Troubleshooting Unloc on Apple Watch
This guide helps you resolve common issues with the Unloc app on your Apple Watch.
Doors not appearing on watch
If you don't see your doors on the watch app:
Check that the door is a favorite
Only favorite doors appear on your watch. On your iPhone:
- Open the Unloc app
- Find the door
- Make sure the star icon is filled (marked as favorite)
Trigger a sync
Open the Unloc app on your iPhone. This prompts a sync with your watch. Keep both devices nearby for a few moments.
Check device pairing
Make sure your Apple Watch is properly paired with your iPhone:
- Open the Watch app on your iPhone
- Verify your watch appears as connected
- Check that Bluetooth is enabled on both devices
Verify lock support
Some lock types are not supported on Apple Watch due to technical limitations. If a specific door doesn't appear despite
being a favorite, the lock type may not be compatible with watchOS.
"Needs internet" message
This message appears for IP-operated locks when your watch cannot reach the internet.
Check watch connectivity
- Open Settings on your Apple Watch
- Tap WiFi and verify you're connected to a network
- If using cellular, check that mobile data is enabled
Move closer to your iPhone
If your watch relies on your iPhone for internet, make sure your phone is nearby and connected to the internet.
Try toggling WiFi
Sometimes reconnecting helps:
- Open Settings on your watch
- Tap WiFi
- Toggle WiFi off, wait a few seconds, then toggle it back on
Check cellular data (if applicable)
If your watch has cellular:
- Open Settings on your watch
- Tap Cellular
- Verify your plan is active and data is enabled
Lock not responding
If you tap Open or Close but nothing happens:
For Bluetooth locks
Get closer to the lock
Bluetooth range is limited. Stand within 2-3 meters of the lock and try again.
Check Bluetooth is enabled
- Open Settings on your watch
- Tap Bluetooth
- Make sure Bluetooth is on
Check for obstructions
Walls, metal doors, and other obstacles can weaken Bluetooth signals. Try standing directly in front of the lock.
For IP locks
Verify internet connection
IP locks require your watch to have internet access. Check your connection as described above.
Check connection stability
If your connection is weak or unstable, the command may not reach the lock. Try:
- Moving to an area with better signal
- Switching between WiFi and cellular
- Toggling WiFi off and on
Wait and retry
Network delays can cause timeouts. Wait a moment and try the operation again.
Keys showing as expired
When a Bluetooth lock's key has expired, you need to refresh it.
Connect to the internet
Key refresh requires an internet connection. Ensure your watch can reach the internet via WiFi, iPhone, or cellular.
Refresh the key
- Tap the status icon (red info icon) on the door
- Read the status message confirming expiration
- Tap "Refresh" to download new key data
- Wait for the refresh to complete
If refresh fails
- Check your internet connection
- Try moving closer to your iPhone
- Toggle WiFi off and on
- Wait a moment and try again
Watch not syncing with iPhone
If changes on your iPhone don't appear on your watch:
Keep devices close together
Syncing uses Bluetooth. Make sure your iPhone and Apple Watch are within range of each other.
Enable Bluetooth on both devices
- On iPhone: Settings > Bluetooth > On
- On Apple Watch: Settings > Bluetooth > On
Open the app on both devices
Opening Unloc on your iPhone triggers a sync. You can also open the app on your watch to receive pending updates.
Restart both apps
- On your watch, press the side button to see recent apps
- Swipe left on Unloc and tap the X to close it
- On your iPhone, swipe up from the bottom (or double-tap home) and swipe away Unloc
- Reopen both apps
Restart your devices
If syncing still doesn't work:
- Restart your Apple Watch (hold side button > Power Off > turn back on)
- Restart your iPhone
- Open Unloc on both devices
Operation succeeds but door doesn't open
If the app shows success but the physical door doesn't unlock:
Try again
Occasionally the command succeeds on the app side but doesn't reach the lock. Try the operation once more.
Check the lock hardware
- Make sure the lock has power (battery or wired)
- Look for any indicator lights on the lock
- Check if the door is jammed or obstructed
Verify your access
Your key may have restrictions:
- Time-based access (only valid during certain hours)
- Date restrictions (expired access period)
- Contact the person who shared the key with you if unsure
Poor network quality warnings
If you see warnings about unstable connections:
Improve your connection
- Move to an area with better signal
- Connect to a different WiFi network
- Move closer to your iPhone
Toggle WiFi
Switching WiFi off and back on can help establish a better connection:
- Open Settings on your watch
- Tap WiFi
- Toggle off, wait 5 seconds, toggle on
Use a different connection method
If WiFi is unstable, try:
- Moving closer to your iPhone to use its connection
- Enabling cellular data if your watch supports it
App crashes or freezes
If the Unloc app becomes unresponsive:
Force close and reopen
- Press the side button to show recent apps
- Swipe left on Unloc
- Tap the X to close it
- Reopen the app from your home screen
Restart your Apple Watch
- Press and hold the side button
- Tap Power Off
- After the watch turns off, press and hold the side button to turn it back on
Reinstall the app
If problems persist:
