How to steal a car easily!

The Electronic Key Impressioner consists of a sensor that goes into the lock and sends information back to a computer via USB about the location of the lock's tumblers—a corresponding computer program comes up with the code, depending on the make of car you've entered beforehand. Once you know the code, a key-cutting machine can use it to carve up a key. The current prototype works only for Fords—Randall's next step is to program the machine to work with cars from a wide range of companies. Some keys are more complicated than this system can anticipate. For example, many car keys have transponders in them, so even if a newly cut key can open a car, it won't be able to start it. But tools exist already for locksmiths to crack transponder codes—and there are plenty of cars out there that still use simple, old-fashioned key technology. [thanks to Popular Mechanics]
