Some people say that for vehicles with keyless start, as long as the vehicle is in the start state, no matter how far the key is taken out, it will not affect the driving of the vehicle. Even if you take the car key to the United States, it will not affect driving as long as the car has not been turned off when the key leaves the car.

    Logically speaking, the operation of automatically turning off the oil and automatically turning off the engine without detecting the key is very simple from a technical point of view, but why don't car companies design like this?

    In fact, this is mainly considered from the perspective of driving safety, because the remote key is mainly obtained and perceived based on the wireless signal. However, due to the interference of the wireless signal, it is likely that the key will not be found. At this time, sudden flameout is very dangerous.

    For the existing models, whether the car can run normally when the car key is not available can be divided into two situations.

    The first situation is that after parking, the vehicle does not turn off, and the owner leaves with the smart key. Once the smart key is more than 3 meters away, the low-frequency signal receiver in the vehicle will not receive the signal of the smart key.

    At this time, the trip computer will give a fault prompt and display a prompt such as "smart key not detected" on the vehicle instrument panel. After that, if the trip computer does not preset other commands, the vehicle will remain idle until the fuel is exhausted.

    In the second case, the vehicle will shut down after the vehicle key leaves the vehicle, but this is also conditional. First, after the vehicle is started, it does not drive in D gear. At this time, the continuous working time of the engine has exceeded a certain time (according to the settings of various model manufacturers, the minimum is 15 minutes and the maximum is half an hour). After this time, the engine will automatically start the protection program and the vehicle will shut down automatically.

    Of course, this situation is mainly aimed at some new models in recent years, especially many models after 2020 have this function.

    For cars with keyless start models, when the car is still starting, the waiting owner leaves with the car key. Can others drive away.

    In fact, the key issue is whether the car door has automatic locking function. If there is a car with automatic locking function, others will not drive away. If there is no car with automatic locking function, others can drive away.

    In general, there will be a sound or light prompt when the car is not locked, and listening to the sound of locking the car is a routine action for most car owners, and the prompt will also alert the car owners. Therefore, as long as it is not the kind of careless Mahal owner, it is good to pay a little attention at ordinary times and don't worry too much about this problem.

    I have to admit that the rich vehicle configuration does bring great convenience to our car life, but at the same time, we should also pay attention to the skills and norms of use to avoid such an embarrassing situation and affect the car life. Pay attention to my previous articles and hope to help your car life.
