What's the reason for one car door not opening?
2 Answers
The reasons for a car door not opening are as follows: 1. The remote key is out of battery: If the door cannot be opened using the remote key, it is likely that the remote key is out of battery, the car battery is dead, or there is strong signal interference nearby. Generally, the remote key has a hidden mechanical key inside. 2. If you have the mechanical key but cannot find the keyhole on the door, it is because the manufacturer has hidden the keyhole for aesthetic reasons. 3. In this case, you need to carefully observe the door handle. Usually, there is a decorative piece at the end of the handle that is about the size of the key. You can pry it open to reveal the keyhole.
Recently, my car also has a door that won't open. This kind of problem is quite common and usually stems from issues with the door lock mechanism. It could be that the lock cylinder is jammed, especially during hot summers or cold winters when lubricant dries up, making it harder to turn. Alternatively, the connecting cable for the door handle might have come loose, resulting in no response when pulled. Another possible cause could be the accidental activation of the child lock—check this small switch from inside the car. If you've used the remote key to unlock but the door doesn't respond, the receiver module might be faulty, failing to transmit the signal. When I encounter this, I first try using the manual key to unlock. If that doesn't work, I check whether the cable is broken. Don’t forget that door frame deformation or obstruction can also cause issues, often as a lingering effect after an impact. For regular maintenance, remember to clean dust from door gaps and apply lubricant periodically to keep the mechanism smooth, which helps reduce the chance of malfunctions. If all else fails, take it to a professional repair shop—safety first, and avoid forcing it open yourself.
