Why Can't the Trunk Lock of Fengguang 580 Be Opened?

The reasons why the trunk lock of Fengguang 580 cannot be opened are as follows: 1. Linkage rod or lock cylinder issue: If you frequently use the key to open the trunk lid, it may be due to a broken linkage rod, which requires repair at a service center. If you always use the remote control to open the trunk lid, it might be due to dirt or rust in the lock cylinder. Spraying rust remover into the lock cylinder a few times can help open it. 2. Not unlocked: The trunk is difficult to open because it wasn't unlocked with the remote key. It's best to press the unlock button on the key before opening or check if the key battery has power. 3. Mechanical part failure: The trunk itself may have issues, such as damaged wiring or other trunk-related problems causing the trunk to not open.

I also experienced the issue with the Fengguang 580's trunk lock not opening last time, and it was quite frustrating. The most common reason is the lock cylinder getting stuck, especially when dust or dirt accumulates, blocking the mechanical operation; or the key might be worn out, making it difficult to turn smoothly. For electric locks, a dead remote battery or signal interference (e.g., parking near high-voltage lines) could trigger the malfunction. I first tried manually turning the key, and if that didn’t work, I sprayed some household lubricant and gently tapped the lock area to loosen debris. I usually recommend cleaning around the lock after parking and using a cotton swab monthly to prevent rust. If the problem persists, it’s best to visit a professional repair shop promptly to avoid more severe damage or safety hazards. A malfunctioning trunk lock also affects luggage access, and delaying repairs could lead to unnecessary travel disruptions—fixing it early saves money too.

The trunk lock malfunction can be analyzed from a technical perspective: First, electrical system failures, such as a blown fuse (look for the trunk-related label in the fuse box), can interrupt the current; short circuits or open circuits in the wiring can also cause issues, commonly due to moisture or aging. On the mechanical side, the lock hook may be deformed, rusted, or misaligned, causing it to jam when encountering bumps. During inspection, I first observe whether the lock operates smoothly and use a flashlight to check the lock's condition; if it's electric, try using the emergency trunk release handle (usually located under the seat back inside the car) to switch to manual mode. When repairing, don’t rush to replace the entire lock—adjusting components or cleaning the circuit may solve the problem. Other similar vehicles often experience this issue, and I’ve learned to use a multimeter to measure basic circuit values to avoid over-reliance on external assistance.

Safety is the top priority. If the trunk lock of the Fengguang 580 won't open, it must be addressed immediately: the lock cylinder may be broken or the electronic system may have failed. Forcing it open can easily damage the car body. First, I'll check the vehicle manual to confirm if there's an emergency unlocking method; turn on the hazard lights and pull over; seek remote assistance or try the internal release cord inside the trunk (some cars are designed with an emergency opening feature). The issue is often caused by aging locks or weather changes (freezing in winter); don't neglect it while driving. Visit a professional shop early to inspect the electrical and mechanical structures, ensuring normal operation.
