The idea behind this invention is to have several radio frequency (RF) devices installed in the parking lot in a well organized manner. The RF device would receive the signals from the keyless entry devices, amplify those signals and emit them out using RF emitters. The rays emitted by this device would be received by the cars around the device. When the signals are received by the car, the car would beep and indicate its location. The RF signals would also be received by similar devices that are arranged at a particular distance from the first device. Those devices will in turn amplify and emit the RF signals received from the first device. In such a fashion, the entire parking lot will be covered. So a car parked anywhere in the parking lot can be detected
