Best smart locks iMore 2021

Our houses, apartments, and offices are filled with connected home accessories, so we aren't afraid to install a smart lock (or four) on our doors. Put simply, we've very nearly tried them all, and that's why we decided that the August Wi-Fi Smart Lock is our top pick. It has simple installation, compatibility with multiple smart home systems, excellent design, and an easy-to-use app. It gives you everything you need to add smart, wireless access to your home for you, your family, and your chosen guests.

Best overall: August Wi-Fi Smart Lock

August Smart Lock ProSource: August

August's newest model is unique because it connects directly to your Wi-Fi, meaning you don't need the Connect Bridge to control it as you do with other August smart locks. Just take it out f the box, set it up, and you're good to go. It's the best August smart lock you can buy, and it's the best smart lock you can buy, period.

If you get tired of fumbling with keys, worrying about whether you locked the door when you left the house, buying new spare keys for your children, or precariously placing a spare key in one of those entirely unsafe fake rocks, this smart lock is for you. August lets you create virtual keys for friends and family staying at your place. It also keeps tabs on the comings and goings of your household using a built-in 24/7 activity log.

Its appearance is immediately striking and will give any door a futuristic look, with your choice of dark gray or silver finishes. You can use your smartphone to unlock or lock your door remotely. Or you can set up a proximity lock: Your entry will unlock when you approach with your phone and lock when you move away.

The August smart lock requires no wiring and installs using an existing deadbolt. It also works with HomeKit, Alexa, and Google Assistant, so you can control it with Siri and the Home app for iOS and just about every other smart device you own.

Pros:

  • Simple installation
  • Works with Alexa, Google Assistant, and HomeKit
  • Long battery life
  • Automatically locks and unlocks your door for you
  • Virtual keys

Cons:

  • Only works with single-cylinder deadbolts
  • No outdoor keypad

Best for Nest: Nest x Yale Lock

Nest x Yale LockSource: Google Store

The Nest × Yale lock supports notifications, letting you know when someone operates the lock. You can set up passcodes that expire after some time if you plan on having guests or need a maintenance person to gain temporary access to your home. What's more, the lock uses geofencing tools to lock when you're not around automatically — no more forgotten doors.

The lock replaces your deadbolt, offering a tamper-proof and secure solution to keep your door locked up tight. If the lock ever senses tampering, it will send you a notification. There's also a handy feature I'm particularly excited about: If your lock ever loses power, you can use a 9-volt battery to charge and unlock the door quickly.

The Nest × Yale lock is perfect for anyone with Nest products in their home, and while it may not work with HomeKit, it will work with other accessories like Google Home. It's built to integrate with the system and requires the Nest Connect or Nest Guard to interface with the rest of your Nest system and connect with the Nest app.

Pros:

  • Reliable
  • Long battery life
  • Tamper-proof
  • Simple installation

Cons:

  • Pricey
  • No Apple HomeKit support

The Samsung SHS-3321 is a reliable, sleek-looking, and easy-to-use smart lock that's battery operated with an emergency power connect if the batteries die.

The lock is designed without a keyhole, making it accessible via touchpad, while a magnetic sensor automatically locks the door behind you when you leave. If you're away for a long time, the lock even has an away mode that can be activated to monitor and track movement, kind of like a home alarm system.

The Samsung SHS-3321 is both affordable and sharp-looking, making it ideal for putting on several different doors around your home — not just your front door. Silent mode means that you can put this lock on the door of your baby's room and not worry about sounds waking them up in the middle of the night.

Pros:

  • Affordable

Attach it to your current deadbolt so you can continue using your current keys. Set it to lock automatically when you leave and unlock automatically when you come near.

The August Smart Lock Pro is incredibly easy to install with ten minutes and a screwdriver. Purchasing it opens you up to August's entire line of smart home products — including a smart keypad and doorbell camera. It's reliable, stylish, and perfect for anyone looking to add smart, wireless access to their home.
