Can the car still be driven normally when the car key is away from the vehicle?

Keyless start system is a two-way communication system, the host is in the car, in the cockpit, door handle, trunk these places will be arranged some antennas, the driver with the car key into the antenna signal range after the host can be connected with the car key, verify the legitimacy of the car key, if it is a legal key can be allowed to open the corresponding door, start, open the trunk and other operations. The coverage of these antennas is very narrow, and it is generally ineffective one meter away from the body, which is for safety reasons, otherwise it is easy to be used by bad actors if you lock the car and go out far and still sense the car key.

When the engine is started, even if the car key is taken away, the engine will not turn off, which is also for safety reasons, because the car is determined by the antenna in the cockpit to determine whether the car key exists, we can imagine such a situation: the car key suddenly runs out of power while driving, at this time if the system turns off, it will cause serious consequences, so even if the car key is not in the car after the engine starts, the engine will still not turn off, at this time the car can drive normally, Therefore, when the keyless start car does not turn off, even if you throw away the key, others can still drive away.

This is all my experiment, I don't know what the situation of other cars is, but Magotan can't drive away without a key after ignition, except for one case, that is, other starting components are installed. My car was later installed Loulan start, can be controlled by mobile phone, I control the car at home to start the hot car, to the garage even with the key can not open the door, only with the mobile phone open, at this time the car key temporarily lost control, without the key can also drive away, but after the parking and then start and then need the key, or need a mobile phone.

Keyless start can only control the start of the vehicle, not the ignition. If after the car is started, even if you take the key to the moon, the car will not turn off and can still continue to drive, and the instrument will only indicate that the key is not in the car.

I remember that one of my colleague Lao Li's earliest cars was keyless-started, and keyless start was only available in high-end cars at that time, and there were almost no models below 200,000 yuan. Once, in order to show off himself, Lao Li bragged and said: My car can be started without a key, and then I then said that I can drive your car without a key, and I don't believe that after you start, I will drive it to you.

Lao Li just didn't believe it, and then many colleagues went downstairs to witness the miracle, Lao Li started the car with confidence, deliberately ran far away, for fear that the vehicle could receive the signal, it turned out that Lao Li lost, as long as the keyless vehicle starts, there is no key can be driven, but it can not be started after the ignition is turned off.

When the car key leaves the vehicle, it must not start.

If the engine is running and someone gets out of the car and takes the car keys away, as long as the engine is not turned off, the car can still continue to drive. However, most of the one-button start vehicle dashboard will prompt the smart key to stay away, some are bright red key lights, and some are beep prompts. If the driver pays a little attention to the dashboard, it can generally be noticed at the first time.

Hello, for those button-start vehicles, the car key leaves the vehicle, as long as the car is not turned off at the beginning, if it is open, it can be driven all the time, but it can not be turned off, unless the fuel is exhausted, I hope mine can help you, thank you!

Yes.

Automotive professionals said: many vehicles with a one-button start function, when the smart key leaves the car, it will only show on the screen that the smart key is not in the car, but the car can still continue to be used, but once the engine is turned off, it cannot be started again.

Vehicles with a key to start, generally when the smart key leaves the car, there will be a prompt sound, and there will also be a display on the screen, but some car owners think that the vehicle can be started and do not pay much attention, in fact, this is not right, in case of the next destination, after the vehicle is extinguished, it can no longer be started, and it needs to be sent to the smart key to start again. Therefore, the owners of these vehicles should carefully check whether the smart key is left in the car to avoid unnecessary trouble.

If the car is on fire and the car keys are not in the car, the car can be driven away, but the car is turned off, and there is no way to reduce the fire for a while.

You can drive away, but you can't start it again after the ignition is turned off. If the key is not in the sensing range, or if there is no signal, the instrument cluster will prompt, but it will not automatically turn off. That is, as long as the key is not in the car after starting, as long as the engine is not turned off, the vehicle can drive normally, but the instrument will remind the key to warn.

Hope it helps.

There are two situations in which you can drive away without a car key: you can drive away, and you can't drive away.

1. You can drive awayThe first situation is that you can't drive away, but there is a prerequisite for the vehicle to have a remote start function, at this time, the owner can use the mobile phone APP software to unlock the vehicle, and then let the vehicle drive normally.

2. Can't drive awayThe second case is that it can be driven away, such as the yard is carrying the fruit vehicle can only be unlocked with a mechanical key, in this case, the vehicle cannot be started without a key. For vehicles with one-button start, when it is successfully started, it should be noted that even if the smart key is not on the vehicle, it can still continue to drive. However, after the vehicle is turned off, the vehicle cannot start normally without the smart key.

Precautions for the use of car keys:1. After the car is on fire, release the key immediately, and the engine strip will be damaged if you keep screwing it.

2. Don't hang the key and the jewelry together, the collision with the jewelry will make the keyhole gap gradually larger.

3. Do not expose the key to a high temperature environment or contact with liquids.

As long as the fire is not turned off and there is still oil, it can be turned on all the time.

The keyless start system is effective when the car starts, and will identify whether it is the real owner according to the presence of the hyptar key, and only the key can be started with a key when it is nearby, but when the car is started, the keyless start system will not recognize the key, and only need to have oil to go all the way.

Therefore, after the keyless start, if the car has been driven forward without turning off, it can be driven all the time, and it can be driven until there is no oil or the engine is turned off, and when the engine is turned off, it will start to recognize the key again if it wants to start again.

How it works. The system uses state-of-the-art radio frequency identification.

RFID) technology, through the chip in the smart card carried by the car owner, the door lock is automatically opened and opened, that is to say, when the driver approaches the vehicle at a certain distance, the door lock will automatically open and lift the anti-theft; When the driver leaves the vehicle, the door lock is automatically locked and enters the anti-theft state.

Generally, vehicles equipped with keyless entry systems have inductive buttons on the door handles, as well as keyholes, so that the owner can still open the door in the normal way when the smart card is damaged or the battery is out.

When the owner enters the car, the detection system in the car will immediately recognize your smart card, and the computer in the car will enter the working state after confirmation, and then you only need to press the start button (or knob) in the car lightly or stupidly, and the vehicle can be started normally. This means that the system can be sure that the driver will be correctly identified in all circumstances, both inside and outside the vehicle.

OK.

Put the key outside the car at a distance of one or two meters without response, but after the distance is far away, there will be a reminder immediately, the smart key is not in the car, although there is a reminder at this time, but the car can still drive away.

As soon as the car starts, the prompt will run, but as soon as the brakes are pressed, the prompt will come out as soon as the car stops, so as long as you stop and look at the dashboard, you can find that the key is not there.

Note: If you really want to drive the car out but the key is left at home, and you want to drive the car back smoothly, you can't turn off the engine in the middle of the way, and you run out of gas, then drive to refuel and wait until the car is back. Once the ignition is turned off, it means that the car will not start, and you will have to call for a tow truck or someone will need to send the keys over.

If you go out by car, especially if you need to go to the field for a long time, it is recommended to bring the spare key, but the main key and the spare key should be separated, so that in case a key is lost outside or something goes wrong, there is a spare key.

I can open, also according to different cars, my own experience: BMW 7 Series, take the key after starting, can open, but after parking and turning off the door, it will automatically lock. If you open the door again, you can't open it, you must have a key; Mercedes-Benz E series, take the key after starting, can open, but after driving a certain distance, the car prompts to stay away from the key, alarm, the door is automatically locked, and the door cannot be opened in the car.

If you start the car and take away the car keys, can the people in the car still drive the car away, you know?

With the continuous improvement of people's living standards, now basically every family has their own car, and many car owners will encounter such a troublesome thing, that is, when the vehicle is started, the key of the car is envious and does not carry a few keys, and for this case, the car can not continue to drive, because once the car is turned off, because the car does not have a key then it can not be started again, and the car key needs to be obtained before continuing to start the vehicle.

Now many models are keyless start, for this keyless start has a characteristic, that is, when the car key and the car have a certain distance, the car because there is no key so start the vehicle again will not work, and when the vehicle starts, if the owner finds that the car key is not on the body, then do not drive the car first, be sure to get the car key back before continuing to drive, but for this situation is often caused by the driver's negligence, if the car has been on the road, At this time, the owner of the car must not turn off the car, because at this time, the car will not be able to start again, and the owner must drive the car to the place where the key is taken back to get the key to turn off. <>

2. Do not turn off the engine while the car is on the road.

If you forget to bring the car key, and the car has been driven out, at this time the car key and the car have a certain distance, so at this time the car owner must not turn off the car, because after the car is turned off, the vehicle can not be started again, and the only thing the owner does is to drive the car back to the original place, take the car key back and then park. <>

3. Summary. In general, before the car starts, the owner must check his car key, often this forgets to bring the key and ignite the car is generally a key to start the model, because as long as the owner hangs the key next to him or put it in the car, the car can be ignited, for this case, the key is not brought on the body or the car must not continue to drive the car, otherwise the second ignition of the hail car will not be successful, which greatly increases the cost of the owner's car. <>

If it is an old-fashioned car with more accessories, then when the key is pulled out, the car can still continue to drive, for the current cover sail civilian car, after the car starts, the key can not be pulled out at all, and for the car with a key to start, there is no need for the key, and as long as the state of starting is maintained, the attack vehicle can continue to drive and will not turn off.

Of course, it cannot be continued to open, once the key is pulled out of the lock cylinder of the car, then the power supply of the car will be disconnected.

Can't keep opening. When the key leaves the car, the car does not start.

The keyless start system is in effect when the car is started, and will identify the real owner based on the presence of the key. One-button start is only possible when the car is nearby, but the keyless start system is not available when the car is started.

Re-identify, just refuel, and you can go all the way. Therefore, if the car does not turn off and drives forward, it can continue to drive until there is no gas or the engine goes out. The key will be recognized again when you want to start it again after the ignition is turned off.

The system uses state-of-the-art radio frequency identification (RFID) technology to automatically open and close the door lock through the chip of the smart card that the owner carries with him/her. That is to say, when the driver approaches the vehicle and takes Sun Ding, the door lock will automatically open and the anti-theft chain will be lifted. When the driver leaves the vehicle, the door lock is automatically locked and enters the anti-theft state.

Generally, vehicles equipped with this system have buttons on the handlebars, and at the same time, there are also empty keys to prevent the owner from breaking the smart card or running out of power, and the owner can still open the door in the normal way. When the owner enters the car, the detection system will immediately recognize your smart card, and the computer in the car will enter the working state after confirmation.

No. It turned out that unlocking the car door remotely from a mobile phone was basically impossible. So how to deal with the car key locked in the car, or forget to bring the car key, some car spare keys are mechanical keys, you can use the spare key with a key out, the car key with double-sided tape.

Glued to the front and rear bumpers.

Remember to stick it tightly!

Seek off-site assistance. If the owner can neither enter through the trunk to get the key, nor can he unlock the lock through the app, then need help from the outside! There are many car unlocking service companies, and you can come and solve the problem by calling their ** directly.
