The Itopfox Keypad Door Knob 4-in-1 is a smart knob lock that opens four ways: keypad code, fingerprint, app control and a physical key. It fits standard door prep and replaces an ordinary knob, so renters and homeowners can add keyless entry without a deadbolt. Against deadbolt-style smart locks it is simpler to install but offers less physical security, since a knob latch is easier to defeat than a deadbolt. Buyers who want app control and fingerprints on an interior or light-duty door get those features here; those securing an exterior entry should weigh it against a deadbolt lock.
