What are the reasons for being unable to open the car door after unlocking?

[VanJaxon]

The main reasons for being unable to open the car door after unlocking are either a faulty exterior door handle cable or a malfunctioning door lock mechanism. Below are some introductions about remote keys: The working methods of remote keys can be divided into three categories based on their usage: active working mode, passive working mode, and coil induction mode. Extended content: 1. The car will compare the received signal with the information stored internally. If the verification is successful, the car will unlock the door. Once the driver enters the car, simply pressing the start button will start the car engine. 2. When the button is triggered, the PKE system first needs to detect whether the "key" device is inside the car, and then complete the same authentication process before starting the engine. When the driver leaves the car, simply pressing the door handle will lock the car door. Before the car is actually locked, it will also detect the driver's position and go through the same verification process.
