If your Fitbit Charge 2 is stuck and you need to open it, there are a few steps you can take. Firstly, ensure your Fitbit is off the charger and powered down. Then, remove the watch band on both sides. Next, heat an iOpener and apply it to the touch screen for two minutes. This helps to loosen the touch screen assembly. Once done, insert an iSesamo into the gap between the touch screen and the watch assembly, starting from the top left corner. Slide the iSesamo around the edges of the screen until you reach the top right corner. Finally, pry up the touch screen assembly by twisting the iSesamo sideways to unhinge the plastic clips holding the screen in place.

What You'll Learn
Remove the watch band
To remove the watch band from a Fitbit, you will need to identify the type of Fitbit you have, as the process can vary.
For the Fitbit Ace 3 and Ace 2, the process is simple. Hold the watch case so that the button is on your left. Gently press the watch case through the opening on the flexible band to remove it.
The Fitbit Ace, Alta, and Alta HR have a slightly different process. Turn the tracker over and find the band latches—there is one on each end where the band meets the frame. To release a latch, press down on the flat metal button on the strap. Slide the band up to release it from the tracker. Repeat on the other side.
The Fitbit Sense, Sense 2, Versa 3, and Versa 4 also have detachable bands. Turn over your watch and find the band latches. To release the latch, slide the flat button toward the band. Gently pull the band away from the watch to release it. Repeat on the other side.
The Fitbit Versa, Versa Lite Edition, and Versa 2 have a quick-release lever. To remove the band, turn your watch over and find this lever.
For the Fitbit Charge, Ionic, Inspire, and Ace, hold the watch case in one hand and press the metal button with the thumbnail of your other hand. Gently detach the band by pulling it out. It should come off easily when you press the button. Repeat for the other side.
If your Fitbit band is stuck and you are having trouble removing it, gently move the band back and forth to release it. Do not force it. If you continue to have problems, contact Fitbit's support team for further assistance.
In some cases, you may need to use tools to remove a stuck band. For example, if a piece of the band is stuck in the slot, you may be able to use tweezers or a kitchen paring knife to carefully remove it.

Loosen the touch screen assembly
Firstly, power down your Fitbit and remove the watch band on both sides. Then, heat an iOpener and apply it to the touch screen for about two minutes. The screen is not glued down, but the heat will help to loosen the touch screen assembly.
Next, insert an iSesamo into the gap between the touch screen and the watch assembly, starting at the top left corner. Slide the iSesamo along the left edge to the bottom left corner, and then around to the bottom right corner. You can then slide it along the bottom edge to the right corner.
Now, you can pry up the touch screen assembly by twisting the iSesamo sideways to create a gap. Insert a spudger into this gap and use it to carefully pry up the touch screen assembly. Be careful not to remove the touch screen assembly completely, as it is still connected to the motherboard.
Finally, fold the touch screen assembly towards the bottom edge of the Fitbit. You can now proceed with your desired repairs or replacement. Remember to be gentle and careful throughout the process to avoid any accidental damage to the internal components of your Fitbit.

Pry up the touch screen assembly
To pry up the touch screen assembly of your Fitbit Charge 2, follow these steps:
Firstly, power down your Fitbit and remove the watch band on both sides. Next, heat an iOpener and apply it to the touch screen for two minutes. The screen is not glued down, but the heat will help loosen the touch screen assembly.
Now, insert an iSesamo into the gap between the touch screen and the watch assembly, starting at the top left corner. Slide the iSesamo along the left edge to the bottom left corner, and then continue sliding it along the bottom edge to the bottom right corner. Keep sliding the iSesamo along the right edge to the top right corner, and then along the top edge back to the top left corner.
At this point, you can reattach the watch band to gain a better grip for the next step. Place the iSesamo under the top left corner and twist it sideways to create a gap. Pry up the touch screen assembly by twisting the iSesamo further to unhinge the plastic.
Once you have pried up the touch screen assembly, you can proceed to remove it by carefully folding it towards the bottom edge. Be cautious and gentle throughout this process to avoid causing any damage to the internal components of your Fitbit.

Reassemble the device
To reassemble your Fitbit device, you will need to follow the disassembly instructions in reverse order. Here is a detailed guide on how to do this:
Firstly, you will need replacement adhesive to reattach the components when reassembling the device. Before you begin, ensure your Fitbit is powered down and removed from the charger. You can attach or remove the watch band as needed to provide more control as you make repairs.
Next, clean the relevant areas of the device with isopropyl alcohol (>90%). After cleaning, apply new adhesive where necessary. Compare your new replacement part to the original part, and transfer any remaining components or remove adhesive backings from the new part before installing.
Now, carefully fold the display assembly back to its original position. Reinsert the two Torx T2 screws (3.65 mm length) into the top edge of the watch. Use tweezers to secure the metal cover in place.
Use a spudger to reconnect the NFC antenna and the two display cables to the motherboard. Finally, secure the display assembly in place. If possible, turn on your Fitbit and test your repair before installing new adhesive and resealing the device.
By carefully following these steps in reverse, you can successfully reassemble your Fitbit device.
