Old home button was replaced due to a torn ribbon, however I can’t get the new one to work at all
Home button won’t ever work if replaced on iPhone 7 and above. There are 3rd party reprogrammable buttons, but they are just buttons, it is impossible to repair Touch ID feature.
you need an aftermarket button, an ebay special from japan will usually work and are inexpensive. genuine ones will never work unless apple install one for you at £300 upwards and sync it to the device. and aftermarket one will work just with passcode.
