One of many greatest issues I’ve run into with sensible dwelling door locks is they have a tendency to exchange the deadbolt or the latch. The Lockly Duo replaces each. I’ve blended emotions about this lock setup, however I feel these blended emotions come from coping with the unfamiliar slightly than failings on Lockly’s half. I do comprehend it was good to have each locks be sensible for a change and accessible through fingerprint, key, or code.

Lockly behaves in some uncommon methods. Each the door latch and the deadbolt are managed by a single door deal with. A push down unlocks each locks, and a pull up locks each locks. It positively takes some getting used to, and regardless of its overseas nature, I like that mechanism. Having a single deal with that releases each locks is solely simpler, even whether it is uncommon.

Set up and setup

Organising the lock required a bit of labor and a few advanced mechanisms. The lock is designed to cowl a deadbolt and a door deal with which can be spaced both four inches or 5 ½ inches aside. My door is 5 ½ inches, so it labored out. Or not less than it might have if my deadbolt maintain had been drilled to the right dimension.  Because it was, in an effort to match the quilt plate onto my door, I needed to grind a few ¼” of the door. That’s not Lockly’s fault. The quilt plate itself can be considerably bigger than the door latch on the skin, so it doesn’t have an ideal look. 

On the within, there’s an additional mechanism that mounts between the door latch and the door known as an interconnection plate. This plate connects the deadbolt and door latch to the only deal with. It’s not a nasty machine nevertheless it provides a layer of complexity to the lock that I didn’t count on. Plus, the interconnection plate doesn’t sit flush with the door deal with. It’s not terribly noticeable, however once I maintain a flashlight to the tip facet of the lock, I can see the sunshine on the opposite facet.

There’s no scarcity of sensible locks in the marketplace, however none of them management each the latch and the deadbolt.

The Lockly Duo additionally has an built-in wired door sensor for Lockly’s safety system.  I didn’t set up that since I have already got a Vivint safety system put in. However the truth that it’s wired to the door deal with and I couldn’t take away it was a bit annoying.


As soon as put in, you employ the Lockly app to arrange PINs and fingerprints for customers. The fingerprint sensor is situated on the facet of the door latch and a display above the door latch shows the buttons for the codes. More often than not, the display is off. A single faucet often turns it on, although often I wanted to faucet it a second time to get it to get up. Numbers displayed are randomized into 4 buttons with three digits per button. This ensures that no put on sample develops by repeatedly tapping the identical place for a similar codes. After getting into your code, there’s a form of “enter” button to press beneath the buttons, however there’s no indication that the button is an enter button. At a look, it seems like a fingerprint, so I initially mistook it as a manner of claiming: “Certain, you may enter a code, however don’t overlook about that fingerprint sensor.” The button wants a greater design, or it simply must say “enter.”

The fingerprint sensor works very properly, although I’m not satisfied the location is the perfect. When you might have a door deal with on the left facet of the door, your pure intuition is to achieve for the door together with your left hand. However while you do this, your fingers face away from the sensor. The fingerprint sensor is a bit too awkward to make use of a thumbprint, so you find yourself having to achieve throughout your physique to scan a finger in your proper hand, solely to then use your left hand to really open the door.

Software program

The app lets you lock and unlock the door as properly, and you might be supposed to have the ability to pair it with Google Assistant, nevertheless, I wasn’t in a position to get that to work. The app itself is pretty simplistic and straightforward to know. You employ it to set fingerprints and pin codes. Organising fingerprints works equally to establishing a fingerprint in your telephone. You press your finger on the sensor a number of instances till the app tells you you’re finished.

The app additionally lets you allow “welcome mode,” and that is one among my different most important misgivings with the lock. Welcome mode means your door stays unlocked on a schedule. That’s good, however throughout the summer time, when persons are out and in all day lengthy, it might be good if there was a button or knob that allowed you to unlock the door. Because it stands, the one technique to flip welcome mode on or off is within the app. That’s not very best.

Our take

Total, it is a neat machine, with some oddities (and a price ticket) which can be slightly arduous to get used to. It’s an ideal idea, to make sure. Utilizing one door deal with is loads simpler than individually locking and unlocking two locks. You continue to get the safety of a deadbolt, together with the comfort of a single door deal with. There are some quirks right here like the shortcoming to go away the door unlocked with out utilizing your telephone and the outsized mounting plates for the lock. The deal with additionally stands proud fairly a bit, which truly interfered with my display door. A variety of these are minor points that may definitely be addressed in a 2.zero product.

However at $450, you actually don’t need compromises from a door lock. That’s manner over twice the typical sensible door lock in the marketplace. That’s a excessive worth to pay for what quantities to slightly comfort. I usually go away my door latch unlocked as a result of, till the Lockly, solely my deadbolt was sensible. Having a door lock that works for each the latch and the deadbolt is nice, however I’m not satisfied it’s $450 nice.

Is there a greater different?

The fingerprint reader and code panel on the Lockly each work nice. There’s no scarcity of sensible locks in the marketplace — take a look at our listing of favourite sensible locks — however none of them management each the latch and the deadbolt. Is that the perfect factor on the planet? It’s definitely handy. There have been instances I’ve locked myself out of the home once I forgot to unlock the door latch. That’s by no means an issue with this lock.

For about the identical worth, there’s the last word sensible lock within the Lockly Imaginative and prescient. It’s the Swiss Military knife of sensible locks as a result of it incorporates all the fashionable conveniences, however serves double responsibility as a video doorbell as properly. If you happen to desire one thing a bit extra discreet, the Stage Contact seems like an strange deadbolt lock on any door and doesn’t have the distracting keypads and hulking latches sometimes related to sensible locks. And lastly, there’s the August Wi-Fi Good Lock, which is notable for its reasonable worth, straightforward set up, and unimaginable security measures.

How lengthy will it final?

I’ve no cause to suspect this door lock is not going to final. It’s constructed with sturdy supplies. The Locks are backed by a five-year mechanical and end guarantee and two-year electrical guarantee. The hole in between the interlock plate and the door deal with provides me pause, nevertheless it’s on the within, so it needs to be affected by rain. Normally, I’ve no sturdiness complaints.

Must you purchase it?

No. There are particular explanation why you wouldn’t need this lock from a practical perspective. In case your door doesn’t have an awning or different climate safety, you’ll discover the fingerprint sensor and code panel are very delicate to rain and can mainly cease working. If you happen to don’t just like the door deal with aesthetic and like doorknobs, it’s best to cross.

However the primary concern I’ve is within the pricing, which may be very steep. Put merely, you should buy a wise door latch and a wise deadbolt, and nonetheless have cash for a couple of packs of batteries earlier than you hit this worth threshold. Lockly must deliver the worth down earlier than it’s thought-about a strong purchase.
