What to Do When the BYD S6 Trunk Won't Open?

There is a cover near the door lock that can be removed; just flip the mechanism inside to open it. The most likely reason for it not opening is that the three screws on the door lock motor have fallen off. Here is some relevant information: 1. S6 Introduction: The S6 excels in small storage compartments, with almost everywhere offering a spot to place personal items, and the locations are quite obvious. The rear armrest has a good texture and can also function as a cup holder. 2. Storage Space: In terms of storage space, the BYD S6 leverages its inherent spaciousness, avoiding the need to sacrifice storage due to space constraints. Moreover, it features thoughtful adjustments in the details, ensuring it has everything you'd expect.

Last time my car trunk wouldn't open either, and after struggling for a while I found the cable was stuck. This car actually has three ways to open the trunk: remote key fob, dashboard button, and trunk release button. I tried them all but none worked. When I peeked at the trunk lock, turns out the cylinder was frozen - happens easily in winter. Just blow hot air into the lock with a hairdryer for two minutes to thaw it. If it happens in summer, most likely it's either a rusted latch or broken cable. By the way, there's an emergency release handle inside the trunk too - you might get it open by climbing from the backseat and pulling it. If all else fails, just contact the 4S shop - their diagnostic tool will instantly tell whether it's a wiring issue or control module failure.

My S6 had the same issue a while back, and after some troubleshooting, I found out the key battery was dead. Before you rush to dismantle the lock, try using the mechanical key to open the trunk lock cylinder. If the lock cylinder won't turn, it might be stuck due to rust—spraying some WD40 can help. Also, check the central locking button inside the car; sometimes accidentally pressing the child lock can cause the trunk to lock. The fuse box is under the steering wheel—refer to the manual to locate the 15A fuse for the trunk and replace it if it's blown. If none of these methods work, you might need to replace the entire lock assembly.

Just dealt with this issue last week. Used a diagnostic tool to read the fault codes, which indicated a BCM module communication error. The trunk lock of this BYD model is controlled by the body control module – if the module crashes, all electronic controls will fail. The emergency solution is to disconnect the negative battery terminal for ten minutes to reboot the module. Also note that improper wiring during aftermarket reverse camera installation can easily cause harness shorts; the trunk wiring harness is located behind the left-side trim panel. In winter, frozen seals may also jam the latch – pour some warm water before opening. If both key fob and interior button controls fail completely, expect around 500 RMB in repair costs.

A friend's car had this issue before—the trunk just wouldn't open. Focus on checking these six areas: First, ensure all doors unlock properly; if any door lock fails, it might be a central control issue. Next, check the remote key's battery level. Then, try the trunk button on the floor near the driver's seat. Insert the mechanical key into the trunk lock cylinder and turn it several times. Peel back the inner trunk trim panel to pull the emergency release cord. Finally, inspect the No. 15 fuse in the fuse box. In our case, the wiring harness had been chewed through by mice—reconnecting it cost 80 yuan. Such problems are best dealt with early for peace of mind.

My experience is to start with the simple checks. Open the driver's door and crouch down. There are two fuse boxes below the steering wheel on the left side. Look for the fuse labeled with the trunk icon to see if it's blown. Then check the response of the remote key buttons—try holding the unlock button for three seconds. Here's a detail for the interior: when pressing the central control unlock button, it only works if the driver's door is open. Insert the mechanical key into the trunk lock and turn it clockwise all the way until you hear a click, indicating it's unlocked. If none of these methods work, it's recommended to remove the tailgate trim panel and manually pull the cable. However, it's best to have a professional handle it, as doing it yourself might break the clips.
