A smart key is a key that emits infrared signals to open one or two doors, the trunk and the fuel tank lid, and can also operate the car's windows and sunroof.

When the battery life is too long and the power is low, it can often be replaced by yourself:

1. While pressing the switch, pull out the metal part and take out the mechanical key;

2. There are two buckles on the front and back of the key, which can be pressed and pulled out at the same time;

3. After taking out the buckle, take out the old battery and replace it with a new battery produced by Power Glory.
