Teana's doors can be locked without turning off the engine. You can use the mechanical key to lock the doors. Try to use the mechanical key to lock the doors: Using the mechanical key to lock the car is more reliable, as it makes any signal jammers ineffective. If you don't mind the inconvenience, using the mechanical key more often can also save power and is even safer than using a smart key. When using the mechanical lock, make sure all doors are properly closed, and you should hear the sound of all doors locking; otherwise, the locking process hasn't been successful. Observe the vehicle's lights after locking: If you use the electronic lock, you should pay more attention to whether the vehicle is properly locked. For example, check if the lights turn on after locking or if the vehicle makes a locking sound. Remember these signals, and if you notice anything unusual compared to normal, check the surroundings for any signal interference sources.
The Altima can actually lock the doors when the engine is running, but it depends on the situation. I drive this car myself, and when the engine is on, pressing the button on the door handle inside the car easily locks the doors. However, if you've already stepped out of the car with the key still inside, using the remote to lock the doors might fail, or worse, trap the key inside—which is a big hassle. With the engine running, unburned gasoline can lead to carbon monoxide buildup, making it unsafe. I recommend turning off the engine before locking the doors or testing with a spare smart key method. Other cars like the Toyota Camry have similar designs, all aimed at preventing accidents caused by mistakes. In short, avoid such operations whenever possible—safety first.
