Will the car lock automatically with the key inside?

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 rear hatch will automatically lock after a few minutes. This feature is designed to prevent the owner from forgetting to lock the car. Here is some information about the car key's hold button: 1. Introduction: Holding the hold button for a few seconds opens the trunk, preventing the risk of opening the trunk while the car is in motion, hence the name "hold." 2. Other functions: The hold button is not just for opening the trunk; it is also a remote engine start button. Within a certain range, holding it for 2 to 3 seconds will automatically start the car. This feature is especially useful in winter and summer for pre-adjusting the car's interior temperature.
I once left the car door open, forgot to put the keys on the seat, and when I closed the door, it locked automatically, leaving me stranded outside. Luckily, a neighbor helped out. Modern cars usually don't behave this way because they have key detection systems. If the key is inside the car, the auto-locking feature might be disabled to prevent accidental locking. However, if the system is outdated or malfunctioning, it can still happen. My advice is not to rely entirely on it—it's better to develop a habit of removing the key or confirming its location before exiting the car. Some vehicles have apps that allow remote unlocking, but don't fully trust them. Older cars lack such smart designs and are more prone to issues, requiring extra caution. In any case, if locked out, towing or using a spare key are solutions, but they waste time and money. Nowadays, I pay more attention to the details.
When it comes to car door locking technology, most modern vehicles are equipped with keyless entry systems. Sensors detect if the key is inside the car, so if the system detects the key signal inside, it prevents the automatic locking mechanism from engaging, avoiding locking the key inside. However, older models or basic versions may not have this feature and could lock as usual. Some models, like certain Toyotas or Hondas, are highly reliable but not 100% foolproof—sensor malfunctions can still occur. I’ve tested this a few times by leaving the key inside to simulate locking, and most new car doors won’t budge. Remember to regularly check your vehicle’s manual to understand its specific features. Adding smart modules can enhance security, but the core principle is to never let your guard down.
Generally, cars are designed not to automatically lock when the key is still inside the vehicle, as this poses a risk. The system is designed to prevent accidental operations, such as leaving the key on the seat or dashboard, which may keep the doors unlocked. However, don't assume all cars are the same. I've seen a friend forget the key in an older car, and the doors locked as soon as they closed. Prevention is simple: always confirm you've taken the key out before leaving, or keep it in your pocket instead of leaving it in the car. Newer cars come with more technology, including anti-lock features, but if the battery is weak, the sensors might fail. It's advisable to use a mobile app as a backup. Don't be careless—developing good habits can prevent most issues.
