What does it mean when the keyless entry function fails?
1 Answers
Keyless entry function failure means the car cannot detect the key, rendering the function inoperative. The most common cause is low battery in either the key or the car. Solutions include replacing the battery, recharging, or temporarily using the spare mechanical key on the key fob. Reasons for function failure: When the car suddenly cannot detect the key, it may be due to electromagnetic interference from nearby signal sources such as surveillance cameras, telecommunication towers, or high-voltage power lines. These can generate interfering signals that prevent the car from detecting the key. If the smart key's battery is depleted, the start system may fail to sense the weak radio waves emitted by the key. In such cases, even with the key inside the car, the dashboard may display "key matching error". Keyless entry system: The automotive keyless entry system, abbreviated as PKE (PASSIVE-KEYLESS-ENTER), incorporates the world's most advanced RFID radio frequency technology and vehicle identity coding recognition system. It pioneers a miniaturized, low-power RF antenna development solution, successfully integrating remote control systems with keyless systems while maintaining traditional vehicle circuit protection. This achieves a true dual RF system with double anti-theft protection, providing maximum convenience and security for car owners. The "automotive keyless system" is not a traditional key but rather a smart key or smart card.
