What is the reason why the right rear door cannot be opened from the inside?

It may be due to the child lock being engaged. Here is the relevant explanation: Suggestion: It is recommended to check a sliding switch on the side of the right rear door. In most cases, this is a normal phenomenon. Generally, the rear door locks are equipped with child locks, which function to prevent children from mischievously pulling the door open from the inside without adult supervision, thereby avoiding potential dangers. Additional note: The child lock toggle is usually located on the side of the rear door, accompanied by an image of two locks. Toggling the switch to the lock position activates the child lock, making it impossible to open the door from the inside. The door can only be opened normally from the outside at this time.
I recently encountered the frustrating issue of the right rear door not opening from the inside. That day, I was in a hurry to take my family out, and the person in the back seat couldn't open the door no matter what, which was really stressful. The most common cause is the child safety lock being engaged—this is designed to prevent kids from messing with the door. The switch is usually located on the side or bottom of the door, and you can manually turn it off. In my case, it was accidentally triggered by a child playing in the back seat. If it's not the child lock, it could be that the door lock linkage has come loose or broken, especially in older cars after prolonged use. Sometimes, the lock cylinder gets jammed due to dust and grime buildup, making it less responsive—a bit of lubricant or cleaning can fix that. Slight door deformation or something stuck in the door gap can also prevent opening, so check if the door edges are aligned. My advice is to first quickly check the child lock switch and turn it off to test. If that doesn’t work, avoid forcing the door handle, as it might cause further damage. Regularly applying anti-rust oil to the door lock to keep it lubricated is crucial for longevity and reducing malfunctions. This issue really wastes time, so next time, I’ll make sure all doors open and close properly before getting in the car to avoid embarrassment and risks.
As someone who enjoys tinkering with cars, I'm quite familiar with the issue of doors not opening. The first suspect is usually the child safety lock being engaged—a small switch hidden on the side of the door that can easily be accidentally activated by keys or debris. Checking and turning it off typically solves the problem immediately. If that's not the cause, the internal door lock mechanism might be faulty, such as a disconnected or broken linkage rod, which requires opening the door panel to inspect. Sometimes, the lock cylinder gets stuck due to rust, and a quick spray of WD-40 lubricant can do the trick. A blown fuse in the power lock system could also prevent unlocking—just locate and replace the relevant fuse in the fuse box. Don’t forget to check for any obstructions in the door; accumulated debris needs to be cleared out. I recommend starting with simple troubleshooting steps: manually toggling the child lock, pushing the door to check for looseness, and applying basic lubrication. If these don’t work, replacing parts or seeking professional repair may be necessary. DIY fixes can save money, but make sure to have basic tools like screwdrivers and lubricants on hand. Keeping locks clean and dry is key to prevention—I lubricate mine quarterly to minimize wear.
