How to Deactivate the BYD S6 Anti-Theft System?
3 Answers
Disconnect the power for 15 minutes, then reconnect to see if it can be deactivated. After unlocking the car door, insert the spare key within 15 seconds, turn it to the ON position to illuminate the dashboard, then turn it off and repeat this cycle 10 times consecutively to force deactivation.
I've got some experience to share about deactivating the BYD S6 anti-theft system. Normally, after the system is activated, you can try pressing the unlock button on the original remote control - usually it deactivates in one or two presses. If there's no response, check if the remote's battery is dead and replace it with a new one before trying again. If that still doesn't work, use the mechanical key to open the door and sit in the driver's seat. Don't rush to start the car - first turn the key to the ACC position three times, pausing a few seconds between each turn, to let the system reset itself. Sometimes low battery voltage can falsely trigger the anti-theft system, so charging the car battery for a while before retrying can also help. I've encountered similar issues with my BYD before - just be patient and repeat the operations a few times. If this method still fails, don't force it - go directly to a BYD 4S store for inspection. They have specialized tools for diagnosis and resetting to avoid damaging other components. Developing a habit of using spare keys regularly can save you a lot of trouble.
There are many common faults in deactivating the anti-theft system, and the first step is to identify the cause. When the remote control fails, check the battery power and press the unlock button after replacing it; if it still doesn't work, manually open the door with the key, gently turn the ignition switch to the ON position, wait a few seconds, and then start the car—the system will most likely reset. The BYD S6's anti-theft system may mistakenly lock due to vibration or a weak battery, and restarting after charging usually solves the issue. I've found that the door lock status is also crucial—try locking and then unlocking the car once. If these methods don’t work, don’t waste time—take it to a professional repair shop to scan for fault codes. They also recommend regular maintenance of the anti-theft system to prevent rust or loose connections. Addressing issues promptly not only ensures safety but also extends the vehicle's lifespan.
