What to Do When the Front Passenger Door Cannot Be Opened from Inside or Outside?

It may be due to a faulty lock mechanism, and you can go to a 4S shop for repair. Below is relevant information about car doors: Integrated 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. However, material utilization is relatively low. Split-Type Door: It is assembled by welding the door frame assembly and the inner and outer panel assemblies together. The door frame assembly can be produced using 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.
I often hear friends complaining about the issue of the passenger door not opening, which is quite common. Possible causes include accidental activation of the child lock or mechanical parts getting stuck—the child lock is designed to prevent children from opening the door randomly, but sometimes it locks the internal handle if not properly deactivated. If the car has another entry point, try climbing in from the back seat first to see if the internal switch works; if not, it's likely that the lock linkage has come off or the spring is rusted. Don't pull hard to avoid damaging the door structure or your nails, and quickly seek a professional mechanic. They can quickly locate the problem with tools and replace parts efficiently. Additionally, in cold northern winters, doors can freeze shut—using de-icer spray might help. Regular maintenance, like applying lubricant to the lock points periodically, can prevent rust and avoid recurring issues, ensuring driving safety is the top priority.
