Where is the spare key of a sedan usually placed?

[MacJosephine]

The spare key of a sedan is placed in a small compartment on the top of the car, which is very safe and will not fall out. The differences between the spare key and the main key: 1. Different appearance: The main key has buttons, and you only need to press the corresponding button on the key to open the door; the spare key looks like an ordinary key and needs to be inserted into the keyhole on the door to open it. 2. Different types: The main key is remote-controlled, allowing you to unlock the door and open the trunk remotely by pressing the button within the car's vicinity; the spare key is mechanical, functioning as a regular unlocking key. 3. Different performance: The main key operates wirelessly, controlling the car's unlocking function through a wireless transmitter in the key, offering powerful features; the spare key requires insertion into the keyhole to open the door.
