Electric car door locks operate using an electronic control module connected to an actuator within each door. When the driver presses the lock/unlock button on the key fob or inside the vehicle, a signal is sent to the control module, which then triggers the corresponding actuator to either lock or unlock the door. The actuator is a small motor that physically moves the locking mechanism. This mechanism can be a rod, cable, or directly connected to the door latch.When the door is locked, the actuator engages, preventing the door from being opened from the outside.Additionally, modern systems often include security features like auto-locking after the vehicle starts moving or remote operation through smartphone apps, enhancing convenience and safety.
