What does a keyless entry system mean?

[LeEmerson]

A keyless entry system is an intelligent key or smart card that utilizes the world's advanced RFID (Radio Frequency Identification) technology and an advanced vehicle identity coding recognition system. It pioneers the application of a miniaturized, low-power RF antenna development solution and successfully integrates remote control systems with keyless systems, while maintaining traditional vehicle circuit protection. This achieves a true dual RF system and dual anti-theft protection, offering both convenience and security to car owners. Premium automakers such as Renault, Mercedes-Benz, and BMW have already adopted this "keyless" system. When the owner steps within a designated range, the system recognizes them as the authorized driver and automatically unlocks the doors. Once inside, simply pressing a button starts the ignition. Modern smart keys can also "lock" themselves to prevent owners from accidentally locking themselves out of the vehicle.
