How to Remove Phone Unlock with Smart Watch

If you wear a smart watch, this automatic unlocking might be the result of a convenient but potentially risky feature. While it’s great to skip the login step when your watch is nearby, it can also make your phone less secure, especially if your watch is lost or stolen.
In this comprehensive guide, we’ll show you exactly how to remove phone unlock with smart watch on both Android and iPhone devices. Whether you’re using a Samsung Galaxy Watch, Apple Watch, Wear OS device, or another brand, we’ll walk you through the settings step by step.

By the end of this guide, you’ll have full control over your phone’s lock screen behavior and know how to troubleshoot any issues that come up. Let’s get started!
Why Your Phone Unlocks Automatically with a Smart Watch
Before we dive into the steps, it’s important to understand why your phone unlocks when your smart watch is nearby. This feature is designed for convenience—imagine walking into your office, pulling out your phone, and having it ready to use without typing a code. That’s the idea behind auto-unlock.

Most modern smart watches use Bluetooth and proximity sensors to detect when they’re near your phone. When the two devices are connected and in close range, the phone assumes you’re the legitimate user and bypasses the lock screen. This is often part of a broader security system called trusted devices or trusted accessories.
On Android, this is typically managed through Google’s Smart Lock feature. On iPhones, it’s handled by the Unlock with Apple Watch option in the Watch app. Both systems rely on a secure Bluetooth connection and user authentication (like a passcode on the watch) to verify identity.
While this feature saves time, it introduces a potential security risk. If someone steals your watch, they could potentially unlock your phone—even if they don’t know your PIN. That’s why many users choose to disable this feature, especially if they’re concerned about privacy or live in high-theft areas.
Now that you know why it happens, let’s look at how to turn it off—starting with Android devices.
How to Disable Phone Unlock with Smart Watch on Android
If you’re using an Android phone paired with a Wear OS watch, Samsung Galaxy Watch, or another compatible smart watch, the auto-unlock feature is likely managed through Google’s Smart Lock system. Here’s how to disable it.
Step 1: Open Your Phone’s Settings
Start by unlocking your phone and opening the Settings app. You can usually find this in your app drawer or by swiping down from the top of the screen and tapping the gear icon.
Step 2: Navigate to Security Settings
Scroll down and look for a section labeled Security or Biometrics and Security. The exact name may vary depending on your phone’s manufacturer (e.g., Samsung, Google Pixel, OnePlus).
Step 3: Find Smart Lock
Tap on Smart Lock. You may be asked to enter your PIN, pattern, or password to proceed—this is a security measure to prevent unauthorized changes.
Step 4: Locate Your Smart Watch
Inside Smart Lock, you’ll see a list of trusted devices. Look for your smart watch in the list. It might be labeled by name (e.g., “Galaxy Watch5” or “Wear OS by Google”).
Step 5: Remove the Watch from Trusted Devices
Tap on your watch’s name, then select Remove or Turn off. Confirm the action when prompted. This will disable the auto-unlock feature for that device.
Step 6: Test the Change
Lock your phone and step away from your watch (or turn off Bluetooth on the watch). Try unlocking your phone—it should now require your PIN, pattern, fingerprint, or face scan.
Pro Tip: If you have multiple trusted devices (like a car Bluetooth system or a smart speaker), make sure you only remove the watch unless you want to disable all auto-unlock features.
How to Disable Phone Unlock with Apple Watch on iPhone
If you’re an iPhone user with an Apple Watch, the process is slightly different but just as straightforward. Apple’s system is tightly integrated, so you’ll need to use the Watch app on your iPhone to make changes.
Step 1: Open the Watch App
On your iPhone, locate and open the Watch app. It has a white icon with a blue watch face and is usually found on your home screen or in the Utilities folder.
Step 2: Go to the My Watch Tab
At the bottom of the screen, tap the My Watch tab (it looks like a watch face). This is where you manage all settings related to your Apple Watch.
Step 3: Tap on Passcode
Scroll down and tap on Passcode. You may need to enter your iPhone passcode or use Face ID/Touch ID to proceed.
Step 4: Toggle Off “Unlock with Apple Watch”
Look for the option labeled Unlock with Apple Watch. It will have a toggle switch next to it. Simply tap the switch to turn it off.
Step 5: Confirm the Change
You may see a confirmation message explaining that your iPhone will no longer unlock automatically when your Apple Watch is nearby. Tap Turn Off to confirm.
Step 6: Test the Feature
Lock your iPhone and try waking it up while wearing your Apple Watch. It should now require you to enter your passcode or use Face ID/Touch ID—even if the watch is unlocked and on your wrist.
Note: If you later decide you want the convenience back, you can easily re-enable this feature by following the same steps and toggling the switch back on.
What Happens After You Disable Auto-Unlock?
Once you’ve turned off the auto-unlock feature, your phone will behave more securely—but also less conveniently. Here’s what to expect:
- Manual authentication required: Every time you wake your phone, you’ll need to enter your PIN, pattern, password, or use biometric authentication (fingerprint or face scan).
- No more instant access: You won’t be able to pick up your phone and start using it immediately if your watch is nearby.
- Improved security: Your phone is now much harder to unlock if your watch is lost or stolen.
- Bluetooth still works: Disabling auto-unlock doesn’t affect other Bluetooth functions like notifications, music control, or health tracking.
For many users, the trade-off is worth it. If you’re in a public place or traveling, the extra layer of security can give you peace of mind. However, if you’re at home and value convenience, you might consider re-enabling the feature in safe environments.
Troubleshooting Common Issues
Sometimes, disabling auto-unlock doesn’t work as expected. Here are some common problems and how to fix them.
Issue 1: Phone Still Unlocks Automatically
If your phone continues to unlock when your watch is nearby, even after disabling the feature, try these steps:
- Restart both devices: Turn off your phone and watch, wait 30 seconds, then turn them back on.
- Re-pair your watch: Unpair your watch from your phone, then set it up again. This resets the connection and often resolves glitches.
- Check for software updates: Make sure both your phone and watch are running the latest operating system version.
Issue 2: Smart Lock Option Is Missing
On some Android phones, especially those from Samsung or Xiaomi, the Smart Lock option may be buried or renamed. Try searching for “Smart Lock” in the Settings search bar. If it’s not there, look under Lock Screen or Advanced Security.
Issue 3: Watch App Doesn’t Show Passcode Option
If you can’t find the Passcode section in the Watch app on iPhone, make sure:
- Your Apple Watch is paired and connected.
- You’re signed in with the same Apple ID on both devices.
- The watch has a passcode set (required for the feature to work).
Issue 4: Bluetooth Disconnects Frequently
If your watch keeps disconnecting after disabling auto-unlock, it’s likely unrelated. Try:
- Moving closer to your phone.
- Turning off battery-saving modes on the watch.
- Resetting network settings on your phone (Settings > General > Reset > Reset Network Settings on iPhone; Settings > System > Reset > Reset Wi-Fi, mobile & Bluetooth on Android).
Tips for Balancing Security and Convenience
Disabling auto-unlock is a smart move for security, but you don’t have to sacrifice all convenience. Here are some tips to find the right balance:
- Use location-based unlocking: Some Android phones let you set your home or office as a “trusted place” where the phone stays unlocked. This gives you convenience at home without compromising security elsewhere.
- Enable biometric authentication: Use fingerprint or face unlock for quick access while keeping your phone secure.
- Re-enable auto-unlock temporarily: If you’re at home and want convenience, turn the feature back on. Just remember to disable it when you leave.
- Use a strong watch passcode: If you keep auto-unlock enabled, make sure your smart watch has a strong passcode or PIN to prevent unauthorized access.
- Monitor your devices: Regularly check which devices are trusted on your phone and remove any you no longer use.
Final Thoughts
Learning how to remove phone unlock with smart watch is a simple but powerful way to take control of your digital security. Whether you’re using an Android phone with a Wear OS watch or an iPhone with an Apple Watch, the steps are straightforward and take just a few minutes.
While auto-unlock is convenient, it’s not worth the risk if your watch is lost or stolen. By disabling this feature, you ensure that only you—or someone who knows your PIN—can access your phone. And if you ever change your mind, you can always turn it back on.
Remember, security isn’t about making life harder—it’s about making smart choices. With the tips and steps in this guide, you can enjoy the benefits of your smart watch without compromising your privacy.
Now that you know how to disable auto-unlock, take a moment to test your settings and enjoy the peace of mind that comes with a truly secure phone.
