Tips

In the past, most cars used mechanical keys, but now basically all have been replaced by electronic keys, and car keys will be changed to cards. After the car is replaced with an electronic key, it is very convenient to use. Just press a button to open and close the door. Many cars are also equipped with keyless entry systems. The car owner does not even need to take out the key to open the door. The car can automatically unlock just by approaching the door. Now car keys will undergo a disruptive change. Ordinary mechanical keys are becoming smarter and thinner, entering the era of cards.

The card key is about the same size as an ID card. It has a hidden mechanical key and buttons that can be used to open and close the car door.

Advantages of the card key: It feels high-end, easy to carry, and can be placed in a wallet. There is also a mechanical key inside.

Disadvantages: There are no buttons, you cannot remotely control the trunk and doors (sometimes others have to go to the trunk to get something, and you cannot open it for others), and you cannot press and hold the switch glass.
