The history of car keys has not been older than I thought. There was no key concept when the car first appeared 130 years ago. In 1886, the Mercedes-Benz Motorwagen, patented for the first time in the world, was powered by a revolving flywheel behind the bodywork.
Long ago, in the rural area to start a tiller boots, you can think of turning the tool in the form of a starter.
In 1949, Chrysler introduced a "turnkey starter" car key that turns the key to open the car door and start the car as if it were a key.
The turnkey starter car key has been used for nearly 50 years due to its low manufacturing cost and ease of making it. But it was easy to duplicate and was easily exposed to theft. There was also a movie scene where a key was put on a soap or candle to steal a car and then a duplicate key was made to match the shape.
Obviously, the insurance industry, which had to pay for theft insurance, hated it. At the request of the insurance industry, which suffered losses due to car theft, the automobile parts industry introduced a button - type wireless key in 1994, using the immobilizer technology. In the case of a vehicle equipped with an immobilizer, a unique password was required to open the door and start the vehicle.
The wireless key opened the door wirelessly, but in order to start it, the key was turned on and turned on. It is still a key figure.
The key figure began to disappear in 1998 when the PASE (Passive Start and Entry) smart key, which opens and fires without a key through the radio frequency, has disappeared.
The smart key has evolved in terms of visual and tactile aspects. At first, the appearance was made of plastic material, and the shape and texture were rough. However, in order to appeal to demanding consumers, they pursued a smaller, more stylish look with stainless steel, matte aluminum, glass, leather and ceramics.
Resin Transfer Molding (RTM), which was applied to semiconductor manufacturing, contributed to the key diet. At that time most of the car keys were injection molded with `thermoplastic resin`. To protect the electronic components inside the key, the thickness had to exceed 6mm.
However, by using RTM method using special epoxy compound, thickness of 2mm or more can be reduced, and the shape can be precisely and delicately designed.
The smart key met with NFC (Near Field Communication) and became one with the smart phone. The NFC smart key is to install applications on smart phones and use them as vehicle smart keys. It is a digital key.
NFC is a non-contact, near-field wireless communication technology that enables bidirectional data transmission and reception between terminals within 10cm distance. In the IT field, it is widely used for electronic payment or financial transactions through transportation cards, credit cards and membership cards. However, in the automotive sector, technology applications are rare.
Among the domestic auto parts companies, Hyundai Mobis is the only company to complete this technology. Only a handful of companies have acquired relevant technology globally. Hyundai Mobis aims to mass-produce next year.
You do not need to take your car keys with NFC smart keys. Usage is also simple. When you go to the car and take out your mobile phone, run the app and put it on the door handle of the vehicle, the door will be unlocked with the sound of `pic 'like pressing the smart key button.
When you are in the driver's seat, place the smartphone on the separately installed wireless charger pad and press the START button. Inside the car handle and wireless charging pad, there is an antenna to receive the NFC signal, so communication between the vehicle and the smartphone is possible.
NFC smart keys make vehicle sharing easy. The owner of the vehicle may grant key use rights to a third party, such as a spouse. You can use this feature if you use your car publicly or inevitably if your car is being used by someone else.
If you need permission, you can install the relevant app on your smartphone with the permission of the car owner and go through the authentication process. You do not need to meet someone to share with you after you get your keys.
The owner of the vehicle can control the usage rights even if the third party is given the right to use the smart key. You can set the car to use only on certain days and time zones, or you can open the door but not start it.
However, the NFC smart key is not universal. It 's because of the digital duplication key called `hacking. To prevent hacking, Hyundai Mobis has developed an authentication controller that employs the latest data encryption and authentication technologies.
The role of the controller is to highly encrypt the vehicle and smartphone information and accurately verify the match between the vehicle and the phone owner. It is a countermeasure to prevent forgery, loss, and forgery of communication information.
