What is the reason why the rear door of the vehicle won t open from the inside?

First, the handle cable inside the door is damaged or falls off, resulting in the inability to open the door from the inside. Second, the child lock protection device of the rear door is opened, resulting in the door cannot be opened from the car, as long as the child lock is unlocked, the car door can be opened smoothly.

First of all, the first one, if the cable falls off or is damaged, you can first open the door from the outside, and then pull the inner handle to feel whether the inner handle has any force, and observe whether the child lock is locked, if it is not locked, it is necessary to disassemble the door lining plate to replace the cable or fix the cable.

Again, the child lock protector of the rear door is opened, resulting in the door not being opened from the car, as long as the door is opened, the child lock can be opened inside. So what are the forms of child locks?

There are two forms of common child lock switches, one is knob type and the other is toggle type. The knob type child lock needs to be inserted into the lock hole of the child lock with a mechanical key, and the knob switch can be turned to lock and unlock.

Toggle child locks, you only need to toggle the switch up and down to lock and unlock. This can be seen in the position of the rear door latch which form your car is in.

If there is no way to open the vehicle from the inside, at this time the rear door has an emergency escape window, if it still cannot be opened, this situation is because of the control room of the car.

Is it an automatic drop lock or a child lock? If the lock is automatic, the driver's seat should press the unlock or pull the key, and if the child lock is open, the child lock should be opened and the child lock should be unlocked.

Fault Judgment: False Fault.

Reason analysis: the current vehicle is generally installed at the rear door of the vehicle with a child lock, to prevent the child who sits in the back seat from opening the car door due to misoperation, and a safety accident occurs. Many people have moved the handle of the child lock when washing the vehicle because they are not careful, and the occupant in the back seat cannot open the door from the inside.

This is not a fault, just open the door from the outside of the vehicle and move the handle of the child lock to the open position.

There are generally two situations when the door cannot be opened from the inside: the central lock is not opened.

Solution: Press the central control switch of the main driving control panel and open the central lock; Child locks on individual doors are open.

Solution: Open the door outside the vehicle, observe the side of the door, there is a child lock, flip the switch, and close the child lock.

1. The car door is to provide a passage for the driver and passengers to enter and exit the vehicle, and isolate the interference from outside the vehicle, reduce the side impact to a certain extent, and protect the occupants. The beauty of the car is also related to the shape of the doors.

The quality of the door is mainly reflected in the anti-collision performance of the door, the sealing performance of the door, the convenience of opening and closing the door, and of course, other indicators of use functions. Collision avoidance is particularly important because in the event of a side collision, the buffer distance is very short, and it is easy to injure the occupants of the vehicle.

2. There will be at least two anti-collision beams in a good door, and the weight of the anti-collision beam is heavier, that is to say, a good door is indeed heavier. But that's not to say that the heavier the door, the better. In today's new cars, if safety performance can be guaranteed, designers will try to reduce the weight of the vehicle, including the door (such as using new materials) to reduce power consumption.

3. According to the number of doors, the car can be divided into two-door, three-door, four-door, five-door car, etc. Most cars for business use are four-door, cars for family use are four-door, three-door, and five-door (with lift-up doors), and sports cars for sports use are mostly two-door.

The reasons that cause the door to be opened inside and outside are: 1. The child lock is in the open state, 2. The door lock block cable fails, 3. The door hinge and lock post are deformed, 4. The door limiter fails.

1. The child lock is on.

The rear door of the general vehicle has a child lock, located on the side of the door with a child's sign, if you accidentally open it and close the door directly, then the door can not be opened, so when closing the door, you must remember to see if the child lock is closed, if it can't be opened, we need to take out a word to change the cone, and screw the child lock to the closed state, on it.

2. The door lock block cable fails.

If the cable fails, it will directly affect the lock block can not be opened, and after this kind of problem, we can only change the door lock block to pull the wire, so as to make the door reopen.

3. The door hinge and lock post are deformed.

When the door is subjected to a certain external force, it may lead to the deformation of the door hinge and the lock post, which is also one of the reasons why the door can not be opened, after this problem occurs, only the door and the door hinge are disassembled together, and then replaced with a new hinge and lock post, so that the door can be opened and closed normally.

The failure of the limiter is also one of the reasons why the door cannot be opened, after this problem, it is very laborious to open the door, or it cannot be opened at all, and the solution is to replace it with a new door limiter.
