As automotive technology becomes more and more intelligent, there are many keyless starting cars in the modern car market. The smart key can switch the car on and off, which raises the question, that is, if the owner leaves with the smart key of the car, can others drive away the car? If it can be opened, what will be the consequences?
The answer to this question depends on the programs written by the car manufacturer for the car. The first case is that the car does not turn off when it is parked and hangs on the D gear, the owner of the car with the smart key away from the car, and then anyone can drive away from the car. But in this process, the car can not be turned off halfway, nor can it be hung up P gear, otherwise the car cannot be started before using the smart key.
This is because keyless cars use RFID technology, and when the car is started and used, there is a two-way password verification between the car and the smart key. If the car's program is that when the car does not receive the next command from the smart key, it will remain in its current state, then as long as the car does not deliberately turn off, it will remain in the current state.
Therefore, the owner of the car leaves with the key does not cause the car to stop immediately, naturally anyone can drive away the car that has not been turned off. When the car is turned off, without the next command of the smart key, it will remain in the flameout state and can no longer be used.
Of course, if this happens, there may be more serious consequences. After all, the car can not stop and turn off the ignition during the driving process, and once it stops and turns off, it cannot be ignited again, which means that the car cannot stop and refuel in the middle. If there is no oil in the wilderness, I am afraid that I can only call a trailer to help me deal with it, and then it will be a lot of money.
The second case is that the car automatically turns off. Some car programs are quite "intelligent", and the computer equipped with the car will check the status of the car and intervene in the control of the car in some states. For example, when the car is put into the P gear, if the car has not been turned off, then in ten minutes or half an hour, the computer equipped with the car will detect that the car is not running, so it will automatically turn off. In this case, a person without a smart key cannot drive the car away.
The last case is that the car will not turn off anyway, as long as it is not turned off with a smart key, even if the car is hung in P gear, the car will not stop. The procedure of this car is mainly for the safety of children. When the car is parked under the hot sun, the temperature inside the car may reach 60 to 70 degrees Celsius, which is entirely likely to pose a life-threatening to the children in the car.
If it is an adult, it is better to say, if it is a child, it is possible that the child will be forgotten by the parents in the car that is turned off, and finally lead to the child being heated to death. In order to avoid this, some keyless cars have written relevant programs. As long as the car does not use the smart key to deliberately turn off, then even if the car hangs on the P gear for a day, the car will not stop, the children in the car can open the door at any time and walk out of the car, and others can also drive away the car anytime and anywhere. Of course, this kind of car is inferior in anti-theft.
