Can a Vehicle Be Locked Without Turning Off the Engine?

It is not possible to lock a vehicle without turning off the engine. Even for certain models that allow locking the doors while the engine is running, the engine will automatically shut off after locking. This is primarily for safety considerations. Even vehicles equipped with a one-touch start function cannot have their doors locked without turning off the engine. Below are some tips to prevent forgetting to turn off the engine when exiting the vehicle: 1. Check the RPM gauge and display screen: Before exiting, check if the display screen has turned off and gone black, and if the RPM gauge reads zero. This is a conventional method and should become a habit. However, sometimes distractions like having multiple passengers, answering phone calls, or being in a hurry to exit can lead to overlooking this habit. 2. Steering wheel elevation: When setting the steering wheel position, avoid setting it at the highest position. This way, when parking and turning off the engine, the steering wheel will rise slightly. This subtle change may not always be noticeable but serves as a weak reminder. 3. Enable daytime running lights: In the lighting settings, turn on the daytime running lights. This method is quite effective—after locking the doors, check if the daytime running lights are off, which confirms the engine is definitely off. However, some people may find daytime running lights too conspicuous and prefer not to use them regularly, making this method unusable for them.

I've been running an auto repair shop for years, and customers often ask this question. Yes, vehicles can be locked without turning off the engine, especially common in modern models. They're designed to allow you to lock the doors with the remote key while the engine keeps running, which is convenient for situations like warming up the car in winter while stepping out to shop. But this practice is highly risky! Aside from increased fuel consumption and wear, the main issue is the significant safety hazard. If the car is left running and locked, a thief could easily break the window, get in, and drive away instantly. I've encountered such cases before, where car owners suffered heavy losses. Moreover, in enclosed areas like garages, engine exhaust can accumulate carbon monoxide, which can be deadly. I strongly recommend always developing the habit of turning off the engine before locking the car—it's both safer and more environmentally friendly. If you must lock the car with the engine running occasionally, ensure the key isn't left inside and that the parking area is open and well-monitored.

As a car owner who drives daily, I've tried locking the car without turning off the engine a few times. Most modern cars can do this because the remote key or smart sensing system allows you to lock the doors from outside. The engine keeps running, and it's quite comfortable with the air conditioning or heating on inside. But I really don't recommend doing this! The risks are too high. I remember once locking the car in a parking lot to buy coffee, and I was nervous the whole time, worried about theft or accidents. It's even more dangerous with children or pets inside, as the air gets stuffy in a confined space. From a mechanical perspective, prolonged engine idling leads to increased carbon buildup and higher maintenance costs. It's best to develop the good habit of turning off the engine before locking the car—safety first. If you must do this, choose a crowded area for a brief stay.

With over a decade of driving experience, I've learned that locking the car without turning off the engine is absolutely to be avoided. Although modern systems support remote locking with the engine running, the consequences can be severe. I once witnessed a neighbor's car being easily stolen when left running with the doors locked, and it was never recovered. Additionally, locking the car with the engine running increases fuel consumption and noise pollution. Always remember to keep your keys on your person; otherwise, if the system malfunctions and the doors aren't locked, you could face serious trouble.
