Can't unlock my Sense with my phone

[RoyHof]

I have problems connecting to my Sense. After rebooting my Sense, I try to pair watch with my Android phone. When the pairing code squares come up, the clockface shows "Unlock with your phone". How can I pair my watch?

Hi there, @RoyHof. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Sense. 

As per the description of your post, it seems that your Sense was unpaired from your Fitbit account after the restart you performed. With that being said and in order to unlock the watch now that it's no longer paired to your phone, I suggest performing a factory reset by following these steps:

1. Hold the back button for about 8 seconds. 
2. When the Fitbit logo disappears:
   1. Release the button briefly (for less than 2 seconds). 
   2. Hold the button again until you feel a second, longer vibration, which indicates you initiated the factory reset. 
      
      

At this point you can set up the watch again. For instructions, see How do I set up my Fitbit device? 

Take into consideration that a factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account, your applications, alarms, etc.
