Here we offer you a new button for your iPhone SE.
This original replacement part for Apple iPhone SE Home Button Assembly can support all the basic functions except for unlocking the iPhone with fingerprint.
As Apple has already stated that fingerprint data is stored on the A7 chip in a Secure Enclave that is only accessible by the sensor itself, the Touch ID sensor is tied to the unique logic board inside each iPhone. If you break the original Touch ID sensor then that iPhone 6 you need to unlock the iPhone in order to install the new sensor.
Not usable for the any other iPhone than 5S/SE
