The reasons for the car door not opening and the key not working are: 1. The remote key is out of battery, causing the door to not open; 2. The remote control is malfunctioning; 3. The door lock mechanism itself is faulty, or the door lock cable is not working; 4. After the door is subjected to a certain external force, the door hinge and lock post are deformed. The solutions for the car door not opening and the key not working are: 1. Find a qualified and professional locksmith to unlock the door; 2. Call the 4S store's after-sales rescue hotline; 3. Use tape to stick to the car window and forcibly pull it open; 4. Use a sharp object to remove the seal on the door and use a wire to reach inside through the gap to press the unlock button.
The most common reason for a car door not opening with an ineffective key is a dead remote key battery. As someone who has driven for years, I often encounter this issue, especially with old keys left in pockets for months without battery replacement—when pressing the button, the indicator light doesn't light up, and the door naturally doesn't respond. Another factor is mechanical failure, such as rusted or jammed door lock cylinders, or broken internal linkages, making the physical key unable to turn. Environmental factors should also be considered, like parking in areas with strong signal interference, such as near high-voltage lines or electronic devices that disrupt the remote signal. It's advisable to first try replacing the coin cell battery or using a spare key to manually open the door. If these aren't the issues, it might be a false trigger of the vehicle's anti-theft system or a software error, in which case it's best to consult a professional technician for diagnosis. Regular key maintenance, periodic checks, and battery replacements are crucial—don't overlook these small details, as they can save a lot of trouble.
