How Many Car Keys Are There?

[MadisonFitz]

When purchasing a car, two keys are provided: one for regular use and one as a spare. Introduction to Mechanical Keys: Mechanical keys are the most common type of car keys. The door locks that match mechanical keys are generally similar to home door locks, requiring the key to be inserted into the keyhole and turned to unlock or lock. The drawback is that they cannot remotely start the vehicle and may not meet certain specific scenarios. Currently, they have largely been replaced by remote keys. Introduction to Remote Keys: Remote keys typically use weak radio waves emitted by themselves to control the opening and closing of doors. The advantage is that they can remotely start the vehicle, making them more convenient to use compared to mechanical keys. In addition to door control, they can also remotely operate windows, trunk doors, etc. Furthermore, remote keys have low power consumption and strong battery life.
