Solutions for the key symbol appearing on the vehicle: When the key symbol is displayed on the vehicle, it indicates that the vehicle cannot detect the car key. This could be due to a malfunction in the vehicle's receiving module, a failure in the key's transmitting module, or simply a dead battery in the key. In such cases, it is necessary to promptly replace the vehicle's receiving module, replace the key's transmitting module, or change the key's battery. The car's smart keyless entry system utilizes RFID radio frequency technology and a vehicle identity code recognition system. It pioneers the development of a compact, low-power RF antenna solution and successfully integrates remote control and keyless systems while maintaining traditional vehicle circuit protection. This truly achieves a dual RF system and dual anti-theft protection, providing convenience and security for car owners.
