The invention provides a PEPS (passive entry and passive start) technology-based key positioning method. The method is applied to a key positioning system based on the PEPS technology. The system adopts an antenna for positioning a key. The method comprises the steps that the antenna transmits a signal according to preset requirements; the key receives the signal transmitted by the antenna, and the position of the key is determined according to the received signal on the basis of preset conditions. According to the invention, the key is positioned only by the antenna, whether the key is positioned inside or outside a vehicle is determined, in this way, the cost of the PEPS system is lowered, resources are saved, and the reliability of the product is improved.
