Why Can't the Rear Doors Open After Unlocking the Sagitar?
1 Answers
The reasons why the doors cannot be opened after unlocking: This situation is usually caused by a fault in the outer door handle cable or the door lock mechanism. The specific cause needs to be checked at a 4S store or auto repair shop. How the remote key unlocks the doors: The working methods of the remote key can be divided into three categories based on usage: active working mode, passive working mode, and coil induction mode. Active working mode: The principle is to control the doors through the vehicle's electronic control unit (ECU) and body control module (BCM). Simply pressing the key button sends an unlock/lock command, which, after verification by the vehicle's electronic module, opens/closes the doors. Coil induction mode: Mainly involves placing an encrypted chip inside the key. During the unlocking process, the vehicle's radio frequency transceiver verifies whether the key matches to determine if the engine can be started. This is primarily used in special cases where the key has no battery, allowing the car to start normally. Passive working mode: When the owner enters the sensing area of the key system, as long as they touch the door handle, the identity-recognizing 'key' they carry will receive a low-frequency signal sent by the car. If this signal matches the identity recognition information stored in the 'key,' the 'key' will be awakened. After being awakened, the 'key' will analyze the authentication command sent by the car and send a corresponding signal, which is encrypted to enhance security.
