Can You Lock the Car Doors Without Turning Off the Engine?

[Jeremy]

You cannot lock the car doors without turning off the engine. Even if some vehicles allow locking the doors while the engine is running, they will automatically shut off after locking the doors. This design is based on safety considerations, and even vehicles with a one-touch start function cannot lock the doors without turning off the engine. When a car remains parked in the same position for an extended period, the accumulation of exhaust emissions may enter the vehicle through the air intake. Since cars are not completely airtight, even activating the internal air circulation cannot prevent this. If someone is locked inside the car, it could lead to serious consequences.
