2、How to check if the door cannot be closed normally due to faulty damage
1.1、Lock machine damaged
There are two situations to check the cause of specific losses: first, it is caused by other factors. For example, the buttons of the remote control are damaged, the remote control is out of power, there is strong electromagnetic interference in the surrounding area, and the wiring of the central control system is not in good contact, etc., which may cause the door lock to not sense the call of the owner and cannot open the door, which is not caused by the damage of the lock itself. Second, it is caused by the lock itself. Such as the fuse in the switch line of the door lock machine burned out, strong door closure or wear and the spring of the lock block is broken, the lock machine rust, insufficient pulling force, the lock block lacks lubrication and the back force of the hairpin causes the motor load to be overloaded, etc., the damage of the lock machine and the number of times to open and close the door and the force of opening and closing the door are linked, mechanical failure and the use of door lock materials have a great relationship, which will cause the door lock machine to fail to work normally.
1.2、Damaged internal parts of the lock machine
The main parts inside the lock machine are motors and gears. When the motor has problems such as aging, torque becomes smaller, power drop cannot be combined with gears, the locking machine cannot work.
3、How to replace the correct car door lock machine to solve the problem
The door lock machine is stuck or damaged and cannot work, resulting in the door cannot be opened or the door cannot be closed tightly, the car will trigger an alarm while driving, which will seriously affect the owner's travel safety. Conventional lockdown machine can not be used basically the internal motor or gear is broken, a motor can use 10w+ times of frequency, a motor tested at 1-2w speed, the use of high frequency will cause the motor to have a short circuit. If only the internal parts are broken, the owner buys the motor or gear of the corresponding model to replace the original damaged parts, there is no need to buy a whole lock machine, from the cost performance point of view, the cost of buying a small motor is lower and more cost-effective than the lock assembly.
