The reasons for the malfunction of the keyless entry system button: 1. The car battery is dead; 2. The car key battery is dead. The car keyless entry system uses RFID radio frequency technology and vehicle identity code recognition system, applies miniaturized, low-power radio frequency antennas, and integrates the remote control system and keyless system, while retaining the traditional vehicle circuit protection, truly achieving a dual radio frequency system and dual anti-theft protection. The functions of the car keyless entry system are: 1. Automatic window raising and arming function; 2. Wireless remote control function; 3. Anti-theft alarm function; 4. Online diagnostic function.
