What is the working principle of the central door lock system?

[MilaDella]

The working principle of the central door lock system is to generate electromagnetism through electrification, and use electromagnetic suction to control the locking and unlocking of car doors. Central control is the abbreviation of central control. There is a button on the driver's door. After pressing it, the door locks and windows of the other three doors cannot be controlled separately, and must be operated by the driver alone. Conversely, they can be controlled separately. The main function is to prevent children from accidentally opening the door while driving and to prevent unwanted individuals from opening the door from the outside. Once the door lock is engaged, the other doors and the luggage compartment door can be automatically locked. Using the key to lock the door can also simultaneously lock the other doors and the luggage compartment door. When the driver's door lock is lifted, the locks of the other doors and the luggage compartment door can be opened simultaneously by using the key switch to achieve this action.
