smart key

Mercedes-Benz CLK has adopted a smart key, which can emit infrared signals, can open one or two doors, trunk and fuel filling hole cover, but also can manipulate the car's windows and skylights, more The advanced smart key is like a credit card. When the driver touches the door handle, the central lock control system starts working and sends a wireless inquiry signal. After the smart key card responds correctly, the lock is automatically opened. The engine will only start when the CPU senses that the key is stuck in the car.
