Police are searching for thieves who drove off with three BMW cars from the same driveway in Dobbs Ferry.

Susan Katz tells News 12 she woke up Saturday morning to the sounds of thieves speeding away with her three BMWs. The cars are estimated to be worth more than $200,000.

Each luxury car had a push-button ignition system. Police say the thieves possibly used a high-tech illegal device that can start cars that have push-button starters, without having the key inside the vehicles.
