iPhone SE (2020) Touch ID fails after battery replacement

Hi there everyone 😊

Do please let me know if you might be able to suggest a solution here.

I have a iPhone SE (2020). A couple days ago I had the battery replaced at a local tech support. The old battery was at 74% capacity and the new one at 100 %.

However, soon after the replacement my Touch ID (one thumb print) stopped working. Now I am blocked from several things such as doing a system reset that requires Touch ID. I can also no longer update my passcode. I keep getting a message that because I have “Stolen Device Protection” turned on, then a number of features are unavailable, for example adding another finger for Touch ID. I reached out to Apple support chat (live agent) who did troubleshooting and said my phone needs to be serviced.

If possible I would love to hear if anyone here has had this problem and seen a successful way of remedying it.

thanks so much in advance

I recommend that you take the iPhone back to your local tech store that replaced your battery and ask them whether they can help in the matter. If they can’t help you, then below is what I discovered:

Touch ID stops working after a battery replacement when the Home button’s original pairing to the logic board is disrupted. Once that happens, Touch ID cannot be restored by software, resets, or troubleshooting. Because Stolen Device Protection is on, the phone also blocks changes to Touch ID and passcode until the hardware is verified.

The only fix is to have Apple or an Apple‑authorized repair center replace the Home button assembly or service the device. Third‑party shops cannot restore Touch ID once the pairing is broken.

Hello Susanisherenow,

If the repair shop is not a Certified Apple Repair Shop, then Touch ID will be disabled as a 3rd party repair shop is unable to verify parts when they do repairs. You will need to get in contact with them to see what they did exact with your phone as this is not normal.

Sincerely,

Captain
