Why People Are Switching to This Fingerprint Deadbolt

Most smart locks give you two or three ways in — fingerprint, code, maybe an app. The Tapo DL110 gives you six: fingerprint recognition, a keypad passcode, WiFi app control from anywhere, close-range Bluetooth, your smart home voice assistant, and a set of included physical backup keys. That redundancy is the actual selling point — if your phone dies, your fingerprint sensor is wet from rain, or WiFi is down, you still have at least one other way to get inside, rather than being stuck troubleshooting a single point of failure at your own front door.

The fingerprint sensor itself is rated for 0.42-second recognition and can store up to 100 different fingerprints, and the lock is built for real household management: you can create permanent resident profiles for family, or set up one-time or scheduled codes for guests, a dog walker, or a cleaner — each tracked separately rather than everyone sharing one master code.

What Owners Actually Say

At 4.6 stars across 815 ratings, this is both a high rating and a meaningfully large sample size, and Amazon’s own “Overall Pick” designation on the listing reflects that combination directly — it’s not a niche product with a handful of enthusiastic early reviews. TP-Link (Tapo’s parent brand) has an established reputation in smart home hardware generally, which shows up in owners’ comments trusting the WiFi and app reliability more than they might with a newer, unproven brand entering the lock category for the first time.

The Honest Caveats

• BHMA Grade 2 is a solid residential security rating, but it’s a step below the toughest Grade 1 commercial-rated deadbolts — for the vast majority of homes this is more than sufficient, but worth knowing if you’re comparing strictly on lock-grade security ratings rather than smart features.
• Like any WiFi-connected lock, remote unlock and app notifications depend on your home network being up — the Bluetooth and physical key options are there specifically as fallbacks for exactly this scenario, so treat WiFi control as a convenience layer rather than your only access method.
• USB-C charging for the removable battery is convenient, but it does mean you need to physically detach the battery pack to recharge it (roughly once a year per the 1-year battery life spec), rather than it being a fully sealed, zero-maintenance unit.

One Thing to Check Before You Buy

Confirm your door’s deadbolt hole spacing and door thickness are compatible before ordering — like most retrofit smart deadbolts, the DL110 is designed to replace an existing standard deadbolt, so an unusual door thickness or an existing lock with non-standard spacing can complicate a straightforward swap. Amazon’s Q&A section and the product images typically show the standard backset measurements it supports.

How It Compares to a Single-Method Smart Lock

Cheaper fingerprint locks in this category often give you fingerprint plus one backup method — usually a keypad — and call it done. The DL110’s six access methods mean you’re not betting your ability to get inside your own home on one piece of technology working correctly at the moment you need it. For a household where different family members prefer different unlock methods (some people always forget codes, others don’t love touching a shared fingerprint pad), having Bluetooth, WiFi app, voice assistant, keypad, fingerprint, and physical keys all available means everyone can use whichever method they’re most comfortable with, rather than the household being forced into one system.

The Verdict

If redundancy is what you actually want from a smart lock — not being stuck outside because of one dead battery or one forgotten code — the DL110’s six independent access methods make it a genuinely stronger buy than single-method competitors, and the 4.6-star rating across 815 reviews plus the Overall Pick badge back that up with real usage data rather than marketing claims alone.

The 6 Ways to Unlock, Ranked by How Often You’ll Actually Use Them

The Tapo DL110 advertises six separate ways to get through the door: fingerprint, keypad passcode, the Tapo app over WiFi, a physical key, a temporary passcode for guests, and voice-assistant integration. In real daily use, these six sort into a clear hierarchy rather than being six equally-used features. Fingerprint unlock is what most owners default to for themselves and other permanent household members, since TP-Link’s fingerprint sensor on this model has a reputation among reviewers for reading correctly on the first try more consistently than budget competitors, which matters more than any other single spec once you are the one standing at the door with your hands full.

The temporary passcode feature is the standout for anyone who regularly has guests, a cleaner, a dog walker, or a short-term rental situation, because it can be set to expire automatically rather than requiring you to remember to revoke access later. The permanent keypad passcode serves the same role as the fingerprint for people who prefer not to enroll a fingerprint at all, or as backup when hands are wet, gloved, or otherwise unreadable to the sensor. The Tapo app comes into play less for unlocking the door in person and more for checking lock status remotely and reviewing the access log to see who came and went and when.

Voice-assistant unlock through Alexa or Google Home is the feature reviewers use least for actually opening the door, both for security reasons (many households intentionally disable voice-unlock and keep voice control to lock-only) and because it requires being within earshot of a smart speaker rather than at the door itself. The physical key remains the pure emergency backup, worth keeping accessible in case the battery dies or the electronics fail outright. Understanding this hierarchy before buying helps set realistic expectations: most households end up relying on two of the six methods for 90%+ of entries, with the rest available but rarely used.

Frequently Asked Questions

• What is the Tapo DL110 exactly? It’s a WiFi and Bluetooth smart deadbolt with a fingerprint sensor, touchscreen keypad, and BHMA Grade 2 security rating, offering six total ways to unlock your door: fingerprint, keypad code, WiFi app, Bluetooth, voice assistant, and physical backup keys.
• How fast is the fingerprint unlock really? Tapo rates the sensor at 0.42 seconds for recognition, and it can store up to 100 different fingerprints, which is high enough for a large household or a small rental property with rotating tenants.
• How long does the battery actually last? Tapo specifies roughly 1 year of continuous operation on the removable, rechargeable battery before it needs a USB-C recharge, though actual life will vary with how often the lock is used.
• Can I give a dog walker or guest temporary access? Yes — you can create one-time or scheduled access codes for guests separate from permanent resident profiles, so a dog walker or cleaner’s code can be set to expire automatically rather than staying valid indefinitely.
• Does it work if my WiFi goes down? Yes — Bluetooth, the keypad, fingerprint recognition, and physical backup keys all work independently of your home WiFi connection, so a WiFi outage only affects remote app control and notifications, not your ability to get in the door.
• Will it fit my existing door, or does it need a special deadbolt? It’s designed as a retrofit replacement for a standard residential deadbolt, so check your current door’s backset spacing and thickness against the listing’s compatibility details before ordering to confirm a straightforward swap.
