Andrew, just because the part is available does not mean that it can be replaced without sequela. The touch ID sensor is designed to be secure and it is uniquely paired with each specific phone. There is no way to restore that particular function. Read more about that [http://www.etradesupply.com/blog/iphone-5s-touch-id-repair-problems/|on here.] and on here [http://9to5mac.com/2013/10/31/the-inner-workings-of-touch-id-each-fingerprint-sensor-is-paired-to-a-specific-a7-chip/|as well.] "unique logic board in each iPhone 5S and the fingerprint data is stored '''on the A7 chip'''" I am with Tom and con, don't do it. Hope this helps, good luck.
