Car doors have an automatic locking system, also known as a smart car door lock. The driver can lock or unlock the doors by pressing a switch or pressing a button. This lock is hidden in the car door. The system features battery-powered actuators and small electric motors.

The DC motor (FT-280SA-18182B) has low noise, high torque, high performance, and long lifespan, making it an optimized solution for vehicle door lock systems.
