The chip that stores data and is paired with the CPU is "printed" on the back of the home button itself.

It is not on the flat cable like it used to be for the iPhone 5s.

It is literally impossible to remove and transfer it without destroying it in the process.

Is it possible to replace the flat cable? If so, can you point me to a guide?

That's actually got me curious also. So lemme get this straight. You could remove the chip on the cable, and transfer the Touch ID, to a different button?

@theimedic for the 5S, you can transfer the chip.

For the iPhone 6 and newer, the chip is embedded on the back of the home button in such a way that you cannot transfer it without breaking it. The best you could do is rewire the home button in case the cable is broken. It is a lot of work and rarely worth the effort. But it has been done.

As for the whole flat home button flat cable, you can buy an after market one or transfer one from a donor phone. In Either case, Touch ID function will not work for iPhones 5S and newer. And for the iPhone 7/7+, nor Touch ID function nor home button function. Once it goes bad or is replaced, that button for the 7/7+ becomes completely unresponsive to any kind of input and does not serve any purpose except plug a hole in the screen.

@bullschlitz here's a guide for replacing the home button flex cable.

Rany is right. The answer is no. But you can go to Apple for a new screen which will come with a new home button. They withold access to their fingerprint sensor/touch ID pairing machine, but they are able to pair the new button to the device in house at some Apple Stores.
