Now you no longer have to worry about those duplicate keys you gave to your sitter or house cleaner. You can say goodbye to leaving a key under the mat for guests. Smart locks are growing in popularity, thanks to the convenience and added security they give you.

But how do they work? And what’s the best one for your home or business?

Article Overview

What Is A Smart Lock?

A smart lock consists of three components: a deadbolt lock, a motor and a transceiver. The motor operates the deadbolt (instead of a standard key), and the transceiver, which connects to a smartphone app or home automation system, sends and receives a remote signal.

Our reviews focus on Bluetooth-enabled smart locks, meaning you can lock and unlock your front deadbolt using your smartphone. All of the locks in our reviews also have features where you can connect your lock to become a remote WiFi deadbolt — i.e., you can lock or unlock your door no matter where you are. The WiFi mechanism differs with each smart lock.

What’s The Best Smart Lock?

We based our rankings on several factors and features, giving the most weight to security features.

Winner: Schlage Sense Smart Deadbolt Review

Schlage Sense Smart Deadbolt

View on Amazon

Unlike other smart locks, Schlage detects when someone unlocks the door with a key or via the keypad, rather than merely tracking when someone uses the app to unlock the door.

This lock also has a built-in siren that activates when someone tries to force your door open, which gives you peace of mind during the nighttime. Although Schlage doesn’t have an auto-unlock feature, we don’t see that as a negative (other than inconvenience); rather, it’s an added security measure in our book.

Runner-Up: Kwikset Kevo 2nd Gen Review

Kwikset Kevo 2nd GenView on Amazon

If you have an Android smartphone, Kwikset Kevo is likely your best smart lock choice. The Kwikset 2nd Gen Bluetooth deadbolt’s best feature is its unique touch mechanism, where you don’t have to open the app to lock or unlock your door — you simply touch your smartphone to the lock.

You can easily customize your e-key settings for family, friends and others who need access to your home, but additional e-keys are an added charge. Unlike Schlage, you can add on a key fob. Kwikset’s deadbolt lock is Grade 2 level security — a high level, but not as high as our number one pick.



  • ANSI/BHMA Grade 2 certified deadbolt
  • Compatible with iOS and select Android devices
  • Easy to install and configure with standard keys (2 included)
  • Key fob (additional charge)
  • 24-hour guest e-key access and customized e-key access for pet sitters, housekeepers, etc.
  • Compatible with Nest, Honeywell, Ring and Skybell smart doorbells
  • 1-year electronic warranty
  • No built-in siren
  • Only monitors when someone unlocks your door using the app (no key use or tamper monitoring)
  • No keypad available
  • WiFi adapter for remote access is additional $99
  • Additional e-keys are $1.99

Pricing & Tech Specs

  • 4 AA batteries included
  • Dimensions: 5.75″ x 2.75″ x 2″

3rd Place: August Smart Lock Pro Review

August Smart LockView on Amazon

Easy DIY installation is one of August’s best features. Unlike our top two winners, the August Smart Lock Pro doesn’t replace your existing deadbolt, just the thumb turn inside the door. What’s the safety factor here? This keyless door lock relies on the safety quality of your existing deadbolt, so make sure you have a premiere deadbolt already in place.

The app makes granting access a breeze with fully customizable settings, but it doesn’t track when someone uses a key to unlock your door or if someone tries to tamper with your lock. Still, the August Smart Lock has a robust set of features, and it syncs with more smart home platforms (Z-Wave, Apple HomeKit, etc.) than some of the companies in our other smart lock reviews.



  • Compatible with iOS and Android devices as well as Alexa, Siri and Google Home
  • Easy DIY retrofit installation (you only replace the interior of your deadbolt)
  • Easy-to-use app tells you who enters and when
  • Send unlimited free e-keys to family, sitters, guests and control their access
  • Keypad add-on (additional fee)
  • Compatible with August doorbell cam, Z-Wave, Apple Homekit, Apple watch, Nest Secure, Honeywell and XFINITY Home app
  • 1-year electronics warranty
  • Not compatible with some deadbolt types
  • No built-in siren
  • Doesn’t monitor when someone unlocks your door with a key or tampers with your lock or door
  • No key fob available
  • August Connect WiFi Bridge adapter for remote access is an added $73.22 (but Amazon has a great bundle price)

Pricing & Tech Specs

  • Smart Lock Pro: $299.99
  • Smart Lock Pro + WiFi Connect Bridge: $229.99
  • 4 AA batteries included
  • Dimensions: 3.3″ x 3.3″ x 2.2”

Other Smart Locks

Below are some other smart locks for you to consider. Although they didn’t make our top 3 picks, one may be the right fit for your particular needs.

Amazon Key | Danalock | SimpliSafe Smart Lock

Amazon Key Home Kit Review

Amazon KeyView on Amazon

Amazon offers an in-home kit for Prime members that includes an Amazon camera and compatible lock that allows Amazon packages to be delivered securely inside your home while you are away. It is only available to Prime members in select cities.

Once synced with your home WiFi and Amazon account, you’ll have the option to select “free home delivery” upon checkout which gives carriers the ability to remotely access your home and place your orders safely inside your home to prevent package theft.

The day of delivery you’ll get notified before the package is on the way. When the delivery person arrives, you’ll get an alert and can either watch live via Amazon camera or see a recorded clip. In addition, Amazon Key works with the Amazon professional services affiliate program so you can let cleaning crews, dog walkers or other handy people in with the ability to watch their entry and exit remotely.

Danalock V3 Bluetooth Smart Lock Review

View on Amazon

Danalock recently came out with their 3rd generation Bluetooth smart lock. The previous generations had issues with unreliable software, and although v3 is an improvement, not all bugs have been resolved.

In the end, this smart lock isn’t as popular as others listed in this review, so we’d probably suggest you consider one of those over Danalock. But if you find one of these at a great discount, it may be worth trying out.



  • Compatible with iOS and Android
  • Keypad add-on
  • Remote WiFi access available via home automation sync or app on an in-house smartphone/tablet
  • Compatible with Z-Wave, Nest, Apple Watch
  • 1-year electronics warranty
  • May not work with some types of deadbolts (but it’s more flexible than August)
  • Retrofit installation (like August, you use the existing deadbolt) not as easy as our other reviewed smart locks
  • No built-in alarm
  • Doesn’t log when someone uses a key or tries to force the lock (unless synced with home automation platform)

Pricing & Tech Specs

  • $316.79
  • 4 CR123A batteries
  • Dimensions: 2.5″ x 2.5″ x 2.83″

SimpliSafe Smart Lock Review

SimpliSafe Smart Lock

Visit Website

SimpliSafe’s Smart Lock will keep track of anyone who locks or unlocks your door, so you’ll know when the kids get home from school or when the cleaner finishes up for the day (monitoring plan required).

SimpliSafe Smart Lock notifies you if the wrong PIN is entered 5 times. After 15 attempts, it will remain locked for 30 minutes, and if you have a monitoring plan, SimpliSafe will call you. You can lock and unlock it using the PIN pad, key fob or your smartphone.

You can also create unique access codes for the dog walker, family members, contractors, etc.



  • Compatible with iOS and Android
  • Much lower price than our other reviews
  • No drilling needed, just a screwdriver
  • Security system add-ons
  • 60-day money back guarantee
  • Deadbolt won’t extend until the door is shut, so it won’t damage your door frame mid close
  • Requires a single-cylinder deadbolt to work
  • No built-in siren
  • Requires a monthly monitoring fee to monitor the lock through an app


Monitoring Options

Important to know…

You can purchase a SimpliSafe Smart Lock without adding on a monitoring plan; however, the system is almost useless without monitoring. You won’t be able to monitor it yourself or be notified if the lock is unlocked unless you pay a monthly monitoring fee.

Do Smart Locks Really Make You Safer? (Video)

Smart home products of all kinds are the hype of the day. But do they really increase your security over a traditional deadbolt lock? A Wall Street Journal investigation finds out.

Smart locks are part of a growing trend of home security and automation devices. They have come a long way over the last few years. But if you really want to protect your household, you should consider going beyond just a smart lock.

These days, you have so many easy DIY home security options that come with ready-made kits and detailed instructions. Most are easy to install yourself, which saves you hundreds of dollars that you’d fork out for a professional electrician/installer.
