What's the reason when the front passenger door suddenly cannot be opened from both inside and outside?

[Roberto]

The reasons why the front passenger door suddenly cannot be opened from both inside and outside are as follows: 1. The remote key is out of battery, causing the door to fail to open. 2. The remote control malfunctions. 3. The door lock mechanism itself is faulty, or the door lock cable is malfunctioning. 4. After the door is subjected to a certain external force, the door hinge and lock pillar become deformed. Solutions for when the door cannot be opened are as follows: 1. Use a spare key. 2. Find a qualified and professional locksmith to unlock the door. 3. Call the after-sales rescue hotline. 4. Use tape to stick to the vehicle's window and forcibly pull open the window glass. 5. Use a sharp object to remove the sealing strip on the door, then insert a wire through the gap to press the unlock button.

A while ago, the passenger door of my car couldn't be opened from inside or outside, which was quite annoying. First, I checked if the child lock was accidentally engaged, as I might have bumped it while getting my kid in the car before. Sometimes the door lock mechanism gets stuck or there's poor electrical contact, so I tried pulling the inner handle hard, and with a click, it opened. Another possible cause is rusted or broken internal door linkages, especially in older cars exposed to high humidity. It's best not to force it open to avoid damaging the door—better to have a mechanic take a look. Regular maintenance like applying lubricant can help prevent this. I've also noticed that some cars tend to have rear door lock issues on bumpy roads, so regularly cleaning door gaps to prevent blockages is good practice. For safety, avoid letting strangers sit in the passenger seat until it's fixed.

In my similar experience, the inability to open the front passenger door is usually caused by a faulty door lock actuator or a blown fuse. First, check the position of the child lock switch, as it's common for owners to accidentally change the settings. Then, try manually pulling the handle forcefully from inside or outside a few times, but avoid using excessive force to prevent breakage. If that doesn't work, it might be due to a short circuit in the wiring or a deformed door frame jamming the lock. A repair shop can easily pry it open with tools. For prevention, check the smooth operation of the door lock every time you wash the car and replace the lubricant regularly. Electronic system failures are uncommon but can occur, such as remote signal interference. Make it a habit to test all doors before driving to reduce the risk of accidents.

The risk of door lock failure is high; don't panic if passengers get trapped inside. If the front passenger door won't open, it might be due to accidental child lock activation or a faulty door lock mechanism. I once encountered a situation where water accumulated in the door seam after rain and froze the lock—thawing it solved the problem. First, check if the interior and exterior handles are loose; if not, seek professional assistance. In emergencies, most vehicles have an emergency release loop inside the door panel. For prevention, regularly remove rust and lubricate the locking mechanism. Safety comes first—avoid carrying passengers until the issue is fully resolved.
