What are the reasons why the car door cannot be opened from the outside?

There are generally several reasons why a car door cannot be opened from the outside but can be opened from the inside: 1. Cable issue: The door trim panel needs to be removed for inspection and repair, as the cable may have come loose. 2. Lock mechanism: The lock mechanism itself may be faulty, and the door trim panel must be removed to diagnose the problem. 3. Setting issue: Click on the vehicle settings to disable the double unlock feature. You can also refer to the manual for detailed instructions on safety settings, which allow you to configure a single press to unlock only the driver's door and a double press to unlock all doors, or set it to unlock all doors at once. 4. Door handle issue: If the driver's side door cannot be opened from the outside, it indicates a problem with the external door handle. In such cases, the door trim panel must be removed for repair. Immediate repair is necessary to avoid affecting vehicle usage. Some older vehicles may also experience issues where the driver's side door cannot be opened from the inside, which is caused by a malfunction in the internal door switch.
Once, my car door wouldn't open from the outside, and I realized there could be several reasons for this. The most common is accidentally activating the child lock on the door, especially for rear doors. This safety feature prevents children from opening the door themselves, but sometimes adults forget to turn it off. Another possibility is that mechanical components near the door handle are stuck, such as a rusted lock mechanism or a broken linkage rod, which may require checking for insufficient lubrication. Freezing is particularly common in winter, where water accumulation in the door gap can freeze and jam the door—I've encountered this several times, and using a hairdryer or de-icer usually solves it. Additionally, a dead battery in the remote key or signal interference can cause the electronic lock to fail, in which case trying the manual key might work. When troubleshooting, first check if the door can be opened from the inside. If it can, the issue is likely external. Regular maintenance, such as monitoring the lock mechanism's condition, can help reduce such problems, as being unable to open the door in an emergency can be quite troublesome.
