If the vehicle is equipped with an automatic locking or anti-theft system, the car doors may automatically lock when the key is left inside. However, vehicles with keyless entry systems will not experience this issue. Solutions include using a spare key or contacting a locksmith. Automatic Locking: The design purpose of automatic locking is to prevent vehicle theft and enhance driving safety. After closing the door, the system will automatically lock the doors after a specified period to prevent situations where the owner forgets to lock the car after turning off the engine or where the doors accidentally open during driving. Keyless Entry: Keyless entry vehicles typically feature push-button start, eliminating the need to insert or remove the key. Therefore, the key is usually carried by the owner, significantly reducing the chance of leaving it inside the car. Additionally, the door handles of keyless entry vehicles often have touch-sensitive fingerprint functions, so even if the key is left inside, there is no need to worry. Prevention Methods: When exiting the vehicle, always turn off the engine, remove the key, and keep it with you. If you must exit the vehicle while it is still running, ensure the handbrake is engaged, the door is not fully closed, or the window is rolled down. Furthermore, when retrieving items from the trunk, avoid placing the key inside the trunk.
