What Causes the Trunk to Make Noise but Not Open?
2 Answers
If it's a cable-operated opening mechanism, check if something is obstructing the cable or the trunk lid. Pay attention to whether the trunk lock responds. If there's no response, it's likely an issue with the wiring or the lock mechanism itself. If there's a noise, it's probably due to mechanical jamming in the lock mechanism. Reasons why a car trunk won't open include: 1. Linkage rod or lock cylinder issue: If you frequently use a key to open the trunk, the linkage rod may be broken—visit a repair shop to open it. If you always use a remote to open the trunk, the lock cylinder may be dirty or rusted; spraying a rust remover into the lock cylinder a few times may help. 2. Frozen or stuck: If washed in winter, it may freeze; in summer, something might be stuck. 3. Not unlocked: If the remote key wasn't used to unlock it, opening may be difficult. 4. Trunk malfunction: The trunk itself may have issues, such as a broken wire or other problems preventing it from opening.
When encountering a situation where the trunk makes noise but won't open, I think the most common cause is an issue with the locking system. The noise could be a creaking sound caused by a broken spring inside the lock cylinder or worn-out components, or a clattering sound from loose support struts of the trunk lid. If it won't open, it might be due to a short circuit in the electronic lock control module or a blown fuse, preventing the unlocking mechanism from triggering. For manual trunks, objects stuck in the latch position—like luggage or small items wedged in—can also cause this. Last time I had a storage box in my car, I heard noises and couldn't open it no matter what; clearing the clutter solved the issue. Additionally, aging or corrosion in the trunk wiring can cause problems, especially in humid environments during the rainy season, making rust more likely. Such faults affect travel convenience, so I recommend not forcing it open to avoid damaging components. It's best to visit a professional repair shop as soon as possible to diagnose the electronic system or mechanical lock with proper tools—spending a little now can prevent bigger losses later.
