The assembly is briskly snappedinto place. You'll need to separatethe sides of the housing with a smallplastic tool and your finger nail (ortwo plastics). Be careful, as thehousing can fracture with too muchforce.

Once removed, there are 2 torx screws holding the circuit board in place. Remove these, andcarefully pry the board out

Stap 7 — Prepare to solder!

The Fitbit is very light, and hard to hold, so I recommend taping the board in place when soldering.

Stap 8 — Understand the risk to your device.

Note: You can permanently damageyour device. Be careful with theassembly, and splice one or bothwires before removing the oldbattery to prevent a short. Do notmistake the round buzzer for abattery. It is not !
