The invention relates to an electronic device for determining the distance between two objects with interrogation signal generating means for generating and transmitting an interrogation signal, response signal receiving means as well as an evaluation unit in the one object and the interrogation signal receiving means and response signal generating means in the other object, as well as to a thus-equipped electronic security system, as a vehicle locking the keyless-go type. According to the evaluation unit for determining a phase difference between entfernungsindikativen interrogation signal and response signal is established. Use eg in motor vehicles to determine the distance of a detected authentication element for an electronic locking system and / or immobilizer of the vehicle.
