Hi there, @Veena89. Welcome to the Fitbit Community Forums. I'm sorry to hear that you cannot unlock your Versa 2 as it's no longer paired from your phone. I'll do my best to get you back on track.
With that being said and in order to unlock the watch now that it's no longer paired to your phone, I suggest to perform a factory reset by following these steps:
- Hold the back button for about 8 seconds.
- When the Fitbit logo disappears:
- Release the button briefly (for less than 2 seconds).
- 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.
Let me know how it goes.
