This means that every time the button on the remote key is pressed, the signal sent will change. This technology is designed to increase security and prevent signal interception and replay attacks. Every time the button is pressed, the remote control generates a new encrypted code, which has a mathematical relationship with the previous code but is unpredictable for eavesdroppers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFrequency modulation: Although the operating frequency of the remote key (such as 315 MHz or 433 MHz) is fixed, frequency modulation technology is used when transmitting data. This means that the actual transmitted signal will undergo slight changes around the fundamental frequency to encode different information. This modulation makes the signal sent appear different each time\u003c\/span\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0728\/8258\/5670\/files\/66_0941466e-c39d-450e-8b05-824c3e6561b4.jpg?v=1778548482\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0728\/8258\/5670\/files\/70_90ca5871-7926-4b8d-8d92-f9602ad8c3d0.jpg?v=1778548515\" alt=\"\"\u003e\u003c\/p\u003e","brand":"XJY locksmith Supermarket","offers":[{"title":"Default Title","offer_id":45030338494534,"sku":null,"price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0728\/8258\/5670\/files\/66_536f30b4-4b6f-4af8-a1c6-bc6fef88f37f.jpg?v=1778548537","url":"https:\/\/xjykey.com\/products\/aikkey-k3-remote-key-frequency-tester-with-display-portable-100-999mhz-signal-ask-fsk-ignition-coil-door-handle-signal-detect","provider":"XJYKEY Supermarket","version":"1.0","type":"link"}
