How long will the car turn off after taking away the one-key start key?

The car will not turn off after the one-key start key is taken away. However, if it exceeds the sensing range, the vehicle cannot be started. Once the one-key start key is used to start the vehicle, it will not send any other commands. At this time, the vehicle will not turn off due to the absence of the one-key start key unless it is manually turned off. However, if the engine shuts down midway due to incorrect operation, the vehicle cannot be restarted. If the one-key start key is separated from the vehicle by more than 10 meters, in case of an emergency during driving, the engine can be turned off by pressing the one-key start button for more than 3 seconds or pressing it three times consecutively. At this time, the power will switch to the ACC state. If the engine shuts down during driving, it can be restarted by shifting the gear lever to the N position and pressing the engine start-stop button without stepping on the brake pedal. If the engine is left idling after parking, it will cause carbon deposits on the piston valves, increasing engine wear. In severe cases, it may even affect the engine's lifespan. Therefore, it is important to check whether the car key is carried when driving to avoid inconvenience in vehicle use.
This actually happened to me once. I was driving my kid to school when I realized the key was in my wife's bag. The car kept running for about ten minutes before suddenly shutting off, with a key icon popping up on the dashboard. Most cars are designed thoughtfully—they won't shut off immediately if the key leaves the vehicle, but it depends: during normal driving, they usually keep going for 5 to 10 minutes, as manufacturers want to prevent dangerous situations from accidental operations. If you park and take the key away, some cars won't move even if you shift to D and press the gas, directly prompting a "no key detected" warning. The most awkward scenario is stalling at a red light—the honking from cars behind can drive you crazy. My advice? Don't gamble on this time window. Always check your pocket for the key before stepping out.
