What Makes a Lock a Smart Lock?

A smart lock uses technology like Bluetooth, HomeKit, or Z-Wave to offer remote control via your smartphone or voice controllers like Siri, Alexa, or Google Assistant.

Types of Smart Locks

There are two types of smart locks: the first is the ones that replace only the interior part of your traditional lock, and the second are ones that replace your whole traditional lock, both the interior and exterior parts. Some exterior parts come with a keypad, so that you can create and share access PIN codes with your family and friends.

If you’re looking for simple installation and want to keep the existing deadbolt, we’d recommend focusing on interior-only smart locks, like the August Smart Lock Gen 3 or Kevo Convert.

What are the Benefits of Smart Locks?

First of all, you can forget about physical keys. Some smart locks feature geofencing, so they’ll unlock the door when you approach it and automatically lock the door after you leave.

There are also locks with a keypad on the exterior side, so all you need to do is enter your PIN code to unlock the door. And when you leave, just press a lock button on the keypad to lock the door — It’s incredibly simple.

Also, with smart locks you can easily share access with your family, friends, and other guests. You can issue scheduled access to your home for a dog walker or handyman. Keyless access offers security at your fingertips — never again will you worry about lost or copied keys.

And if you’ve ever asked yourself, “Did I lock the door?” With a smart lock, all you need to do is open your smart lock app and check the lock’s status. Moreover, some smart locks, like the August Smart Lock Gen 3 and August Smart Lock Pro, feature DoorSense Technology to warn you if your door is ajar.

With remote control you’ll also get notifications whenever the lock is engaged, so you’ll never miss a visitor.

What Makes a Good Smart Lock?

So, let’s get this straight: there is no absolute best smart lock. Everything depends on what exactly you’re looking for and your home’s setup. However, here are a few important features to look for when choosing a smart lock:

  • Shared Access – some smart locks have limits to the number of access codes that you can share. So be sure to check the maximum number before buying if you want to have enough ‘eKeys’ for everyone;
  • Remote Control – make sure to check the options for out-of-Bluetooth-range control. You might need to buy a bridge/gateway separately to set it up;
  • Lock Grade – if you decide to go with a smart lock that replaces the exterior part of your standard lock, check the new lock’s grade. There are three lock grades: Grade 1, Grade 2, and Grade 3, with Grade 1 being the most secure of the three.

A good smart lock is a lock that actually works. Malfunctions are commonly caused by incorrect installation (when the deadbolt is not aligned with the hole), incorrect calibration, or low signal.

However, you can easily avoid these issues by ordering a Deadbolt Installation Service and getting extenders/repeaters for better signal transmission. And, if you’re planning on adding more smart products to your home, make sure to check out the Orbi Whole Home Mesh WiFi System for reliable and uninterrupted performance of your smart devices.

Our Favorite Smart Lock

August Smart Lock on a door

Our top pick is the August Smart Lock Pro – it supports HomeKit and Z-Wave Plus, so out-of-the-box it’ll play well with majority of the smart eco-systems. Also, the smart lock is easy to install because it replaces the interior part of your standard lock only. This way you get to keep your existing lock & keys and avoid unwanted attention.

Plus, the August Smart Lock Pro is one of the few locks that features DoorSense technology. The DoorSense feature lets you know if your door is open or closed, so you can enjoy piece of mind knowing that your door is both locked and closed.

The runner-up is the Schlage Connect – it’s a Grade 1 smart lock (the most secure residential deadbolt) with built-in alarm and a touchscreen keypad on its exterior side. The lock utilizes Z-Wave technology, so you can easily connect it to you Wink or SmartThings hub.
