Our Review

Looking at it as an overall product, the ARRAY smart lock earned an 8.3/10 weighted average score. This a great lock for people who don’t already have smart home systems, or who use the Amazon Echo as a smart home hub.

In addition, this lock is sturdy enough to handle a household with children.

For those who use other smart home systems, however, or want a smart lock that integrates with smart devices, there are other (less expensive) smart locks on the market that would be a better fit, since this lock doesn’t currently integrate with anything but Alexa.

For more information about this lock, you can go to the manufacturer’s website.

Ease of Use

Everyday usage and multiple users

This smart lock works beautifully for some users, but not very well for others.  Access code entry is easy, and there are typically no issues with this feature of the lock.

One big plus for this lock is the keypad. The keys are made of metal instead of rubber—a huge upgrade from most other smart locks on the market.

The numeric keys are kept in pristine condition by remaining hidden under the solar panel until they’re ready for use, although this was a turn-off for some, who noted that it was difficult to slide the solar panel up to access the keypad.

However, remote access was iffy at best for some users, who reported not being able to check the status of the lock while away from home or remotely control the lock when traveling.

It was a mixed bag when it came to assigning e-keys or access to other users as well, with some reporting no issues whatsoever, and others being unable to give anyone else access to the lock.

Other users reported connectivity issues, stating that the lock wouldn’t remain connected to their Wi-Fi network, or the app would lose the ability to communicate with the lock.

Some of these issues may depend on whether the lock is connected to a 2.4 or 5.0 GHz home network, and since information is sent from the app to the cloud and back to the lock, if there are problems with the cloud’s server, there will be issues with the app or the lock’s ability to connect.

For those reasons, we gave this smart lock a 7.5/10 in the ease of use category.

Smart Home System Integration

Which systems is this smart lock compatible with?

You can use this smart lock with Amazon Alexa (if you have an Amazon Echo).  Plans have been announced to add integration with Google assistant and Apple HomeKit, but those features were not yet in place at the time of this article.

If you use Alexa, you can both lock and unlock your door with voice commands and also check whether the door is currently locked or unlocked.

Because this smart lock is compatible with Alexa, but not other smart devices or smart home system such as Google Home or Apple HomeKit, it gets a 7.5/10 rating in this category.

Ease of Installation

Physical installation of this smart lock is pretty simple:  you just need a screwdriver. You do, of course, need to remove your old lock prior to installing this one.

There are installation videos, PDF installation instructions, and step-by-step installation guides available on the manufacturer’s website.  This is, by far, the most installation help we’ve seen on any smart lock manufacturer’s website.

This lock will fit any standard-sized door (1 ⅜” to 1 ¾”).

Once the old lock is removed, following the installation instructions in the app or online is fairly simple.  However, if you are using the PDF version, you’ll need to switch over to the video after installing the interior housing, since the PDF instructions cut off there.

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

1)    Install the new deadbolt that comes with this lock.

2)    Install the new strike plate.

3)    Attach the gasket to the lock’s exterior housing.

4)    Next, install the exterior housing to the outside of the door.

5)    Install the lock’s mounting plate.

6)    Once those are in place, connect the cable inside the lock.

7)    Attach the interior housing to the inside of the door.

8)    Open the keypad and press the ARRAY button while adding the battery pack.

9)    The lock will beep, and the keys will flash.

10)  After selecting the correct number on the keypad (as indicated in the installation video), the lock will complete the door handing process.

11)  Once that process is complete, attach the battery cover while applying pressure to the battery.

Because this lock comes pre-installed with built-in Wi-Fi, it’s ready to connect to your home’s network.  You do not need a smart home hub or any other accessories in order to link up to your home network.

The only caveat, which is the same for all smart locks, is to be sure that your door is aligned properly so the hole for the deadbolt lines up with the deadbolt.  Otherwise, you may have issues with the deadbolt jamming or not locking.

The last part of the installation/setup process requires a little more attention to detail than some smart locks, and needing to apply pressure to the battery while simultaneously attaching the battery pack takes some practice.

For those reasons, we gave this lock an 8/10 on installation.

Robustness of the App

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

With the ARRAY by Hampton app, you can lock and unlock the door, check the battery life, assign an unlimited number of access codes and e-keys, see who has accessed the lock and when, and check the lock’s status.

The app is free to download and works with both iPhones and Android smartphones.

You can also enable geofencing so the lock will sense when you’re near and ask (via an alert) if you’d like to unlock the door.

The access codes or e-keys can be limited to one-time use or a recurring schedule, or can be set for always being active, depending on who is using them.

E-keys allow users to see the lock’s status and lock or unlock the door via their smartphones.

This app is also compatible with Android Wear 2.0 (or later) and Apple smart watches.

However, a fairly high number of users noted that the app could be finicky and wasn’t always able to connect to the lock or their home networks.  Again, this could be a symptom of having to send data back and forth over the cloud instead of communicating with the lock directly.

For those reasons, the ARRAY smart lock’s app gets an 8/10 in this category.

Getting In

How this smart lock opens the door

This smart lock gives you multiple options here.  There’s a place on the lock to use a physical key, but it also uses geofencing technology to sense when you’re near the lock.

It will then ask you (via an alert on your smartphone or smart watch) if you’d like to unlock the door.

In addition, you can also unlock the door by entering an access code on the lock’s hidden keypad (the panel slides up when you want to use it).

You can also, of course, lock or unlock the door via the app from your phone or smart watch, and even tell Alexa to lock or unlock the door for you using voice commands.

Because this smart lock offers several options for getting in, it gets an 8.5/10 in this category.


Is it worth the $298 price tag?

This lock retails for a standard cost of $298; however, we found it online for as low as $225.

This is one of the more expensive smart locks on the market.  For this price, we were hoping for a few more features, or at least integration with a few more smart home devices/systems.

While it has been reported that eventually integration will be offered for Google assistant and Apple HomeKit, there is no time frame for when this will happen.

Having the solar panel slide over the keys and protect them from the elements is a nice touch, but many users stated that having to manually move the cover to enter the code each time is more of a nuisance than a helpful feature.

It was also noted that the solar panel didn’t seem to affect battery life very much, with some users wondering if the solar panel was actually charging the battery at all.

Having the Alexa integration is nice (though it requires having an Echo), but we were hoping for a few more features or integrations at this price point.

For those reasons, the ARRAY smart lock earns a 7/10 from us in the value category.

Remote Connection Type

Wi-Fi, Bluetooth, or Both?

This smart lock has a built-in Wi-Fi connection, meaning that you don’t need to purchase an additional hub to connect to smart devices/systems or your home’s Wi-Fi network.

Because this lock relies on the cloud to make connections/store data, your ability to remotely access the lock is dependent on the cloud’s stability, which is something to keep in mind when choosing whether or not to purchase this lock.

The ARRAY smart lock earned itself an 8/10 here for having a built-in Wi-Fi connection.

Power Options

The ARRAY smart lock uses one rechargeable lithium polymer battery.  It will take between three and six hours to recharge the battery, depending on whether you use the charging cradle or a micro-USB cable.

Although the manufacturer states the battery should last about 30 days prior to recharging, users reported that the average battery life is actually only about two weeks before needing a recharge.

Keep in mind, you will be unable to remotely control the lock while the battery is charging, which is the one downside to using rechargeable batteries in a smart lock.

You will, however, still be able to lock or unlock the door with a physical key or with the thumb turn when the battery is being charged.

Since this lock comes with a spare rechargeable battery, however, hopefully you’ll always have a fully charged backup on hand.

In addition, it’s the only smart lock we’ve reviewed that has a solar panel to charge itself if your door receives direct sunlight during the day.

The app also alerts you when the batteries are low, and while nice, many other smart locks also include a low-battery indicator on the lock itself.

We balanced the inconvenience of losing remote control of the lock while charging the battery against the built-in solar panel, spare battery, and in-app low battery alert, and gave this smart lock a 9/10 in this category.

Lock Type

Lock attachment or full lock?

This is a complete locking system and comes with a full deadbolt assembly in addition to the other components.  This is considered to be the safest type of smart lock when compared to those that simply attach to an existing lock.

It has been rated at ANSI 2, meaning it’s a good, strong lock, but not the best lock (ANSI 1).  Many users also commented on the sturdiness of the lock itself.

Because of the strong ANSI 2 rating, multiple positive reviews about its hardiness, and the fact that the deadbolt comes with the lock, we gave the ARRAY smart lock 9/10 here.

Keys or Completely Keyless Entry?

This lock gives you the best of both worlds, by allowing for three different keyless entry methods when you want it, while still giving you the option of using a key, for those who aren’t ready to toss their house keys just yet.

We gave this lock an 8.5/10 for having a physical key, several different keyless entry methods, a solar panel, and the in-app low-battery warning.



This lock comes with a lifetime warranty on the mechanical parts and finish, and a one-year limited warranty on the electronic components.

While not bad, other smart locks on the market come with two- or three-year warranties on the electronic components.

Because of the decent warranty, the ARRAY smart lock earns itself an 8/10.

Additional Features

This lock has a solar panel that hides a numeric keypad.  When it’s time to use the keypad, you can slide the charging panel up and the keys underneath are revealed.

The keys on the numeric keypad are backlit for easy use at night, and because they’re kept safe from the elements by being underneath the solar panel, you won’t have to worry about dust or water damage.
