Will the Car Lock Itself If the Key Is Left Inside?

[NaomiRose]

If the car key is left inside the vehicle, the car will lock itself. After the engine is turned off, if the doors are closed without taking the key out, both the doors and the trunk will automatically lock after a few minutes. The functions of a car key include: 1. Automatically closing the windows after the engine is turned off; 2. Helping locate the car in a parking lot; 3. Automatically opening the trunk; 4. Remotely opening the windows. Types of car keys: mechanical keys, remote keys, touchscreen LCD keys, and smart wristband keys. Precautions for using car keys: 1. Do not place them near electronic devices; 2. Avoid exposing the key to direct high temperatures; 3. Do not use batteries with different power ratings.
