WheezyJoe writes "The Today Show had a piece this morning showing video of thieves apparently using a small device to open and enter cars equipped with keyless entry. Electronic key fobs, which are supposed to be secure, are replacing keys in more and more new cars, but the evidence suggests that a device has been developed which effortlessly bypasses this security (at least on certain makes and models). 'Adding to the mystery, police say the device works on some cars but not others. Other surveillance videos show thieves trying to open a Ford SUV and a Cadillac, with no luck. But an Acura SUV and sedan pop right open. And they always seem to strike on the passenger side. Investigators don't know why.' Police and security experts say they are 'stumped.'"
