Why Won’t Your Fitbit Band Snap-On?

If you change the bands on your device, you should ensure that they attach properly to the tracker. You will hear a clicking sound to confirm the same. However, if you do not hear the sound even after moving the band around, you might be dealing with two scenarios:

A problem with the band

This is a common issue, and it could be because your band has worn out at the edges. It could also be because your band is dirty. So, the first thing you should do is to gently clean your band. This will ensure that any dirt on the band that is preventing its attachment gets removed. If your band still does not fit, you might have a deeper issue with the band. In this situation, it is best to change or replace the band altogether.

A problem with the tracker

If changing the band does not do the trick, your track would most likely have a problem. It could be a problem with the clasping mechanism of your tracker. It could even be a problem in the design. Whatever the problem is, you would not be able to fix it yourself. You should take it to an expert instead.


For most Fitbits, changing their bands is not difficult. Hope you got some insight into changing the band of your device. That said, in case you face any confusion, you must refer back to the steps or consult an expert.
