Introduction
Use this guide to replace the antenna bar in your MacBook Pro 16" 2021.
'''For your safety, discharge the battery below 25% before disassembling your phone.''' This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]].
Conclusion
To reassemble your device, follow these instructions in reverse order.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
