Abstract
A method for unlocking and enabling an engine start a motor vehicle using a vehicle key involves the motor vehicle having at least one outer node for wireless connection with the vehicle key outside an interior of the motor vehicle, at least one inner node for wireless connection with the vehicle key inside the interior of the motor vehicle, and a control system. The method involves first producing a wireless connection between the vehicle key and the outer node, and then unlocking the motor vehicle. The method then involves forcibly ending the existing wireless connection between the vehicle key and the outer node and then forcibly producing a new wireless connection between the vehicle key and the inner node.
