New York Times reporter Nick Bilton saw a girl use a $17 “power amplifier” to break into his car. Thieves can use the device to boost key searching capabilities, sometimes up to 100 meters. Bilton contacted a security researcher who said some sophisticated thieves have laptops equipped with a radio transmitter. The best way to protect your vehicle if it has a keyless entry system is to “put your keys in the freezer,” he said. The expert said some of the devices cost as little as $17 and can be bought online on eBay, Amazon and Craigslist.”]
