Our Review

This lock is an excellent choice for Airbnb users and landlords—batteries last longer than most others in the industry, the outer side of the lock is the existing deadbolt, so you’re not advertising that you have a smart lock installed, and users have reported relatively few issues.

All good things to have for a rental property’s smart lock!

After careful consideration, the Danalock v3 smart lock earned an 8.3/10 average weighted score.

Ease of Use

Everyday usage and multiple users

This smart lock is actually fairly simple to use—there are no complicating bells and whistles on the lock itself, and the app is pretty straightforward, telling you exactly who locked or unlocked the door and when.

You can use the app to remotely lock/unlock when within Bluetooth range, or if using the optional wi-fi adapter, from anywhere.

Because this is a lock attachment that fits over your existing lock, you always have the option of using a physical key, so you’ll never have to worry about getting locked out.

For those reasons, we gave the Danalock v3 smart lock an 8/10 in the ease of use category.

Smart Home System Integration

Which systems is this smart lock compatible with?

This smart lock works with Apple HomeKit (if the HomeKit version is purchased), SmartThings, and Alarm.com.

However, you will need to purchase the optional wi-fi bridge to connect to any smart device if you are using the Bluetooth-only version of this lock and not the Z-wave plus or Zigbee enabled version of the lock.

It also works with Amazon Alexa if using the Zigbee or Z-wave plus versions of the lock.

Because this smart lock is compatible with several systems, but only with a wi-fi adapter or the more expensive Z-wave plus/Zigbee versions, it gets an 8/10 here.

Ease of Installation

This smart lock attaches to your existing deadbolt. You will need to remove the inside portion of the deadbolt, but keep the exterior portion attached to the outside of your door.

The online installation instructions are easy to follow and come with large, easy to understand illustrations.

There are only a few steps in the installation process, which we list below to help you make your buying decision.

  1. Remove your old thumb turn.
  2. Choose the correct backplate to match your lock type and attach it on the inside of your door.
  3. Select the appropriate tailpiece adapter to fit your existing lock and insert it into Danalock’s exterior housing.
  4. Align and attach the exterior housing to the door.
  5. Turn the lock until it clicks into position.

That’s it!

The lock is made from anodized aluminum, a nice step up from the Sesame lock’s plastic exterior housing.

Because of the quick installation process (and being a one-person job), this lock gets a 9/10 on installation.

Robustness of the App

What the app can do and how easy it is to use

The Danalock v3 smart lock app allows for true remote access if you purchase the optional wi-fi adapter. The app is free and works with both Android and iPhones.

With the app, you can add and remove an unlimited number of users and assign temporary access, see the lock’s usage history, lock or unlock the door remotely, and see the lock’s status. You also have the ability to activate the auto-lock feature through the app.

Because this app has all the standard features of other smart lock apps, plus allows unlimited users, the Danalock v3 smart lock gets a 9/10 in this category.

Getting In

How this smart lock opens the door

If you purchase the lock by itself, you can unlock the door remotely as long as you’re in Bluetooth range. If you purchase the additional wi-fi adapter, you can lock or unlock the door remotely from anywhere using the Danalock app.

Since this smart lock attaches to your existing lock, you can also use a physical key to lock or unlock the door.

There is also an optional keypad for users to enter access codes to unlock the door.

The Danalock v3 smart lock offers several options for getting in, but the keypad and wi-fi adapter must be purchased separately, so it earns an 8/10 in this category.


$173-$230, $97 keypad, $79 wi-fi bridge

This lock retails for between $173 and $230, depending on whether it’s the Bluetooth-only version, or Z-wave/Zigbee enabled.

The optional wi-fi adapter costs an additional $79 for true remote access through the app, and to connect to smart devices for the Bluetooth-only version. However, the $230 Z-wave plus or Zigbee versions do not need the bridge to connect with smart home devices (but will need it for remote access through the Danalock app).

If adding the optional keypad, that will be between $270 and $327 for both the lock and keypad.

Note that the keypad doesn’t work with Apple HomeKit yet, but this functionality will be added in the near future.

While this would be a great value if it were a full lock assembly, it’s a bit pricey for a lock attachment, especially considering that some smart locks offer built-in wi-fi for roughly the same cost and have additional included features, such as touchpads, that don’t require an extra purchase.

It does offer integration with Alexa, Apple HomeKit, SmartThings, and Alarm.com, which is more than several other smart locks offer.

Balanced against the good smart home device integration but limited options when compared to other smart locks, Danalock v3 is average in overall value.

Remote Connection Type

Wi-Fi, Bluetooth, or Both?

You have four available versions of this lock—one that uses Bluetooth only, one that adds Z-wave plus technology, and one that adds ZigBee technology. (The fourth version, Apple HomeKit, uses Bluetooth technology.)

Options are great, but this separation into four different locks has created some confusion on the part of buyers.

Because you can select from one of three connection versions, we gave the Danalock v3 smart lock a 9/10 here.

Power Options

The Danalock v3 smart lock uses four CR123A batteries. According to the manufacturer, these should last between 12 and 18 months before needing to be replaced.

There’s a low battery warning in the app, but it’s been reported that it’s not always accurate, and may indicate batteries are lower than they actually are.

We balanced the cost of replacing the batteries against the frequency of replacement and the low-battery warning feature and gave this smart lock a 9/10 in this category.

Lock Type

Lock attachment or full lock?

This smart lock attaches to your existing single deadbolt, which is considered less secure than smart locks with a full locking assembly. However, it is metal and not plastic.

But, the lock attaches to the door by clicking into a plastic assembly that is drilled into the door. Some users complained that if the lock gets bumped into, it can come loose.

Since this is a lock attachment and not a full locking system, and because some users have reported the lock moves out of place when bumped into, we gave the Danalock v3 smart lock a 7/10 here.

Keys or Completely Keyless Entry?

Since this lock fits over your existing lock, you still have the option of using your key—it doesn’t replace your existing lock’s exterior.

Otherwise, you can lock and unlock the door remotely via the app, via access code using the optional keypad, or within Bluetooth range with auto-unlock.

If the Z-wave plus or Zigbee options are purchased, you also have the option of using voice commands through Alexa.

We gave this lock an 8/10 for offering both keyless and physical key entry methods.


1-year limited

This lock has a one-year limited warranty that covers defective materials or manufacturing defects.

Other smart locks on the market, however, come with two- or three-year limited warranties on the electronic components and limited lifetime warranties on the finish and mechanical parts.

Because of the lackluster warranty, the Danalock v3 smart lock earns itself a 6.5/10 here.

Additional Features

Danalock v3 has an optional keypad (“Danapad”) for access-code entry in addition to the remote entry.
