How to Add a Second NFC for BYD?

The other phone must have NFC functionality. Install and log in to BYD Cloud Service on the second phone, then go to My -- NFC Key -- there will be an option to add. After adding, you can uninstall BYD Cloud Service from that phone to prevent others from tracking your trips, but the key function will still work normally.

I just bound the NFC key to my wife's phone, so she doesn't have to keep looking for my keys when driving. The process is actually quite simple: First, start the vehicle in the car, open the central control screen, and enter the 'Vehicle Settings' menu. Find the 'NFC Key Management' option. After verifying identity with the original owner's key, click 'Add New Key.' Then, place my wife's phone near the wireless charging panel on the central console (the exact location of the sensing area may vary slightly depending on the car model). A beep sound indicates the system has successfully recognized it. Finally, remember to name the new key for easy management, such as 'Wife's Exclusive,' to avoid confusion later about which key is bound to which phone. The whole process takes just three minutes, but the phone must have NFC enabled. BYD supports mainstream phone models like Huawei and Xiaomi. Now, going out is really convenient—both phones can be used as car keys, completely eliminating the awkwardness of forgetting keys.

As a digital product enthusiast, I find BYD's mechanism for adding a second NFC key to be very user-friendly. The specific operation path is in the vehicle's system: Vehicle Settings - Smart Key - NFC Key option. After administrator verification with the original authenticated key, place the new device (phone or card) near the induction area around the gear shift for about 10 seconds, and the system will complete the pairing. Here's a practical tip: It's recommended to disable the transit card function in the phone's wallet when family members use it to avoid interference with recognition—my Huawei Mate40 once experienced recognition failure. Additionally, note that up to ten NFC devices can be added, but in practice, three devices are sufficient for family use. It's advisable to clearly label each key with the user's name for easy management of deactivated devices later. The entire process is more secure than Bluetooth keys due to physical contact and doesn't drain the phone's battery, making it the most convenient car key solution in my opinion.

Last time I helped a friend set up a BYD spare key, just remember these three steps: 1. Locate the key management menu on the vehicle's central display; 2. Authenticate identity using the original car key; 3. Place the new phone near the in-car induction zone until success is prompted. The whole process doesn't require connecting to any APP - the key point is to align the phone's back NFC chip with the induction zone. After binding, it's recommended to personally test whether the unlocking function works properly.

Adding a second NFC key is particularly practical for households with multiple drivers. The specific steps are: access the digital key page in the vehicle settings via the central control screen, and the system will prompt you to verify permissions using the original key. After successful verification, place the new device (supports phones and card keys) as instructed, and the binding is complete once you hear the confirmation tone. After binding, I prefer to name the new key with family members' names for easy identification. The best part is that this feature operates completely independently—even if your phone is powered off, it still works. Last time, my phone was dead, but I could still unlock the car and drive home smoothly, proving its high reliability. The only limitation is that the new device must be factory-supported with NFC functionality.

Adding a new NFC key actually tests attention to detail: First, ensure the vehicle's system is updated to the latest version to avoid compatibility issues. Before binding, confirm that the phone's NFC function is enabled, then fully align the back of the phone with the marked area in front of the center console (refer to the manual for the exact location). Do not move the device during the binding process—completion is signaled by a system vibration. Important safety reminder: If the phone is lost, immediately delete the corresponding key information by long-pressing the key in the vehicle's key management page to unbind. This operation is recommended to be checked quarterly. Practical tests show the recognition response is about half a second faster than a physical key, proving it to be both convenient and secure.
