lost button on side, is it repairable?

"freakyc, Replacemnt vid. link and possible replacement part below. You can also contact fitbit especially if under warranty or not, as a lot of people have had the same fault and they may value you as a customer and make things right(fit bit support last link). Good luck. I hope this helped you out, if so let me know by pressing the helpful button.

The device is out of warranty I assume, but there are replacement guides online. However, I was unable to find a replacement part. Sorry I couldn't help more. Good luck!
