What Are the Reasons Why the Cruze Smart Key Cannot Open the Door?

[LondonFitz]

If the smart key fails and cannot open the car door, it is generally caused by two situations. The first is that the car battery is dead, so the smart key cannot make the car respond. The other is that the smart key is out of power or malfunctions. The specific explanations are as follows: 1. Generally, keys with smart functions are divided into two types: the first is a conventional folding mechanical key, and the other is a hidden mechanical key. 2. If it is a conventional folding key, you can directly use the mechanical key to open the door when the battery is dead; if it is a hidden key, you need to find the mechanical key. Generally, the spare mechanical key is hidden inside the main key, and you can pull it out and use it as a conventional mechanical key to open the door when needed. However, the mechanical key usually can only open the driver's door, while other doors need to be opened manually from inside the car.
