Symptoms
You might be experiencing this problem if you notice:
- •PC doesn't lock after walking away with paired phone

- •Dynamic Lock works intermittently — sometimes locks, sometimes not
- •Bluetooth device disconnects but PC never locks
- •Dynamic Lock stopped working after Windows Update
- •"Dynamic lock isn't working" warning in Settings
Common Causes
- ⚠Bluetooth signal range too strong (PC still "sees" device far away)
- ⚠Dynamic Lock has built-in 30-second delay by design
- ⚠Bluetooth pairing degraded or device not connecting properly
- ⚠Bluetooth power management putting adapter to sleep
- ⚠Dynamic Lock feature not properly enabled
- ⚠Bluetooth driver outdated or buggy
Solutions
Solution 1: Configure Dynamic Lock Properly
- 1Enable Dynamic Lock:
- 2Settings → Accounts → Sign-in options
- 3Scroll to "Dynamic lock"
- 4Check "Allow Windows to automatically lock your device when you're away"
- 5Note: Dynamic Lock has a built-in ~30 second delay
- 6This is by design to prevent false locks when phone briefly disconnects
- 7Ensure your phone is paired via Bluetooth:
- 8Settings → Bluetooth & devices → Add device → Bluetooth
- 9Pair your phone — it should show as "Connected" or "Paired"
Solution 2: Fix Bluetooth Connection
- 1Dynamic Lock requires a stable Bluetooth connection:
- 2Remove and re-pair your phone:
- 3Settings → Bluetooth & devices → find your phone → Remove device
- 4On your phone: forget the PC from Bluetooth settings too
- 5Re-pair: Settings → Bluetooth & devices → Add device → Bluetooth
- 6Fix Bluetooth power management:
- 7Device Manager → Bluetooth → your Bluetooth adapter → Properties
- 8Power Management → UNCHECK "Allow the computer to turn off this device"
- 9Update Bluetooth driver:
- 10Right-click adapter → Update driver → Search automatically
Solution 3: Reduce Lock Delay
- 1The default 30-second delay cannot be changed in Settings
- 2Registry tweak to reduce delay (advanced):
- 3This requires modifying Task Scheduler:
- 4Task Scheduler → Task Scheduler Library
- 5Look for "Dynamic Lock" related tasks
- 6The polling interval determines how often Windows checks
- 7Alternative: use a third-party auto-lock tool for faster locking
- 8Ensure phone Bluetooth stays on and discoverable
- 9Low battery mode on phones often disables Bluetooth — keep charged
- 10If nothing works: screen saver with password is a reliable alternative
- 11Settings → Personalization → Lock screen → Screen timeout settings
