Will the car door lock automatically if not locked?

[DiElijah]

There are two scenarios where forgetting to lock the car door may result in automatic locking: 1) If the remote control was used to lock the car initially, but the unlock button was accidentally pressed without anyone actually opening the door, the car will automatically relock within a short predetermined time. 2) However, if someone has opened the door, the automatic relocking function will be disabled. Importantly, when the engine is turned off and the key is removed but the car isn't locked via remote, the doors won't automatically lock even after an extended period. Key points: 1) Active locking: Forgetting to lock a parked vehicle happens frequently, which poses theft risks for belongings inside and creates significant inconvenience. Normally, drivers must actively lock the car using the remote key after removing the key, cutting power, and closing doors, as most vehicles lack key signal distance detection capability for automatic locking. 2) Automatic locking: Vehicles with this feature typically have a small indentation, protrusion, or square pattern near the mechanical keyhole on the driver's door handle. This function greatly simplifies locking - with keys in a bag, simply touching the door handle upon exiting triggers automatic locking.
