What to Do When the Car Won't Lock?

[DeDerek]

Solutions for car doors that won't lock: 1. First, check whether the four doors, trunk, and front hood are properly closed. Also, inspect each lock mechanism and control circuit for any open or short circuits. 2. Doors that won't lock are usually caused by issues with the door lock mechanism, lock actuator, or circuit faults. 3. It is recommended to take the car to a repair shop for inspection. This is a complex issue that requires removing the door panel, which is labor-intensive and not recommended for DIY. 4. Determine whether the central locking motor is malfunctioning or if the door simply won't close. If the door won't close, the issue lies with the lock mechanism. If the door closes but the motor doesn't work, the central locking motor is likely damaged.
