If you don't have the car key with you, the car won't start. Here is some information about car keys: 1. Car Smart Key: The car smart keyless entry system, abbreviated as PKE, adopts the world's most advanced RFID radio frequency technology and the most sophisticated vehicle identity coding recognition system. 2. Principle: This smart key can emit infrared signals to open one or two doors, the trunk, and the fuel filler cap, and can also operate the car's windows and sunroof. More advanced smart keys resemble a credit card. When the driver touches the door handle, the central locking control system activates and emits a wireless query signal. After the smart key card responds correctly, the car lock automatically opens.
