The method involves determining polling of a vehicle key fob (14) using a Bluetooth signal (20), which is sent by a primary Bluetooth low energy apparatus to check whether the key fob is in predesignated proximity of a vehicle (12). The signal sent by the key fob is received by the primary BLE apparatus, if the key fob is in proximity of the vehicle. Reception power of the signal is determined. The key fob located within or outside the vehicle is determined by using the reception power in settlement proceedings.
