Why can't the Hyundai Mistra detect the key?

[CameronLee]

The reason why the Hyundai Mistra cannot detect the key is due to insufficient battery power in the car key. Below are specific details about car keys: 1. Types of keys: Common types of keys on the market today include mechanical keys, remote keys, touchscreen LCD keys, and smart bracelet keys. Regardless of the type, their basic functions are to unlock the car door and start the engine. Some remote and touchscreen LCD keys can also perform functions like automatic parking and viewing vehicle information. 2. Remote keys: Remote keys allow you to unlock and lock the car door from a distance without inserting the key into the keyhole. The biggest advantage is that, whether day or night, you don't need to locate the keyhole or go through the cumbersome process of inserting the key to open the door. You can conveniently unlock (open) and lock (close) the door from a distance. Remote keys can also open the trunk and fuel tank cap from outside the car, and close the windows and retract the side mirrors when locking the car.
