In fact, in addition to the dilemma mentioned above, there is another situation that is very annoying: in some emergency situations, the driver often spends a lot of time due to mental stress or unfamiliarity with the vehicle ignition key socket Only then can the vehicle key be inserted into the key opening to start the vehicle. So the keyless start system came into being, and its purpose is to avoid the trouble of inserting the key when people start the car.
Most keyless entry systems include a keyless start function, and only a few models have only a keyless entry function, but no keyless start. Therefore, we will combine the two into one, collectively referred to as the smart key system. If we encounter a single keyless entry or keyless start system, we will specifically mention it. Let ’s let car exploration give you a detailed introduction to this convenient , Humanized intelligent key system.
Keyless Entry System
Smart card for keyless entry system of Nissan Teana
Using the most advanced RFID (radio frequency identification) technology, the door lock is automatically opened and closed through the chip in the smart card carried by the owner, which means that when you approach the vehicle a certain distance, the door lock will automatically open and release the anti-theft; when you When leaving the vehicle, the door lock will automatically lock and enter the anti-theft state. Vehicles equipped with a keyless entry system generally have a sensor button on the door handle and a keyhole to prevent the smart card from damaging or running out of power. The owner can still open the door in the normal way.
The sensor button on the door handle of the car, the keyhole is opened in the normal way when the smart card is damaged or there is no power
Keyless Start System
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. At this time, you only need to gently press the start button (or knob) in the car , You can start the vehicle normally. That is to say, whether in the car or outside the car, it can ensure that the system can correctly identify the driver under any circumstances.
Buttonless keyless start Knobless keyless start
It can be divided into two types according to the method of use: one is the button type, the ignition button is located within the reach of the center console, so it is also called "one-key start", such as BMW, Mercedes-Benz, etc .; the other is the knob type, It is usually located at the original key socket, but without inserting the car key, you can directly turn the knob to start, such as Nissan and Mazda.
In addition to being convenient, the smart key system is also very helpful for vehicle anti-theft and security:
1. When you start the vehicle and start the vehicle, the first foot brakes and the four doors will automatically lock. When the city is stuck in traffic or walking alone at night, it can prevent accidents such as carrying bags, so it is foolproof.
2. When you enter the vehicle, the vehicle can identify the real owner. If the owner is not in the vehicle, the vehicle will not start and will immediately call the police. 3. The complete cryptographic identity recognizer (electronic key) encryption system cannot be copied. The fourth-generation radio frequency identification technology (RFID) chip is used, which fully meets the requirement of being unable to copy. The existing chip-type anti-theft devices on the market and the original car configuration chip anti-theft devices are basically second-generation or third-generation chips, and have not completely solved the problem of being copied. 4. Anti-theft of the whole vehicle-By locking the circuit, oil circuit and starting three points, when the anti-theft device is illegally removed, the vehicle still cannot start. 5. No false alarms-the product uses the most advanced anti-collision technology, which greatly enhances the reliability of the system. 6. Automatically close the window after locking the car. When the owner gets out of the car, if he forgets to close the window, there is no need to restart the engine and close the window. The vehicle safety system will automatically raise the window, greatly improving the safety of the car. Level, no accidents such as forgetting to close the window and raining, the smart key system allows you not to worry about forgetting to lock the door every time you leave the vehicle.
Through the above introduction, I believe you have a more comprehensive understanding of the keyless entry and keyless startup of the smart key system. These two functions based on smart chip technology and RFID (radio frequency identification) technology do indeed use this kind of car for us. Traffic transportation tools bring great convenience. At present, many models sold on the domestic automobile market are also equipped with similar smart key systems, ranging from expensive high-end cars to cheap and compact family cars. Let's take a closer look at which models of domestic cars are equipped with an intelligent key system and their respective characteristics.

Smart keys for Nissan Tiida and Yida
In this class of domestic cars, only Dongfeng Nissan's Tiida and Yida are equipped with an intelligent key system, of which only the highly configured Tiida 1.6GE automatic type, 1.6GS automatic type and Yida 1.6JE automatic type, 1.6JS automatic type are equipped with intelligent standard The key system has a price range of 139,800-15,200 yuan. They are equipped with an intelligent key system that has both keyless entry and keyless start functions. They use a knobless keyless start method. It can be said that it is possible to equip models with a price of about 150,000 yuan with an intelligent key system. Although it is not particularly advanced or luxurious equipment, it is convenient to use. It is worth advocating only in terms of humanity.
Compact car
Dongfeng Nissan Xuanyi is famous for its high configuration, and is equipped with an intelligent key system and CVT gearbox.
This class of models includes Dongfeng Daily Sylphy and FAW Toyota Corolla, which has just been launched recently, are equipped with an intelligent keyless system. Among them, Sylphy 2.0XL Technology Edition and 2.0XV Premier Edition, and Corolla 1.8 Preminu automatic model are equipped with an intelligent key system. They also have both keyless entry and keyless start functions, but the keyless start methods of the two are not the same. Xuanyi uses a knob type, while Corolla uses a button type. Although the final result of the two makes driving a car more convenient, it seems that to many people, the push-button start is more advanced and fashionable, and it is cooler. In fact, it is also more convenient to use the push button. At least I am Think so.
The keyless start of the highest version of FAW Toyota Corolla uses a button type, but it is equipped with a 4-speed automatic transmission
Small MPV
Dongfeng Nissan Junyi is the only domestic MPV model equipped with an intelligent key system
Dongfeng Nissan Junyi is the only MPV model equipped with a smart key. There are three models: 1.8XL comfort, 1.8XL fashion version and 1.8XV distinguished type. The price is between 15.68-16.23 million. The model has the same smart key system. Junyi is a small MPV model of Dongfeng Nissan with the main purpose of comfortable life and free space. It can be equipped with an intelligent if system, which is particularly prominent in its comfortable and free features.
Mid-level car
Nissan sedan is the big winner of smart key configuration, the first 4 levels are equipped with models
The mid-level sedan is the most competitive segment in the domestic auto market. The battle between the Honda Accord and Toyota Camry has continued to the top, but neither of the first two is equipped with an intelligent key system, which is regrettable. This level of Dongfeng Nissan Teana and Mazda 6 have models equipped with a smart key system as standard. The smart key system of these two configurations uses a smart card design + knobless keyless start.
Mazda 6 smart card with smart key system
Among them, Mazda 6 includes 2.3 flagship model, Mazda 6 coupe automatic model and Mazda 6 Wagon three models are equipped with intelligent key system, and Teana is the standard intelligent key system of the whole system. In the first four levels of cars, all Nissan brand models are equipped with an intelligent keyless system. This is not what we are advertising. The fact is that Nissan has always attached great importance to the humanized configuration of its products, and increased it by increasing the technical content of the configuration. In the overall competition, Nissan models have always been good at.
Medium and large cars
The keyless start button of the Audi A6L is located on the left side of the shift lever, which is special
The start button of the crown and red flag HQ3 The keyless start button of SLS Savi is square
Most models of this level belong to high-end cars, so there are many models equipped with intelligent keyless system, including: Audi A6 (quote; picture) L, Mercedes-Benz E (quote; picture) class, Cadillac SLS, Crown, Hongqi HQ3 and For the upcoming Magotan series, their smart key systems also have a keyless entry function, and all use a button-type "one-key start" method.
Magotan's smart key system can be accessed without a key, but the smart key must be inserted into the start port before starting
It should be mentioned here that the smart key equipped with the Volkswagen Magotan and Mercedes-Benz E-Class must be inserted into the start port on the center console when it is started, and the key can be pressed to start, so it is generally considered that this is not a real Key start system. For the same reason, BMW 3 Series and 5 Series cars equipped with a button-type "one-key start" early also need to insert the key to "one-key start", and BMW's remote control key does not have a keyless entry function, so BMW Brand models are not included in the smart key system.
Models with smart key system for domestic vehicles
It can be seen from the table above that the main equipment equipped with the intelligent keyless system is mainly medium and large-scale high-end cars, but it has also penetrated into the ranks of small cars. Nissan models account for the vast majority of the lower three levels. This shows that Nissan has very high requirements on the humanization and intelligence of its products, so as to increase the high-end configuration of cars at the same level to enhance product competitiveness. At the same time, it can also be seen that the two latest models unveiled in China, Corolla and Magotan, also have models equipped with smart key systems, which shows that adding more high-tech to enrich the configuration is one of the ways for new products to stand on the domestic car market.
The times are evolving, technology is advancing, and more and more high-tech and new gadgets have entered contemporary automotive equipment. These things were designed to make people more convenient and safer when using cars. Therefore, humanized equipment such as intelligent keyless systems will soon become the standard equipment for cars at all levels.
