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

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.
I've encountered the issue where the car door won't open even after being unlocked, and there are quite a few possible causes. The most common one is the mechanical part of the door lock getting stuck, such as rust after rain or dust accumulation hindering the linkage from turning. Sometimes small stones or branches get stuck in the door gap, preventing the door from opening normally. There's also the possibility of the child lock being accidentally engaged, which typically affects the rear doors, making them only openable from the outside. In winter, doors are prone to freezing, and ice on the sealing strip can lock the door shut. Solutions: gently push the door or tap the edges to loosen any obstructions; spraying lubricant on the lock mechanism can effectively help. If all else fails, try locking and unlocking the car again, but avoid using excessive force to prevent damaging the handle.
The door not opening after unlocking may stem from lock mechanism failures, such as loose linkages, broken springs, or electrical short circuits. When child locks are activated, rear doors cannot be opened from inside—a common misoperation; check if the door edge switch is set to the open position. For vehicles with power door locks, control module malfunctions or blown fuses can interrupt the unlocking signal. Worn linkage components in door handles may also prevent pulling the latch. External factors like freezing or debris stuck in door gaps can cause doors to jam. It's recommended to first attempt simple resets by locking and unlocking several times; if the issue persists, professional diagnosis is needed, potentially requiring door lock replacement or lubrication of the transmission system. Regular maintenance should focus on cleaning and rust prevention.
