What should I do if the deadbolt of the car door lock can t go back?

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. Crashworthiness is particularly important.

Design requirements for car doors:

1. Ensure the convenience of passengers getting on and off the bus, and the maximum opening is controlled at about 65° 70°.

2. There should be no position interference with other parts during the opening process.

3. When the door is closed, it should be locked reliably and will not open by itself while driving.

4. The door mechanism is easy to operate, including the free closing of the door, the light lifting of the glass, etc.

5. Good sealing performance requirements.

6. It has a large translucent surface to meet the requirements of lateral vision.

7. It is necessary to have sufficient strength and rigidity to ensure that the door works reliably, reduce the vibration of the door part, improve the safety of the vehicle lateral collision, and prevent the door from sinking.

In general, the door lock tongue cannot be retracted for two possible reasons:

1. One situation is that the lock body is broken, and the transmission mechanism cannot drive the lock tongue to rebound, in this case, the lock body can be replaced.

2. Another situation is the problem of the lock cylinder, the cam (fork) of the lock body can not drive the lock body, resulting in the lock tongue can not rebound; Generally, the marble or the internal structure of the lock cylinder is damaged, and the lock cylinder needs to be replaced.

3. Identification method: first in the case of not dismantling the lock, in the state of the door open, twist the lock cylinder with the key to see if it is smooth, if it is, but the lock tongue still does not rebound, it can be basically determined that it is the problem of the lock body, if the key does not move, you need to disassemble the lock cylinder, test the lock cylinder separately, first to see whether the fork is damaged, and then to see whether it can be twisted, if not, then it is the lock cylinder problem, if it can, then it is still the lock body problem.

It's actually quite simple. It's good to pull the inner handle on the door twice in a row. Hope, thank you.

Remove the snow with a scraper or frost shovel, apply a warm towel, blow it with a hair dryer, and drive the car out into the sun. Through these methods, the problem of the door lock being frozen and not being able to twist left and right can be solved.

Prepare a hard plastic scraper, of course, a special glass frost shovel is better, convenient, fast, and does not freeze your hands. It should be noted that when using this method to remove frost, in order to prevent scratching of the glass, the tools used should not scrape back and forth, but should be shoveled in the same direction.

Pour warm water over the doorknob or the ice in the crack of the door and let it melt slowly. However, it is also important to wipe the water with a dry cloth immediately after the door is thawed, otherwise a thicker layer of ice may form.

If the car is not driven temporarily, you can drive the car to the sun in the sun when the sun is better until the ice is melted, although this method is time-consuming, but it is also a more economical and trouble-saving negative teaching material.

If the door is frozen, do not lower the window immediately after entering the car, as it is usually frozen with the adhesive strip as well. If you force it, it may cause the window glass to break.

1.Loosen the thread buckle with a flat taper, engrave it in the flat groove and knock it with a hammer, which is to loosen the thread buckle.

2.Striking the screw Generally, the locksmith should use a long cross screwdriver to exert force, and after aligning the screw, use a hammer to strike the screwdriver, on the one hand, to make the screwdriver fit and bite.

3.Take out the knife Find a way to draw a cross or a line shape with a hard knife in the circle, and if it is simple, it will be a line and a deep one.

4.Screw in the small screw Use a small drill to punch the round screw first, and then use a reverse wire tap to screw it in to form one inside.

5.Soldering In addition, you can use the method of soldering, heat the solder with an electric soldering iron, drop it on the screws and screwdrivers, cool and solidify, and then you can.

Summary. Hello, the deadbolt of the car door lock can't go back, you can pull the door handle, keep it in the state of holding it all the time, and use a screwdriver to pick the deadbolt to return the deadbolt to the correct position. If the return spring inside is damaged, you need to replace the door lock, I hope mine can help you.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, the deadbolt of the car door lock can't go back, you can pull the door handle of the Xiantanji, keep it in a state of pulling, and pick the deadbolt with a screwdriver to return the deadbolt to the correct position. If the return spring inside is damaged, you need to replace the door lock, I hope mine can bring you brother and help.

The deadbolt cannot be retracted, the door cannot be opened, and it is locked because the lock body is broken, resulting in the inability to rebound. The reason why the door can not be opened is that the lock body of the door is broken, resulting in the transmission mechanism having no way to drive the lock body to rebound, at this time, the deadbolt can not be retracted and the door can not be opened, and the door lock must have safety and stability as a safety product.

A brief description of the door lock

Door lock as a security product must have security can be measured from two aspects, one is to resist vandalism, pranks and deliberate prying, drilling and other violent destruction, in this regard, the mechanical strength of mechanical locks and electronic door locks can generally meet the requirements, and among all kinds of door locks, only the radio frequency card electronic door lock is a fully enclosed structure, and its security is the best.

The second is to prevent the opening of technology, and the ability of mechanical locks to prevent technology opening is very poor, regardless of the structure of mechanical locks, they can be opened by other means. The key can be copied is a great security hazard, in the electronic door lock magnetic card is not limited by the password, and the key card is easy to be copied. IC cards and RF cards completely solve the problem of turning on the prevention technology.

As a door lock, its stability is also very important. Failing to open the door when it should be, and failing to close the door when it should be done can cause serious losses to financial companies. Generally speaking, among several electronic door locks, the stability of RF card electronic door locks is significantly higher than that of other electronic door locks, magnetic cards are afraid of strong magnetic fields, IC cards are afraid of oil, dust and static electricity, while RF cards have the characteristics of full sealing, waterproof, anti-static and dust-proof.

I moved the deadbolt of the car door lock, and then the door couldn't be closed, what happened?

Reasons why the car door cannot be closed: the hinge of the door or the door lock clip is displaced, the door lock tongue cannot be reversed, the contact switch problem of the door lock is closed, and the height of the contact installation is not enough. Here's how to fix it:

Pi J 1, open the door, and use the T-20 spline to loosen the screws in the small hole on the side of the door. 2. Remove the small cover of the doorknob. 3. Loosen the cable in the card slot of the door handle.

4. If the above methods still cannot be solved, it needs to be sent to the 4S store for replacement or repair as soon as possible. The function of the car door: to provide a passage for the driver and passengers to enter and exit the vehicle, isolate the interference outside the vehicle, and reduce the side impact to a certain extent.

Hello, I am Teacher Zhang, who has been teaching for 10 years, a general knowledge in the field of education, and I hope to help you through my experience and knowledge. The reason why the door lock tongue can't enter the card slot is generally because the door is deformed or sagging, and the lock tongue can't be locked into the card slot smoothly. Solution:

1. The door is sagging, that is, you need to lift the handle to lock the door or open the door; Then use a steel file to file the lock on the door frame downwards as a whole, until the door is no longer required to lift the handle. 2. The door is deformed vertically, that is, the lock can be locked by pulling the door hard, and there will be a sound of collapse when the door is opened; Then you need to file in the direction of the door opening with a steel file (file the inside door in the direction of the house, and vice versa). I'm done, I don't know if you still have any questions.
