Fingerprint Door Lock

At a bedroom or home-office door, a keypad and fingerprint reader can make entry less dependent on finding a key while keeping a mechanical backup available. This smart door lock offers fingerprint, passcode, app control, and two traditional keys, so you can choose a method that fits the moment rather than relying on one type of access.

If you prioritize quick keyless entry, the fingerprint reader and illuminated keypad are the main draw, if you prefer a familiar fallback, the included keys are there too. It’s a great fit if you want several ways to open an interior door without adding a separate deadbolt.

Where it shines

The mix of access methods is useful in everyday situations. For example, you could unlock the door with a fingerprint when you come back to a home office with your hands full, then share a one-time passcode with a guest who needs temporary access. The anti-peep keypad feature is intended to make entering a code less exposed to someone nearby, while the backlit buttons help when the room or hallway is dim.

There are also settings for different routines: silent mode turns off lock sounds, and passage mode keeps the door unlocked when you want it to remain open. Those options make this more adaptable than a basic keyed knob, though they also mean it is worth learning which mode is active before relying on the lock for privacy.

Highlights

The product description lists four entry methods: fingerprint, passcode, app control, and two mechanical keys. It advertises fingerprint recognition in 0.2 seconds and says the lock can open in one second, treat those as maker-provided figures, not a guarantee for every finger or situation. A low-battery alert is included, and the rechargeable 400mAh battery is said to take 4–6 hours to charge and provide up to a full year of standby power, according to the maker. Actual battery life may depend on use, and the mechanical keys offer a backup if electronic access is unavailable.

Installation is described as a no-drill, single-screwdriver DIY job, with an estimated 15-minute setup. Fit matters more than that estimate: the adjustable latch is listed for 2-3/8" or 60mm to 2-3/4" or 70mm, and the door thickness range is 1-1/8" to 2-1/8" (30mm–55mm). If your door falls outside those dimensions, this model may not suit it. The listing also states a 12-month warranty and lifetime technical support.

Best use cases

This setup makes the most sense for a bedroom or home office where several entry methods are useful and the door matches the stated US door measurements. A temporary code can be handy for a planned visit, while fingerprint or passcode access avoids carrying a key for routine entry. It’s not for you if you need a lock for a door that does not match the listed dimensions, or if you want detailed information about app compatibility or a particular smart-home ecosystem, those details are not provided here.

When it makes sense

Choose this knob if you want keyless access, a physical-key backup, and settings such as passage and silent mode in one door lock. Compared with a simpler keyed knob, it adds more entry options and guest-code flexibility, but also introduces a rechargeable battery and electronic features to manage. If straightforward keyed entry is all you need, that extra setup may not add much. For a suitable bedroom or home-office door, the deciding checks are the latch and thickness measurements—and whether the listed access methods match how you expect to use the room.
