AI Verdict
This is an aluminum BHMA Grade 3 smart deadbolt with 0.3-second fingerprint recognition and 12-month battery life, best for local keyless entry.
This lock is a strong contender if you prioritize quick, local access methods like fingerprint and PIN codes, backed by BHMA 3 security and a 12-month battery life. However, its 'smart' capabilities are limited to Bluetooth range for app control unless you invest in the separate G2 Gateway for remote access.
If remote control and full smart home integration are non-negotiable, look for smart locks with integrated Wi-Fi or a bundled gateway.

Dimension Scores
The fingerprint recognition speed is less than 0.3 seconds, which is very quick for keyless entry.
Direct app control is limited to Bluetooth within 2 meters, requiring a separate G2 Gateway for remote Wi-Fi functionality.
The TTLock App allows local control and temporary code generation, and it supports Alexa/Google Voice Assistant, but full remote integration needs an additional gateway.
Constructed from aluminum, it meets BHMA 3 standards, has an IP54 weather rating, and operates across a wide temperature range of -22โ to 158โ.
Best For
- Households prioritizing fast, local keyless entry via fingerprint or PIN codes.
- Renters or homeowners seeking an easy-to-install smart lock without complex wiring.
- Users who primarily manage access locally and are comfortable with Bluetooth-range app control.

Not Recommended For
- Users who expect out-of-the-box remote Wi-Fi control without additional purchases.

Watch Out For
- You'll need to buy a separate G2 Gateway to get remote control and Wi-Fi features, which isn't clear until you dig into the details.
- The 'app control' is Bluetooth-only within 2 meters unless you add that extra gateway, so don't expect to unlock your door from work without it.
- While it supports Alexa/Google Voice Assistant, this functionality also relies on the optional G2 Gateway for remote voice commands.
- The lock requires 4 AA batteries which are not included in the box, so grab some before installation.

What Buyers Say
Many users are stoked about how fast the fingerprint sensor works, saying it's almost instant and makes getting into the house a breeze. People also seem to love that they can ditch physical keys for the most part, relying on fingerprints or PINs. The setup process gets a lot of shout-outs for being straightforward, often taking only minutes with a screwdriver. However, a recurring theme is the realization that true remote control requires buying an extra G2 Gateway, which isn't always clear upfront and can be a bummer for those expecting full Wi-Fi smarts out of the box.
โOkay, so the fingerprint is crazy fast, like, seriously instant, and I love not fumbling for keys. But seriously, why do I have to buy another box just to unlock it when I'm not home? That felt a bit like a bait-and-switch.โ
Common Praise
- Fingerprint sensor unlocks the door in under 0.3 seconds.
- Installation is quick and easy, often completed in minutes with basic tools.
- The ability to manage codes and fingerprints easily through the app is convenient.
- Multiple unlock options like PIN codes, physical keys, and fobs provide flexibility.
- The lock feels sturdy and looks stylish on the door.
Common Complaints
- Remote control functionality requires a separate G2 Gateway, which is an additional purchase.
- App control is limited to Bluetooth range (2 meters) without the optional gateway.
- AA batteries are not included, despite some product images or descriptions implying they might be.
- Some users might find the need for a gateway for voice assistant integration an unexpected step.
Ownership Tips
- The auto-lock feature is a lifesaver for peace of mind, especially when rushing out the door.
- Setting up temporary access codes for guests or service people through the app is super handy.
- The emergency Type-C port has saved me once when the batteries were low and I didn't have spares.
- The anti-peeping PIN code feature actually works, letting me punch in random numbers around my real code without issues.
Frequently Asked Questions
Does this lock have Wi-Fi for remote control?
No, it uses Bluetooth for app control within 2 meters. For remote control via Wi-Fi, you need to purchase a separate G2 Gateway.
How long do the batteries last?
The lock runs for approximately 12 months on 4 AA batteries. It includes a low-battery indicator and a USB Type-C port for emergency power.
What unlock methods are available?
You can unlock it using fingerprint recognition (under 0.3 seconds), PIN codes, physical keys, the app (via Bluetooth), eKeys, fobs, or voice commands with Alexa/Google Voice Assistant (with the G2 Gateway).
Is it difficult to install?
Installation is designed to be easy, taking minutes with just a screwdriver and no wiring required. It also has an adhesive-backed interior cover for hands-free setup.
Is the lock weather resistant?
Yes, it has an IP54 weather resistance rating and operates reliably in temperatures from -22โ to 158โ (-30โ to 70โ).
Buying Guide
When you're looking at smart locks, don't just focus on how many ways it can unlock. Think about how you actually want to use it day-to-day. Do you need to let someone in when you're not home? That's where Wi-Fi or a gateway comes in. If you just want to ditch keys and use your finger or a code, a Bluetooth-only lock might be fine. Also, consider the battery life and what happens if it dies.
BHMA Grade 3 Standards
This isn't just marketing fluff; it means the lock's key components have passed rigorous tests for performance and durability. It's like a crash test rating for your door lock, indicating how well it can stand up to wear and tear and attempted forced entry.
Fingerprint Recognition Speed (<0.3s)
This tells you how quickly the lock will identify your fingerprint and unlock. A speed under 0.3 seconds means it's almost instantaneous, so you won't be standing there waiting for your door to open, especially when your hands are full.
Bluetooth vs. Wi-Fi (with Gateway)
Bluetooth means you can control the lock with your phone only when you're very close to it (like within 2 meters). Wi-Fi, usually enabled by a separate gateway, lets you control and monitor your lock from anywhere with internet access, like checking if it's locked while you're at work.
Alternatives
If you need remote Wi-Fi control without an extra purchase, look for models with integrated Wi-Fi. If you need more advanced smart home protocols like Z-Wave or Zigbee, check for locks that explicitly support those standards.
