A person standing a few steps away pulls out a phone, and your doors pop open while you stand there watching with no idea how. <strong>More than 2.2 million cars run this box, and getting in takes no key and leaves no mark.</strong></p> <p>When you buy a car at a dealership, the sales desk often offers a security upgrade called <strong>KARR</strong>. A small device gets wired in under the dashboard on the driver&rsquo;s side, and it talks to an app on your phone over Bluetooth. Through the app it behaves like a key fob: it locks and opens the doors, honks the horn, flashes the lights, and it can stop the car from starting. Dealers use it to keep track of the cars on their lot and to sell theft protection to buyers. The names to look for are <strong>KARR</strong> and <strong>SWDS</strong>, which stands for SouthWest Dealer Services, and the company behind the hardware is <strong>Acrisure</strong>.</p>
