What is the reason why the front passenger door of the Emgrand GL cannot be opened from both inside and outside?

It may be due to a malfunction of the lock block, and it is recommended to go to a 4S store for repair. Below is relevant information about car doors: Integral door: The inner and outer panels are formed by stamping and hemming a single steel plate. This production method requires a higher initial mold investment cost but can reduce the need for related inspection tools and fixtures, though material utilization is lower. Split door: It is composed of a door frame assembly and inner and outer panel assemblies welded together. The door frame assembly can be produced by roll forming, which has lower costs and higher productivity. The overall mold cost is relatively low, but the later inspection tools and fixtures cost more, and the process reliability is poorer.
Encountering an issue where the front passenger door of the Emgrand GL cannot be opened from either inside or outside, I think it might be due to the child safety lock being accidentally engaged. Although in most cars this feature is primarily designed for the rear doors, some versions of the Emgrand GL have a similar mechanism for the front passenger door. The lock is located as a small latch on the inner side of the door frame—try moving it to see if it loosens. Another common cause is mechanical jamming of the door lock, similar to rust buildup in old locks, especially after car washes when moisture seeps in or during cold winter weather when freezing makes the mechanism less responsive. Spraying some WD-40 rust remover and trying multiple times might help. It could also be that the connecting linkage between the inner and outer door handles is broken or deformed; if pulling the door feels loose and unresponsive, this is likely the issue. If the Emgrand GL is a high-end version with electric controls, check the fuse box for any blown fuses or unstable power supply. In any case, avoid forcing the door open, as this could worsen the damage or even harm the door structure. Developing a habit of drying door seams and corners after car washes and applying lubricant every few months can prevent many such problems. If you encounter this situation, it’s advisable to first attempt a quick self-check, and if that doesn’t work, promptly schedule an appointment with a professional repair shop for a fast and safe resolution.
As an old friend who often drives this car, I've seen quite a few cases where the front passenger door won't open from inside or outside. The common root causes for the Emgrand GL include the linkage rod inside the door lock mechanism falling off or bending, making the door handle either stiff or too loose with no response. Another issue could be the door limiter malfunctioning, causing the door to get stuck at a certain angle and not move. Additionally, if it's an electric door, a faulty control circuit board or motor can cause it to completely fail—the Emgrand GL's mid-to-high trim levels often come with this feature, so it's essential to first check if the fuse has blown or if there's poor contact in the plug. A simple trick is to try manually unlocking it by turning the key back and forth a few times. If that doesn't work, it's time for repairs. From my experience, similar issues can be fixed for just a few dozen to a hundred bucks, but the key is not to delay and let dust build up, which can increase repair costs. It's also important to clean the door gaps after every long trip to prevent sand and gravel from clogging them.
The front passenger door of the Emgrand GL cannot be opened from either inside or outside. Start with basic checks. Common causes include accidental activation of the child safety lock—try toggling the button on the door edge; or the lock cylinder being jammed due to excessive dust accumulation, which requires cleaning. If it's a linkage rod failure, there will be a noticeable change in the feel when pulling the door handle, possibly indicating a break. For electric models, check if the fuse is blown. If simple lubrication doesn't work, proceed to repair.
This issue is quite dangerous and affects safety! Owners of the Emgrand GL, don't rush to force the door open as it may worsen the damage to the lock mechanism. The first thing to check is whether the child safety lock is activated—it's located on the door frame and can be easily triggered. Another possibility is rust or jamming in the mechanical parts, especially during rainy or cold weather, which can cause sluggish operation. A broken linkage is also a common root cause. If trying to unlock with the key doesn’t work, stop immediately and call a professional—don’t take risks. Regular maintenance and lubrication of the door locks can greatly prevent these issues, ensuring peace of mind while driving.
