What to Do When Car Doors Suddenly Won't Lock?

[ValerieFitz]

Here are the solutions for car doors that won't lock: 1. Method 1: Check if the doors, trunk, and hood are properly closed. 2. Method 2: Inspect each lock mechanism and control circuit for any open or short circuits. 3. Method 3: Replace the door lock mechanism, latch actuator, or central control motor. Below is additional information on why the car won't lock: 1. Reason 1: The remote lock is malfunctioning, or the antenna of the car's remote transmitter is aging, causing the remote key to be ineffective. 2. Reason 2: Faulty door lock mechanism, latch actuator, or central control circuit. 3. Reason 3: Strong magnetic field interference around the car prevents the remote key from functioning properly. 4. Reason 4: Rust increases resistance in the locking mechanism.
