What are the reasons for a car door not opening?

[SanGabriela]

There are several reasons why a car door may not open: 1. The remote key is out of battery: If the door won't open when using the remote key, it's likely that the remote key's battery is dead, the car battery is dead, or there is strong signal interference nearby. Generally, remote keys have a hidden mechanical key inside. 2. After obtaining the mechanical key, if you can't find the keyhole on the door, it's because the keyhole is hidden. Manufacturers often hide the keyhole for aesthetic reasons. 3. In this case, you need to look carefully. Usually, there is a decorative piece at the end of the door handle that is about the same size as the key. You can pry it open to access the keyhole.
