Why can't the car door be opened from inside after unlocking?
2 Answers
The main reasons why the car door cannot be opened after unlocking are either a faulty exterior door handle cable or a malfunctioning door lock mechanism. Here is expanded information: 1. Principle of door lock operation: The car compares the received signal with the information stored internally. If verification is successful, the car will unlock the door. Once the driver enters the vehicle, simply pressing the start button will initiate the engine. When the button is pressed, the PKE system first checks whether the 'key' device is inside the car, then completes the same authentication process before starting the engine. When the driver leaves the car, pressing the door handle once will lock the doors. Before actually locking, the car also checks the driver's position and goes through the same verification process. 2. Working methods of remote keys: They can be divided into three categories based on usage: active mode, passive mode, and coil induction mode.
I've also experienced the issue of not being able to open the car door from the inside, especially when going out with kids. That time when the car was parked by the roadside, I sat in the back seat ready to get out, but couldn't pull the handle even though the door was unlocked, making me sweat with anxiety. Later I learned it was because the child safety lock was activated – a small switch by the door can lock the interior handle when turned, preventing children from opening the door randomly while driving. This isn't a malfunction, but a safety feature. If the switch is off and it still doesn't work, it might be that the door lock linkage has fallen off or is stuck in some position, requiring a visit to the repair shop. In winter, doors sometimes get stuck due to freezing or dirt buildup, where spraying some lubricant or gently tapping might help. In any case, when encountering this situation, don't force the handle – first check the settings, then consider mechanical issues, safety always comes first.
