When the KEY-OUT message appears on the car dashboard, it indicates that the vehicle is alerting the driver that the smart key is either not inside the car or not within the effective range. The driver needs to check whether the key is inside the vehicle or if the smart key's battery has sufficient charge. Insufficient battery power in the key can result in a weak signal, causing the car to fail to receive the signal. Smart Key: A smart key is a common keyless entry system, also known as a smart key system. Components of a Smart Key: The smart key system consists of a transmitter, a remote central locking control module, a driving authorization system control module (three receivers), and related wiring harnesses that form the control system.

Why can a car move when the clutch is pressed?

Pressing the clutch disconnects the engine's transmission from the wheels, preventing the engine's power from being transferred to the wheels to drive the car. Releasing the clutch connects the engine's transmission to the wheels, allowing the power to be transferred to the wheels, and the car naturally moves. Here is additional information: 1. The function of the clutch: The clutch is one of the most frequently used components. How well the clutch is used directly reflects the driver's skill level and also helps protect the vehicle. 2. The three working states of the clutch: fully disengaged when the clutch is pressed, fully engaged when the clutch is not pressed, and partially engaged when the clutch is partially pressed. When starting the vehicle, pressing the clutch pulls the pressure plate backward, separating it from the friction plate. At this point, the pressure plate and flywheel are not in contact, so there is no relative friction.
