Clean the Scanner

The very first thing to do if your iPhone’s touch ID is not working is cleaning the scanner. This is used to detect the high-resolution picture of your finger, reads your fingerprints and then matches it with the fingerprint stored in the file.
As the sensor or scanner is very much sensitive thing, so it detects anything over it even if it is very tiny in size or low in weight. When there are dust or dust particles over it, it will be unable to read the fingerprints and understands the structure of the dust particles, which alternatively does not unlock the screen, and you will think that the touch ID is not working.
So, clean correctly and then try. If the problem was only occurring because of dust, then the scanner will start working after cleaning it.
