What to Do When the Door of BYD Song Won't Open?
4 Answers
Here are the reasons and solutions for the BYD Song key not opening the door: 1. Dead battery: If the car battery is dead, the car cannot start, and the sensing system naturally fails. In this case, charging the car will solve the problem. 2. Dead key fob battery: Generally, the battery in the key fob lasts for about 2 years. If the battery is dead, you can only use the spare mechanical key inside the key fob to open the door. For vehicles with a push-button start, even if you open the door, the car cannot start when the key fob battery is dead. In this case, simply place the key fob near the sensor and then start the car. Note that the location of the sensor varies for different cars. 3. Signal interference: In this situation, you can only try moving around the car at different distances and angles to see if luck strikes. Additionally, pressing the unlock button while making a phone call can increase the success rate.
When encountering a situation where the BYD Song's door won't open, my first thought is the remote key issue. If the battery is dead or there's signal interference, it may fail. Try replacing it with a new CR2032 battery or removing the interference source. Next, check the mechanical lock. There's a small cover under the Song's door handle—lift it and use the spare key to manually unlock. If it's stuck, spray some WD-40 lubricant. Then consider electronic system failures, such as a blown fuse or door control module issue. Use the emergency lever in the trunk to access and check the fuse box. If it still won't open, it might be due to incorrect child lock settings—ensure the rear door child lock is not activated. In any case, avoid forcing the door open to prevent damage. Prioritize safety by calling a professional tow truck or visiting a 4S store for diagnosis. For prevention, I regularly clean the door grooves and lubricate the lock mechanism, and check the battery annually to reduce such troubles.
I've been driving my BYD Song for several years, and door unlocking issues commonly occur due to remote control failure. First, try replacing the battery or pressing the unlock button close to the door for testing; the physical lock is also very effective - locate the hidden hole on the door handle and use the key to open it. Once my car was frozen shut, and pouring some warm water solved the problem; another time, the child lock was accidentally activated, making exterior pulling ineffective, but resetting it via the central control restored normal function. For electronic faults, try using the BYD app on your phone for remote control, which is very convenient when connected to the internet; if all else fails, access through the trunk to check fuses or relays. For daily maintenance, I focus on cleaning door seams during car washes and lubricating the locks monthly to prevent sticking; if none of these methods work, seek help from a repair shop to avoid damaging the paint or circuits by forcing it.
As a Song car owner, don't panic if the door won't open. First, check if the remote control battery is dead and try replacing it. Press the unlock button near the door to rule out interference. Use the manual method with the spare key to open the lock hole. Check if the child lock setting is incorrect. If mechanically stuck, spray lubricant to ease it. The emergency trunk entry lever can be used. In case of software failure, turn off and restart the vehicle. If frozen, let it thaw slowly. Seek timely assistance from a 4S store or professional technician for inspection and repair. Regular maintenance of the locking mechanism can prevent problems.
