1, crank key, the earliest steam car is through the steam to push the internal piston up and down movement, without the need for tangible objects or keys. With the technological innovation, the hand-cranked engine appeared, and then the prototype of our so-called car key - the crank was born.
2, mechanical keys, electronic ignition system after the popularization of the car key prototype gradually appeared. The traditional key was introduced, and it could become a mechanical key or blade key, which seemed to be no different from our current door lock key, and the function of the car key was quite simple at that time, with only two functions of opening and closing the door and starting the engine.
3, the chip key, because the traditional key as long as the same tooth shape can open the door, anti-theft function is very limited, in order to make up for this very poor security defects, the chip key was born. At this time also formed a car a key situation, even if the same tooth shape of the key can still open the door to start the engine, but can not be maintained for a long time, can not drive the car away.
4, all-in-one key, key + remote control combination functionality is satisfied, but there is a new problem, inconvenient to carry, so this contributed to the emergence of the all-in-one remote key. One-piece remote key is combined into one, compact and simple shape, while the mechanical key can be folded, one-piece remote key is also our most common type of car keys.
5, Bluetooth smart key, relying on the car network and Bluetooth technology, car manufacturers to cell phone mobile applications to activate our own vehicle keys. After the driver approaches the vehicle at a certain distance, the cell phone key system will automatically identify the location of the cell phone key and unlock it. When the owner closes all doors and leaves the phone, the phone key system will automatically detect the phone key and lock the car.
Nowadays, all major car companies have released Bluetooth car key models, such as Tesla, Ideal ONE, Xiaopeng car, Changan CS75, etc. The market prospect is broad. Innovative Micro independently developed and produced Bluetooth module, the module can come with its own transmission program (master/slave), customers can add Bluetooth function without Bluetooth development, also can support the secondary development of customers, with low power consumption, anti-interference, small size, long distance, low cost, etc., and through BQB, SRRC, FCC, CE, RoHS, TELEC and other domestic and foreign authoritative certification, can be widely used in all kinds of electronic devices. In the future, there will be more new energy vehicles equipped with Bluetooth car keys, which will also promote the diversified application and development of Bluetooth modules to a certain extent.
