Changing a Fitbit Air band takes about 30 seconds and no tools. You push the small screenless tracker out of the old band, press it into the new band from below until it clicks, and double-tap to confirm it is seated. Google describes the same steps in its official setup guide, and they work for every Fitbit Air band in our store, including the bicep armband.

What do you need to change a Fitbit Air band?
- Your Fitbit Air tracker (the small pill-shaped "pebble").
- The new band, made for Fitbit Air.
- Dry hands and about half a minute.
Step 1: Hold the band either side of the tracker
Take the band off your wrist. Pinch the outside edges of the band right next to where the tracker sits, so the band frame cannot bend away while you push.
Step 2: Push down on top of the tracker to pop it out
Press firmly on the top of the tracker with your thumb. It pops out through the underside of the band. Google's guide puts it simply: hold the band next to the device and push firmly on top of the device to pop it out.
Step 3: Press it into the new band from below
Turn the new band so its frame faces you. Line up the small alignment marks on the tracker and the band, then press the tracker in from below until it snaps into place. You should feel a click.
Step 4: Double-tap to check it is seated
Firmly double-tap the top of the tracker. If the light flashes, the tracker is seated correctly and you are ready to wear it.
What if the light does not flash?
- Take the tracker out and press it back in, making sure it clicks.
- Rotate the tracker so the small alignment marks line up, then try again. Google recommends this as the main fix.
- Check that the band frame is free of lint, sweat or sand.
- If the battery is flat the tracker may not respond, so charge it and try once more.
Tips if you swap bands often
- Keep the frame clean. A quick rinse and full dry stops grime building up where the tracker sits. See how to clean a Fitbit Air band.
- Match the band to the day. A ribbed silicone sport band for sweaty workouts, a nylon sport loop for everyday comfort and a slim woven band with metal case for work.
- Save on a set. Our combo offers let you pick any two or three straps for one lower price.
