您的Apple Watch是否无法解锁您的 iPhone？许多原因（例如蓝牙(Bluetooth)和Wi-Fi问题、过时的系统软件和损坏的网络设置）通常会导致这种情况。
通过以下建议和解决方案，让您的Apple Watch重新开始解锁您的 iPhone。
在你开始前
尽管在您的 iPhone 上激活了“使用 Apple Watch 解锁(Unlock with Apple Watch)”，但该功能不会生效，除非您：
- 佩戴您的Apple Watch。watchOS 使用一种称为手腕检测(Wrist Detection)的功能来确定这一点。
- 每次佩戴Apple Watch时手动解锁 iPhone 。
- 记得(Remember)解锁您的Apple Watch。
仔细检查蓝牙和 Wi-Fi
Apple Watch(Apple Watch)和 iPhone 使用蓝牙(Bluetooth)和Wi-Fi相互通信。因此(Hence)，最好通过检查蓝牙(Bluetooth)和Wi-Fi无线电是否已在每台设备上启动并运行来开始。
苹果手机(iPhone)
(Swipe)从屏幕右上角向下滑动，打开 iPhone 的控制中心(Control Center)。然后，确保蓝牙(Bluetooth)和Wi-Fi图标处于活动状态。如果没有，请点击以激活它们。
苹果手表(Apple Watch)
按下数字表冠(Digital Crown )并选择设置(Settings)（齿轮形图标）。然后，向下滚动并点击蓝牙(Bluetooth)和Wi-Fi。如果后续屏幕中的开关未激活，请将其打开。

苹果手机(iPhone)
1.打开iPhone的控制中心(Control Center)，禁用蓝牙(Bluetooth)和Wi-Fi。然后，点击飞行模式(Airplane Mode )图标并等待 10 秒钟，然后再次点击该图标。然后重新激活蓝牙(Bluetooth)和Wi-Fi。
苹果手表(Apple Watch)
进入设置(Settings)应用程序并禁用蓝牙(Bluetooth)和Wi-Fi。接下来，退出表盘，向上滑动以打开控制中心(Control Center)，然后激活和停用飞行模式(Airplane Mode)。最后，重新访问设置(Settings)应用程序并重新激活蓝牙(Bluetooth)和Wi-Fi。
重启 iPhone 和 Apple Watch
下一个修复涉及重新启动两个设备。这会刷新系统缓存并帮助解决导致Apple Watch无法解锁 iPhone 的其他软件相关故障。
苹果手机(iPhone)
打开设置(Settings)应用程序，然后点按常规(General)>关机(Shut Down)。然后，拖动滑动以关闭电源(Slide to Power Off)滑块以关闭设备。等待(Wait)10-20 秒，然后按住侧面(Side)按钮重新启动它。

How To Fix Apple Watch Not Unlocking iPhone
Is your Apple Watch not unlocking your iPhone? Many reasons—such as iѕsues with Bluetooth and Wi-Fi, outdated ѕystem software, and corrupt network settings—often cause that.
Work your way through the suggestions and solutions below to get your Apple Watch to start unlocking your iPhone again.
Before You Start
Despite activating ‘Unlock with Apple Watch‘ on your iPhone, the functionality won’t kick into action unless you:
- Wear your Apple Watch. watchOS uses a feature called Wrist Detection to determine that.
- Manually unlock your iPhone each time you strap your Apple Watch.
- Remember to unlock your Apple Watch.
Double-Check Bluetooth and Wi-Fi
Your Apple Watch and iPhone use Bluetooth and Wi-Fi to communicate with each other. Hence, it’s best to kick things off by checking that both the Bluetooth and Wi-Fi radios are up and running on each device.
iPhone
Swipe down from the top-right of the screen to open the iPhone’s Control Center. Then, make sure that the Bluetooth and Wi-Fi icons are active. If not, tap to activate them.
Apple Watch
Press the Digital Crown and select Settings (cog-shaped icon). Then, scroll down and tap Bluetooth and Wi-Fi. If the switches in the subsequent screens aren’t active, turn them on.
Toggle Airplane Mode
Toggling Airplane Mode on your iPhone and Apple Watch helps reboot the Bluetooth and Wi-Fi radios inside. That’s a quick way to eliminate any random glitches preventing the devices from talking with each other.
iPhone
1. Open the iPhone’s Control Center and disable Bluetooth and Wi-Fi. Then, tap the Airplane Mode icon and wait for 10 seconds before tapping the icon again. Follow that by reactivating Bluetooth and Wi-Fi.
Apple Watch
Head into the Settings app and disable Bluetooth and Wi-Fi. Next, exit to the watch face, swipe up to open the Control Center, and follow by activating and deactivating Airplane Mode. Finally, revisit the Settings app and reactivate Bluetooth and Wi-Fi.
Restart iPhone and Apple Watch
The next fix involves restarting both devices. That flushes the system caches and helps resolve other software-related glitches resulting in the Apple Watch not unlocking the iPhone.
iPhone
Open the Settings app and tap General > Shut Down. Then, drag the Slide to Power Off slider to shut down the device. Wait for 10-20 seconds before holding down the Side button to reboot it.
Apple Watch
Press and hold the Side button and drag the Power Off slider to shut down the device. Then, wait for 10-20 seconds and hold down the Side button again to restart it.
Disable/Re-enable Unlock with Apple Watch
If your Apple Watch still fails to unlock your iPhone, try deactivating and reactivating ‘Unlock with Apple Watch.’ Setting up the functionality from scratch just might help fix the issue.
To do that, open the Settings app on your iPhone, tap Face ID & Passcode, and enter your iPhone’s Lock Screen passcode. Then, scroll down to the Unlock with Apple Watch section and turn off the switch next to [Your Name]’s Apple Watch.
Next, restart both the iPhone and Apple Watch, head back into your iPhone’s Face ID & Passcode settings, and reactivate Unlock with Apple Watch.
Reset Face ID on iPhone
Since Face ID is closely linked with the ‘Unlock with Apple Watch’ functionality, your next shot at fixing the issue involves resetting your Face ID profile.
To do that, open the iPhone’s Settings app and select Face ID & Passcode. Then, enter your device passcode and tap Reset Face ID.
Finally, restart your iPhone, re-enter the Face ID & Passcode settings, and tap Set Up Face ID to set up your Face ID profile from scratch.
Reset Passcode on Apple Watch
If ‘Unlock with Apple Watch’ continues to fail to work, try resetting your Apple Watch’s passcode. To do that, open the Watch app on your iPhone and tap Passcode. Then, tap Turn Passcode Off to remove your Apple Watch’s passcode. Follow by tapping Turn Passcode On to set up a passcode again.
Note: Resetting the Apple Watch’s passcode disables ‘Unlock with Apple Watch,’ so don’t forget to reactivate it by visiting your iPhone’s Face ID & Passcode settings.
Update iOS and watchOS
Updating iOS and watchOS can help rule out known system software-related issues from interfering with ‘Unlock with Apple Watch.’ For example, Apple acknowledges a problem on the iPhone 13 that results in an “Unable to Communicate with Apple Watch” error. Upgrading to iOS 15 and watchOS 8 is the recommended fix.
iPhone
Open the Settings app and go to General > Software Update. If you see a pending iOS update, tap Download & Install.
Apple Watch
Place your Apple Watch on its charger. Then, press the Digital Crown and go to Settings > General > Software Update. If you see a pending watchOS update, tap Download & Install.
Alternatively, open the iPhone’s Watch app and tap General > Software Update > Download & Install to update your Apple Watch.
Reset the iPhone’s Network Settings
Corrupt or conflicting network settings on your iPhone can also play a role in preventing your Apple Watch not unlocking it. So, it’s a good idea to reset them.
To do that, open the iPhone’s Settings app and go to Settings > General > Transfer or Reset iPhone. Follow that by tapping Reset Network Settings.
Backup and Reset Your Apple Watch
If the issue continues or recurs occasionally, consider resetting the Apple Watch. That is the best way to resolve underlying problems in watchOS.
To do that, open the Watch app, select All Watches (located at the top-right corner of the My Watch tab), tap the Info icon next to your Apple Watch, and tap Unpair Apple Watch. Your iPhone will then back up and reset your watchOS device.
After that, continue by reconnecting the Apple Watch to your iPhone. You’ll receive an option to restore your data during the setup procedure.
For detailed step-by-step instructions, here’s how to backup and restore an Apple Watch.
Backup and Reset Your iPhone
If none of the fixes above worked, it’s time to factory reset your iPhone. Just make sure to create a backup of your data so you can restore everything after the reset procedure. Also, don’t forget to set up ‘Unlock with Apple Watch’ afterward. That should hopefully take care of the problem for good.
