With the rapid spread of automobiles, automobile-related products have also been developed in various ways, and countless kinds of automobile remote controllers, global positioning systems, and liquid crystal televisions for automobiles have become numerous.

Among them, the remote controller as a controller for remotely controlling relatively simple functions such as opening a car door or starting a car can be started with the car door remotely. It saves the trouble of inserting a car key in a box), so it is used as a beneficial tool for the user of the car.

However, these remote controls are compact and easy to carry and carry in a user's bag or pocket.There is a risk of loss or theft, and the remote control can be operated at a distance of up to 300 ~ 400m. If acquired by a learner, there is a big problem that the car is likely to be stolen.

In order to overcome the shortcomings of the remote control, the user information is entered into a security card such as a smart card, and installed in a car to communicate with the security card to read the user information, and then confirm whether the user is a legitimate user. An automatic car door unlocking device has been developed that automatically unlocks the car.

The above-mentioned automatic car door unlocking device does not need to operate a car key or remote control because the car door is automatically unlocked if the distance between the user who has a security card and the automatic car door unlocking device installed in the car is within a recognition distance that can communicate.
