What is the reason for the automatic jump of a car door lock after it is locked?

First of all, check whether the door is closed properly, if it is not closed properly, it will automatically jump. There is also whether there has been a collision, which may have touched the sensor of the car door, causing the computer to think that the door is not closed properly. If you don't have the above situation, you should go to 4S to check it, there may be a little problem with the circuit.

The central lock in the car refers to the switch located on the driver's door, which is a control device that can control the closing and opening of the whole car door at the same time.

The working principle of the central control door lock is to convert electrical energy into mechanical energy.

The motor is used to turn the gears to open and close the door. The basic components are mainly composed of door lock switch, door lock actuator, and door lock controller.

1) Door lock switch: The switch of most central control door locks is composed of a main switch and a sub-switch, the main switch is installed on the door next to the driver, and the main switch can lock or open all the doors of the whole car; The sub-switch is mounted on each of the other doors and can control one door individually.

2) Door lock actuator: The door lock actuator is controlled by the door lock controller to perform the locking and opening tasks of the door lock. There are mainly electromagnetic and DC motors.

and permanent magnet motors.

Formula three structures.

3) Door lock controller: provide the control device of locking the pulse current for the door lock actuator, have the function of controlling the direction of the energized current of the actuator, and at the same time have the function of timing in order to shorten the working time. According to its control principle, it can be roughly divided into:

There are three types: transistor, capacitive, and speed-sensing.

There are three possibilities: First, the door lock machine is not lubricated enough. Add lubricating oil to each door locking machine; Second, the central control motor is not strong enough.

To check which motor has a problem and give a replacement; Third, if your remote lock is installed, it is also possible that the length of a central control motor push rod has not been adjusted well.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! After the vehicle appears to be locked on the door, it will be automatically opened, normal, the common fault is that the door trigger switch is not good or the door lock is not good, check whether all the state of the door is closed, whether there is a door not, close in place, check whether the door status data flow appears A door has actually been closed, but the data shows that the vehicle is automatically disconnected after the vehicle is locked in the open state, and the door is automatically opened when the door is locked.

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

You are a good model, I am your exclusive technician, attentive, careful, concentrate on answering your car questions, find the corresponding problem solutions and solutions for you and clear the way! After the vehicle appears after the door is locked, it will be automatically opened, normal, the common fault is that the door trigger switch is not good or the door lock is not good, check whether all the absolute state of the door is in a closed state, whether there is a door not, close in place, check whether the door status data flow appears A door has actually been closed, but the data shows that the vehicle is automatically disconnected after the vehicle is locked in the open state

Summary. Hello, dear, I'm honored to answer for you! <>

The reason why the car door lock is automatically locked immediately after unlocking is that the internal lock function of the driver's door of the vehicle is stuck, that is, the driver's door is locked at all times, and the door will work normally when unlocked with the remote control at this time, but it will enter the lock state again, and this situation needs to be reset by pressing and holding the unlock key of the vehicle for 10 seconds, and the central lock will be restored to the normal state after the reset operation, and the specific operation steps are as follows: 1. Open the driving door. 2. Press the brake pedal.

3. Press the one-button start button. Fourth, the dashboard lights up. 5. Press and hold the door unlock button for 10 seconds to reset.

Why does a car door lock automatically lock immediately after unlocking?

Hello, dear, I'm honored to answer for you! <>

The reason why the car door lock is automatically locked immediately after unlocking is that the driver's door inside the vehicle is locked to the car can be stuck, that is, the driver's door is locked at all times, at this time, the door will work normally with the remote control to unlock, but it will enter the lock state again, this situation needs to press and hold the vehicle's unlock key for 10 seconds to reset, and the central lock will return to the normal state after the reset operation, and the specific operation steps are as follows: 1. Open the driving door. 2. Press the brake pedal.

3. Press the one-button start button. Fourth, the dashboard lights up. 5. Press and hold the door unlock button for 10 seconds to reset.

The meaning of the car lock is that there is usually a lock logo on the dashboard of the car, which is actually the anti-theft device of the engine of the car in the car of the company. The anti-theft device can effectively prevent the car engine from being stolen by non-criminals, and improve the safety factor of the car. If someone starts the car with other keys, the "one car, one lock" sign on the car dashboard will always be on, indicating that the engine anti-theft Huai Sheng device on the car dashboard does not recognize the key and only starts the motor.

Reasons why the car door is locked and opens automatically:

1. There are many reasons for the failure of the remote control key, one is that the battery is out of power or the battery is not in good contact; In the second case, the time control module in the remote control key fails, which will also cause the remote control to not work; The third situation is that the antenna of the remote control transmitter on the car is aging, etc., which will also cause this situation;

2. In this case, you can go to the maintenance station to check and repair it. In addition, after some car front windshields are pasted with explosion-proof solar film, when the remote control door is opened directly in front of the vehicle, there will also be a phenomenon that the remote control door lock does not respond, this is because this explosion-proof solar film shields the remote control signal to a certain extent;

3. In the process of use, for the Zhitong remote control key, it is necessary to avoid contact with some strong magnetic fields, such as high-voltage lines, transmission towers and other places where there are strong magnetic field signals, try to avoid vehicle parking, because the smart key uses low-intensity radio waves, so it may not work normally in the case of magnetic field interference;

4. In addition, try not to throw away the smart key when using it, because most smart key shells are relatively strong, but frequent drops will lead to poor contact with the internal battery.
