Our take on the Fingerprint Door Lock, Smart Fingerprint Door Knob with Keypad

This is a keyless door knob that unlocks by fingerprint or keypad code, with an auto-lock function and a rechargeable battery. It is a budget retrofit for a standard interior or entry door rather than a full smart deadbolt. At $31.99 at Amazon as of November 4, 2026, it sits at the low end of its recent price range, and three stores list it new.

Questions and answers

Is this lock a good choice for a front door?
Only as a secondary lock. It is a knob, not a deadbolt, so it offers less forced-entry resistance than a rated deadbolt. Use it on interior doors or alongside a deadbolt on an entry door.
How many fingerprints and codes can it store?
Listings for this class of knob typically support several fingerprints and multiple user codes, with admin codes to add or remove users. Check the seller's spec sheet for the exact count before buying.
How is it powered and how long does the battery last?
It has a rechargeable battery, so there are no AA cells to swap. Runtime depends on how often the motor and reader run; expect to recharge every few months in normal household use.
Does it fit a standard door?
It is designed for standard door prep, but knob locks vary in backset and door thickness range. Measure your door thickness and backset and compare to the listing before ordering.
Is $31.99 a good price?
It is the lowest new price among the three stores listing it as of November 4, 2026, and sits at the bottom of its recent range. At this level the difference between stores is small, so buy from the store with the better return policy.
