The development history of car keys

The original car key is no different from our ordinary door key, and has no function. Insert the key into the lock hole and turn the key to start and stop the fire. Until now, the secondary key of some low-end cars is still this way. This kind of key has basically no advantages except that it does not need to change the battery, it is inconvenient to carry, and it is easy to be broken or lost. With the development of society, later car keys added a chip, which could communicate with the vehicle. If it were not for the original car key, the engine could not be started. At the same time, the lock and unlock buttons were added to the key shell. Yes, it facilitates daily operations. Later, due to the inconvenience of carrying the key, the folding key was invented. The key is folded when not in use, which is convenient to carry and prevents the key from being broken. When in use, the key is automatically ejected by pressing the button on the key shell. With the continuous development of automotive electronic technology, since the keyless entry and one-key start functions, folding keys have gradually become useless. Vehicles with keyless entry and one-key start functions go from unlocking and getting on the car to starting the vehicle. There is no need to use the key in the whole process from turning off the flame to locking the car. Just put the key in the sensing area. This is also the mainstream practice of most car companies at present. Therefore, the car keys now have different shapes and more and more functions. The more, it is no longer limited to unlocking the door, such as opening the trunk, remote starting, etc., and more advanced is a series of operations such as vehicle calling and controlling the air-conditioned seats in the car. That is to say, you only need to put the key on your body, you don't need to take it out at all.
