What to Do When the Car Key Can't Unlock the Door?

[AndrewRose]

The reason why the car key cannot unlock the door is that the remote key is out of battery, the car battery is dead, or there is strong signal interference around. You can use the hidden mechanical key inside the remote key to open the door. If the mechanical key also fails to unlock the door, it indicates a door lock malfunction. If the car key is out of battery, simply replace the key battery. If the issue is with the door, it needs to be repaired at a service center. Methods for door maintenance: Regular lubrication: The door is the most frequently used part, especially if opened or closed incorrectly or if passengers do not handle it properly, which can easily cause damage. Therefore, always keep the door hinges lubricated to reduce wear. The correct way to open and close the door is to fully open or close the window glass, which helps prevent door damage. Use of protectants and sealing strips: The door also serves to block outside noise and prevent water leakage. If aging or damage occurs, it can easily lead to water leakage and noticeable noise. Therefore, during door maintenance, regularly clean dust with a brush and apply a high-penetration protectant to prevent sealing strip aging, achieving better maintenance results.
