What Causes the BYD Han's Trunk to Not Open?
4 Answers
Reasons why the BYD Han's trunk won't open: There may be foreign objects stuck in the trunk lock, preventing it from opening. Below is an introduction to the BYD Han: 1. Configuration: Features a 12.3-inch LCD instrument panel and a 15.6-inch rotatable central control LCD screen. Equipped with a total of 6 USB ports—4 in the front and 2 in the rear. Supports the mobile phone NFC car key function, allowing the car to be unlocked by simply bringing the phone close, without the need to power on or connect to the internet. 2. Power: Utilizes a new lithium iron phosphate Blade Battery, which significantly improves the discharge rate. The battery has a lifespan of 8 years or 1.2 million kilometers, reduces costs by 30%, and increases the volumetric energy density by 50%. The space utilization rate of the Blade Battery is about 60%, compared to approximately 40% for traditional battery packs.
The other day I drove my friend's BYD Han, and the trunk just wouldn't open no matter what—it was really embarrassing. There are quite a few common reasons for this kind of issue. For example, the trunk's electronic lock might be stuck or the motor could be faulty—especially if the car is often driven on muddy roads, as dirt getting inside can make the lock less responsive. Also, if the key's battery is nearly dead, it won't send a signal, so pressing the button won't do anything. Or the trunk switch button on the car itself might be broken, making it unresponsive. Another key factor is a blown fuse—if the circuit is overloaded, it can burn out, cutting power to the entire lock. Wiring degradation is also an issue; BYD's wiring might have poor connections, especially after a few years of use. Safety is crucial—if you can't access your luggage or it blocks emergency escape, pull over immediately to check the key and button. If that doesn't work, head to a 4S shop and let a technician take a look—don't try to force it open yourself.
As a car enthusiast, I'm quite familiar with the electronic control system of the BYD Han. The inability to open the trunk is usually related to electronic components. The relay in the lock mechanism may have burnt contacts or a faulty coil, preventing current transmission. On the signal level, a depleted remote key battery or module mismatch can cause communication loss. Issues with the vehicle's body control computer are also possible since it manages the trunk's opening logic. A blown fuse is a common culprit, typically located in the fuse box labeled with F2x series numbering; short circuits or poor connections in the wiring, especially loose connectors that vibrate repeatedly, can easily lead to breaks. It's recommended to use a multimeter to check voltage or try replacing the key; if the lock mechanism is faulty, it's more troublesome and requires disassembly for inspection. It's best to address the issue early to avoid travel delays.
If you encounter a situation where the trunk won't open, don't panic immediately. I suggest first checking simple things. For example, whether the key battery is dead—try replacing it with a new button battery; see if the car's button is stuck or damaged. If a fuse is blown, look for the trunk fuse in the small box on the left side of the driver's seat and replace it; if there's a loose wiring connection, tighten the plug. These are all things you can try yourself. If they don't solve the problem, it might be a faulty lock mechanism or control module. In this case, don't force it open as it could damage the car. For safety, pull over, turn on the hazard lights, and contact a repair shop for assistance.
