How to Solve the Issue of the Trunk Opening When the Car is Locked?
3 Answers
The vehicle's trunk can be electrically controlled to open and close, and there is a door close button inside the trunk lid. By pressing this button, the trunk lid can close automatically without manual intervention.
I've encountered this issue before. Sometimes the car doors are locked but the trunk can still be opened, which is quite annoying. Possible causes include a faulty trunk lock mechanism or electronic system errors, such as poor signal transmission from the remote key. I first tried checking if there was anything stuck or mud on the trunk lock, and cleaning it with a screwdriver solved the problem. If that doesn’t work, try holding down the lock button on the key for a few seconds to reset the system. If these simple fixes don’t help, it might be a blown fuse or a short circuit in the wiring, in which case you’ll need to visit a professional auto repair shop for a diagnostic scan. Regularly lubricating the locks to prevent rust and avoiding water accumulation after rain can help prevent corrosion. These small actions can prevent the problem from worsening, saving you money and hassle while ensuring the trunk stays securely locked while driving, so nothing falls out.
Last time my car was locked but the trunk was open. I suspect there might be an issue with the remote function of the key or the trunk lock itself might be loose. The solution is not difficult: first, try replacing the key battery—in most cases, this will restore normal function. If that doesn't work, manually operate the trunk switch a few times to check for any jamming, or use the manual key to lock the trunk as a temporary measure. I recommend not delaying because driving with an open trunk can easily lead to accidents, such as items falling out due to bumps. My usual maintenance habit is to check the key and lock mechanism every three months, removing dust and foreign objects, which helps reduce problems. When encountering a malfunction, don't panic. Taking it step by step can save time and money. If you really can't fix it, then seek professional help.
