The keyless entry system is a key with an intelligent electronic chip. Some models of Honda, Toyota, Nissan, Mercedes-Benz, BMW, etc. have adopted the keyless system. The smart key can lock the key itself to prevent the owner from being locked out. It should be noted that vehicles with keyless entry function may not necessarily have keyless start function. This product adopts RFID radio frequency technology and vehicle identity coding recognition system, taking the lead in applying the development scheme of miniaturization and small-power radio frequency antenna, integrating remote control system and keyless system, and following the traditional vehicle circuit protection to achieve dual radio frequency system.
