What to Do When the Trunk of BYD Han Won't Open?
4 Answers
Here are the reasons and solutions for the trunk of BYD Han not opening: 1. Trunk switch failure: A faulty trunk tailgate switch can prevent the owner from opening the trunk by operating the tailgate switch. The maintenance technician can use tools to open the trunk, remove the tailgate switch, and use a multimeter to check if the trunk switch is faulty. The trunk tailgate switch can be replaced. If the issue is not caused by human factors and the vehicle is under warranty, the trunk switch can be replaced for free at a 4S store. 2. Trunk lock block failure: A faulty trunk lock block can prevent the trunk from opening or closing normally. The maintenance technician can use tools to open the trunk, remove the tailgate lining, check if the trunk lock block latch moves normally, and use a multimeter to measure the resistance of the lock block motor to determine if it is faulty. The trunk lock block assembly can be replaced. If the issue is not caused by human factors and the vehicle is under warranty, the trunk lock block can be replaced for free at a 4S store; if the vehicle is out of warranty, the replacement will need to be paid for by the owner. 3. Car key battery is dead: A depleted car key battery can prevent the owner from opening the trunk tailgate using the trunk unlock button on the car key. Replace the car key battery (model CR2032). The car key battery is a consumable item and is not covered under the vehicle warranty, so the owner will need to pay for the replacement.
The trunk won't open? It depends on the specific situation. Physical lock jams are quite common, especially after car washes when rust tends to form. Try turning the key clockwise a few times - sometimes the keyhole freezes and needs a heat gun. Electronic faults require more careful troubleshooting: long-press the trunk button on your remote to test response, and check if the central display shows any disabled button warnings. I've heard some BYD Han models had poorly designed trunk wiring harnesses in certain batches, where repeated opening/closing could break wires - as an experienced mechanic, I've encountered two such cases. If all else fails, crawl into the back seat and use the emergency release - just pull the small orange fabric tab on the left side of the interior lining.
If the power tailgate malfunctions, try initializing a reset: Hold down the tailgate button on the driver's door panel until you hear a beep. If the central display shows a tailgate fault code, it's likely that the sensor was triggered by luggage in the trunk activating the anti-pinch protection. Remember to check if there are any coins stuck under the carpet blocking the latch—last time I helped a neighbor, it was a fifty-cent coin causing the issue. Insufficient battery in the electronic key can also cause sensing failure; replacing the battery might just solve the problem.
What about using a mobile app to unlock it? Currently, BYD Cloud Service allows remote control of the tailgate. However, make sure to update the app to the latest version, as older versions may have compatibility issues. If the trunk won't open, it's recommended to perform a system restart first: turn off the engine and disconnect the power for ten minutes to let the vehicle's computer reset. Last time when I was dropping my kid off at school, this happened, and it worked fine after the reset. Also, remember to clean the camera and radar sensors, as mud or debris can interfere with the electric opening and closing mechanism.
