How to Remove Auto Unlock from Smart Watches
Smart watches have revolutionized the way we stay connected, track fitness, and manage daily tasks. From receiving notifications to monitoring heart rate, these wearable devices are now essential companions. One popular convenience feature is auto unlock, which allows your smart watch to unlock automatically when your paired phone is nearby or unlocked. While this sounds handy, it can also pose a serious security risk—especially if your devices fall into the wrong hands.
In this comprehensive guide, you’ll learn how to remove auto unlock from smart watches across the most popular platforms, including Apple Watch, Wear OS (used by brands like Fossil, TicWatch, and Google Pixel Watch), and Samsung Galaxy Watch. We’ll walk you through step-by-step instructions, explain why disabling this feature is a smart move for privacy, and offer troubleshooting tips if things don’t go as planned.
Whether you’re concerned about data security, want to prevent accidental unlocks, or simply prefer full manual control over your devices, this guide has you covered. Let’s dive in and take back control of your smart watch’s access settings.
Why You Should Remove Auto Unlock from Your Smart Watch

Before we get into the technical steps, it’s important to understand why you might want to disable auto unlock in the first place. While the feature is designed for convenience, it can inadvertently compromise your digital safety.
One major concern is unauthorized access. If your phone and watch are linked via auto unlock, someone who gains temporary access to your phone—say, a curious friend or a thief—could potentially unlock your watch without needing a passcode. This opens the door to sensitive information like health data, messages, payment apps (like Apple Pay or Google Pay), and even location history.
Another issue is accidental activation. Auto unlock can sometimes trigger when you don’t expect it—like when your phone is in your pocket and your watch wakes up unintentionally. This not only drains battery life but can also lead to unintended actions, such as sending a message or opening an app.
Privacy is another key factor. Many users don’t realize that auto unlock creates a constant Bluetooth handshake between devices. While encrypted, this connection can still be exploited in rare cases through advanced attacks like relay or spoofing techniques.
Finally, some people simply prefer manual control. Knowing that your watch only unlocks when you choose to enter a passcode or use biometric authentication (like a fingerprint or face scan) gives you peace of mind.
By removing auto unlock, you’re not losing functionality—you’re gaining security. And the good news? It’s easy to do on all major smart watch platforms.
How to Remove Auto Unlock from Apple Watch
Apple Watch is one of the most popular smart watches on the market, and its integration with iPhone makes auto unlock a default feature for many users. However, Apple gives you full control over this setting, and disabling it takes just a few taps.
Step 1: Open the Watch App on Your iPhone
Start by unlocking your iPhone and locating the Watch app. This is the official app Apple provides to manage all settings for your Apple Watch. It’s usually found on your home screen or in a folder labeled “Utilities.”
Tap to open the app. You’ll see a variety of options, including My Watch, Face Gallery, and App Store. Make sure you’re on the My Watch tab at the bottom.
Step 2: Navigate to Passcode Settings
Scroll down the My Watch screen until you find the Passcode option. Tap on it to enter the passcode settings menu. Here, you’ll see options like “Turn Passcode On/Off,” “Change Passcode,” and—most importantly—“Unlock with iPhone.”
Step 3: Toggle Off “Unlock with iPhone”
Look for the Unlock with iPhone toggle switch. When this is enabled (green), your Apple Watch will automatically unlock whenever your iPhone is unlocked and in close proximity. To disable auto unlock, simply tap the toggle to turn it off (it will turn gray).
Once disabled, your Apple Watch will no longer unlock automatically. You’ll need to enter your passcode manually each time you put the watch on or wake it up after it’s been locked.
Step 4: Confirm Your Changes
After turning off the feature, exit the Watch app and test it out. Lock your iPhone, then try to use your Apple Watch. It should now require a passcode to unlock—even if your iPhone is nearby and unlocked.
Pro Tip: If you ever want to re-enable auto unlock, just follow the same steps and toggle the switch back on. Apple makes it easy to switch between convenience and security as your needs change.
Troubleshooting Apple Watch Auto Unlock Issues
Sometimes, users report that the “Unlock with iPhone” option is grayed out or unavailable. This usually happens for one of two reasons:
- Your iPhone passcode is turned off: Auto unlock requires both devices to have a passcode. Go to Settings > Face ID & Passcode (or Touch ID & Passcode) on your iPhone and make sure a passcode is set.
- Your Apple Watch passcode is disabled: If your watch doesn’t have a passcode, the auto unlock feature won’t appear. Return to the Watch app > Passcode and enable a passcode first.
If the toggle still won’t respond, try restarting both your iPhone and Apple Watch. Hold the side button and Digital Crown on the watch until the power-off slider appears, then restart. On the iPhone, hold the side button and volume button until the slider appears.
How to Remove Auto Unlock from Wear OS Smart Watches
Wear OS, developed by Google and used by brands like Fossil, TicWatch, and the Google Pixel Watch, offers a similar auto unlock feature. However, the process to disable it is slightly different and involves the Wear OS app on your Android phone.
Step 1: Open the Wear OS App on Your Android Phone
Unlock your Android phone and locate the Wear OS by Google app. If you don’t see it on your home screen, check your app drawer or search for “Wear OS” in the Play Store.
Tap to open the app. Make sure your smart watch is connected and synced. You should see your watch’s name and battery level at the top of the screen.
Step 2: Access Watch Settings
Tap on your watch’s name or the gear icon (Settings) to enter the device settings. This will bring up a menu with options like Notifications, Sound, Display, and Security.
Step 3: Find and Disable Auto Unlock or Smart Lock
Look for a section labeled Security or Lock Screen. Depending on your watch model and Wear OS version, the exact wording may vary. You might see options like:
- “Auto unlock”
- “Smart Lock”
- “Trusted face” or “Trusted voice”
- “Wrist detection”
Tap into the relevant setting. For example, if you see “Auto unlock,” tap it. You’ll likely be taken to a screen that explains the feature and shows a toggle switch.
Turn off the toggle to disable auto unlock. Some devices may also have a “Wrist detection” feature that keeps the watch unlocked while you’re wearing it. While not exactly the same as auto unlock, it can reduce security. Consider disabling this as well if privacy is a top concern.
Step 4: Set a Strong Passcode or PIN
After disabling auto unlock, make sure your watch is protected with a secure passcode, PIN, or pattern. Go back to the Security section and select “Set passcode” or “Change passcode.” Choose a code that’s hard to guess but easy for you to remember.
Avoid simple codes like “1234” or “0000.” Instead, use a mix of numbers or a pattern that’s unique to you.
Step 5: Test the Changes
Lock your phone and watch, then try to wake up your smart watch. It should now prompt you to enter your passcode—even if your phone is nearby and unlocked.
Pro Tip: Some Wear OS watches also support biometric unlock methods like face recognition or voice match. While convenient, these can be less secure than a passcode. If you’re serious about security, stick to a traditional PIN.
Troubleshooting Wear OS Auto Unlock Issues
If you can’t find the auto unlock setting, it may be because:
- Your phone’s Smart Lock is enabled: Android’s Smart Lock feature can keep your phone unlocked in trusted locations or when connected to trusted devices. Go to Settings > Security > Smart Lock on your Android phone and disable any options related to your watch.
- Wear OS app needs an update: Open the Google Play Store, search for “Wear OS,” and check for updates. An outdated app may not show all settings.
- Watch firmware is outdated: On your watch, go to Settings > System > About > Versions > check for system updates. Install any available updates to ensure full compatibility.
If the issue persists, try unpairing and re-pairing your watch through the Wear OS app. This resets the connection and often resolves syncing problems.
How to Remove Auto Unlock from Samsung Galaxy Watch
Samsung Galaxy Watch models (including Galaxy Watch 4, 5, 6, and Active series) use the Galaxy Wearable app to manage settings. The auto unlock feature is tied to Samsung’s ecosystem and can be disabled through the app.
Step 1: Open the Galaxy Wearable App
On your Android phone, open the Galaxy Wearable app. If you don’t have it, download it from the Google Play Store. Make sure your Galaxy Watch is connected via Bluetooth.
Step 2: Go to Watch Settings
Tap on your watch’s name at the top of the screen to access its settings. You’ll see a list of categories like Notifications, Sounds, Display, and Lock screen.
Step 3: Disable Auto Unlock in Lock Screen Settings
Tap on Lock screen. Here, you’ll find options such as:
- “Auto unlock”
- “Unlock with phone”
- “Smart unlock”
Tap on the relevant option and toggle it off. On some models, you may also see “Wrist detection” or “Keep watch unlocked.” Disable these if you want maximum security.
Step 4: Set a Secure Lock Method
After disabling auto unlock, ensure your watch is protected. In the same Lock screen menu, select “Set lock type” and choose a passcode, PIN, or pattern. Avoid using simple combinations.
Samsung also offers biometric options like fingerprint scanning (on supported models) or iris scanning. While convenient, these may not be as secure as a strong passcode—especially if someone has access to your fingerprint or face.
Step 5: Confirm and Test
Exit the app and test your watch. Lock your phone and watch, then try to use the watch. It should now require manual authentication.
Pro Tip: If you use Samsung Pay or other secure apps on your watch, keeping auto unlock disabled ensures that no one can access them without your passcode—even if they have your phone.
Troubleshooting Galaxy Watch Auto Unlock Issues
If the auto unlock toggle is missing or grayed out:
- Check if your phone has a lock screen: Auto unlock requires both devices to have a lock method. Go to Settings > Lock screen on your phone and set a PIN, pattern, or password.
- Update the Galaxy Wearable app: Open the Play Store, search for “Galaxy Wearable,” and install any updates.
- Restart both devices: Power off your phone and watch, wait 30 seconds, then turn them back on and reconnect.
If problems continue, consider resetting your watch to factory settings (Settings > General management > Reset). Note: This will erase all data, so back up first.
General Tips for Securing Your Smart Watch
Disabling auto unlock is a great first step, but true security involves a few extra precautions. Here are some best practices to keep your smart watch safe:
- Use a strong, unique passcode: Avoid birthdays, phone numbers, or repeating digits. Aim for at least 6 digits or a complex pattern.
- Enable two-factor authentication (2FA): For apps like Google, Apple, or Samsung accounts, use 2FA to add an extra layer of protection.
- Keep software updated: Regularly update your watch’s firmware and your phone’s operating system to patch security vulnerabilities.
- Disable unnecessary features: Turn off Bluetooth, Wi-Fi, or NFC when not in use to reduce attack surfaces.
- Monitor app permissions: Review which apps have access to your watch’s sensors, location, and notifications. Revoke access for apps you don’t trust.
- Use Find My Device features: Enable tracking options like “Find My iPhone” or “Find My Mobile” so you can locate or remotely lock your devices if lost.
When You Might Want to Re-Enable Auto Unlock
While we’ve focused on removing auto unlock for security, there are times when it makes sense to turn it back on—especially if convenience outweighs risk.
For example, if you’re at home and your devices are in a secure environment, auto unlock can save time. It’s also useful during workouts when you want quick access to fitness apps without fumbling with a passcode.
Just remember: auto unlock should be disabled in public or high-risk situations. Consider making it a habit to toggle the feature on and off based on your location and activity.
Some users create routines or use automation apps (like Shortcuts on iPhone or Tasker on Android) to disable auto unlock when leaving home and re-enable it upon return. This balances security and convenience.
Conclusion
Removing auto unlock from your smart watch is a simple but powerful way to enhance your digital security. Whether you use an Apple Watch, Wear OS device, or Samsung Galaxy Watch, the steps are straightforward and well worth the effort.
By disabling this feature, you prevent unauthorized access, reduce the risk of data breaches, and gain greater control over your personal information. And with the added peace of mind that comes from knowing your devices are locked down, you can enjoy all the benefits of your smart watch without the hidden risks.
Remember to pair this change with strong passcodes, regular updates, and smart privacy habits. Your smart watch is more than a gadget—it’s a gateway to your digital life. Protect it wisely.
