a functional clone that will lock or unlock that car. VW has apparently acknowledged the vulnerability, and Greenberg (writer at Wired) notes that the company uses a number of different shared values, stored on different components. The second affects many more makes, "including Alfa Romeo, Citroen, Fiat, Ford, Mitsubishi, Nissan, Opel, and Peugeot," according to Greenberg. It exploits a much older cryptographic scheme used in key fobs called HiTag2. Again it requires some eavesdropping to capture a series of codes sent out by a remote key fob. Once a few codes had been gathered, they were able to crack the encryption scheme in under a minute.

      I have a Luddite coworker who shares your mistaken belief that power windows are some kind of problem. Regular windows fail too, and replacing a power window drive system is inexpensive and easy.

      I think the only failure I've ever had with manual windows is for the $.50 spring clip that holds the crank on gets lost after removing it to fix something else. Power window regulators typically run $100+. I've replaced too many of those to count over the years. Plus the time it takes to do so. I've also had to replace the switches in the passengers doors on occasion, which were relatively cheap. But the two times I've had to replace the drivers side it's the entire switch cluster. That was around $200 each time. And again the time it took to do so. Granted the switches don't take too long, but you have to be careful about removing the inside door clip, or you can break things. That can add a couple bucks for the plastic retaining clips, or could get into the hundreds of dollars if your not careful and break the panel itself.

      Power windows tend to stop working if you are in an accident and end up in water too. I was a passenger once when that happened.
