How does the Nuk D500 unlock?

It reads a stored fingerprint on the knob and releases the latch. There is no keypad and no key cylinder, so entry depends on an enrolled finger.

Does it work with a phone app?

No. The D500 has no app, Wi-Fi or Bluetooth, so you cannot unlock it remotely or issue temporary codes.

It is a knob, not a deadbolt. On an exterior door, pair it with a separate deadbolt for real security.

It runs on batteries, so plan on replacing them periodically and keeping a backup way in.

It is designed for standard door prep, but check your door thickness and backset before buying.
