Touch ID not working on original Homebutton

Could I ask you a question please.

I have an iphone 6 and bought a new screen which included a pre fitted home button and camera. I swapped over my original home button which did work with the touch ID. I added it to the new screen and when I put it back together the touch ID no longer works. Everything else is fine though.

There are no error codes. I have tried turning the power off, disconnecting battery and the home button then reconnecting it all again.

As i said, everything works fine but no touchID.

Can anyone help please.

Swap the home button extension cable Metal plate and see if that works.


I have seen this problem on ifixit before and people have said that updating to the latest ios has resolved the issue.

There are three areas you need to inspect with either a magnifying glass or jeweler's loupe.

  1. Where the home button connects to the logic board along with the LCD, Digitizer and Camera.
  2. Underneath the shield plate under the Home button, the Home button connects with the Home button extension flex that runs under the LCD heat shield.
  3. The tiny circuitry on the Home button flex itself as well as the integrity of the flex between the button and the circuitry.

The connectors at either end of a flex, as well as on the logic board, are very delicate and can be damaged very easily. Check for broken pins or debris that may impede contact. Also, the flex on the Home button tears very easily so look for tears or deep scratches. Finally, because you have to peel of the button flex, look for damage in the area where the electronics components reside.

Always disconnect the battery. It should be the first and last step whenever you open your phone.
