Top 5 Cheap Smart Door Locks to Buy in 2020

August Smart Lock (3rd Gen.)

My pick for the best smart lock is the August 3rd Generation. I ranked it number one because it provides all the features you'd expect.

Like temporary guest codes, easy installation and it's compatible with Alexa, Google Assistant and Apple HomeKit. All that for some of the cheapest pricing I've managed to find online.

One of the drawbacks of a smart lock for doors is that you never know if the doorway is open or closed after the lock has been engaged. Even with alert notifications, all you see is that a change in the lock state has been recorded.

DoorSense™ fixes all of that by telling you if the door is opened or closed after the lock has been set.

The extra sense of security of this August Smart Lock prevents anyone from trying to trick the system by keeping your door ajar after the lock has been engaged.

Key Features:

  • Access Codes for Guests
  • Auto-Lock and Unlock Feature
  • LED Indicator of the Battery Life
  • Easy to Use and Install
  • Works with Google Assistant, Apple Homekit, Samsung Smartthings and Alexa (With Add-On Hub)

Another cool thing about this smart device is that it has a blue LED light ring. This gives you a visual indication that the smart lock has sensed your arrival and blinks to let you know that your smartphone signal has been received.

All-in-all it’s a great wireless lock you can find and buy.

Schlage CAM 619 WiFi Door Lock

If you’re looking for a low price smart lock you can buy that has an illuminated keypad lock. This can be a great option as well.

It gives you the ability to store up to 30 access codes so that you can provide access to all family members, and they can have their user codes.

It also has a built-in alarm where you can find three smart alert settings. You’ll know instantly when there’s any activity, if someone is tampering with the lock or if a forced entry has occurred.

Something to keep in mind about this smart lock is that you can’t pair it to the Bluetooth.

Therefore, it can’t auto-unlock on your arrival. You can, however, lock and unlock it through your smartphone, but you’ll need to install a Wi-Fi hub to take advantage of that feature.

A final word about this deadbolt lock is that it comes in 6 finishes: Aged Bronze, Bright Chrome, Camelot, Matte Black, Satin Chrome, and Satin Nickel.

Kwikset 910 Smart Door Lock

My final recommendation for the cheap smart lock is another version with a keypad.

The keypad on this Kwikset lock uses push buttons and is not as fancy as the Schlage touch panel.

It doesn’t include the built-in alarm feature to alert you to the type of activity at your front step.

Because of those reasons, it’s a little bit cheaper than the Schlage lock.

Finally, there are several finishes available to choose from, including Satin Nickel, Polished Brass, and Venetian Bronze as well.

Key Features:

  • Program up to 30 Custom User Access Codes
  • History and Log Notifications
  • Z-Wave Plus Smart Home Automation System
  • Keyless Entry: Keyway and Touchpad

Features of the Best Smart Locks

There are a few things you’ll want to take note before you find and buy a smart door lock. The truth is that not all products work the same way.

By paying attention to what options are available on these smart home devices (and which ones you care about). You’ll be able to find the best Wi-Fi lock for your needs while saving the most amount of money. (Check this out: other smart and good ideas for your home.)

Bluetooth

Bluetooth for smart home

If you want to walk up to your front door and have it automatically unlocked for you (and re-lock when you leave), then you have to find a smart device that can connect to a Bluetooth. If you cannot connect it to the Bluetooth, the device has no way of knowing what your proximity is to the lock and how it should behave.

Unfortunately, Bluetooth is not a standard feature on all smart devices. So, if you want a hands free experience coming in and out of your house, you need to look for this feature as well.

Three out of the five best products I reviewed above can connect to the Bluetooth.

Wi-Fi Hub

Here’s something you’ll quickly realize when searching for the best smart lock – you still can’t operate it remotely out of the box.

That may seem counter-intuitive since these products are supposed to be able to let you operate them no matter where you’re located. However you’ll need buy a Wi-Fi hub that pairs your smart lock to your wireless router so that you can operate it over a Wi-Fi Network.

Without a hub, you’ll need to be next to your lock to make any adjustments using an app.

The most popular Wi-Fi hubs that connect with smart door locks and other smart home hub devices are SmartThings and Wink. You can also buy products have Pin Genie Technology as well. An anti-theft technology for expensive products.

If you want to operate your lock from anywhere in the world, you’ll need to make sure to connect to one of these hubs and pair it with your device. [1]

Virtual Keys

A fascinating feature that can be found on some smart door locks is the ability to send people virtual keys as well. What this means is that you can give visitors access to unlock your door using their smartphone. No access codes or physical keys are required.

This is convenient if you want to allow house guests, cleaners, babysitters, service people, and more inside your smart home when you’re not still there.

Virtual keys can expire after a single use or last for more extended periods. The choice is up to you.

History Log and Notifications

Doorbell chime

Another nice feature in a smart lock is a recorded history of all the locking and unlocking of the door lock. This is especially good to know if you’re going to be handing out a lot of virtual keys or want to keep tabs on other people who share access to your smart home.

Some units send out notifications to your smartphone, alerting you of any activity. Still keep in mind that this handy feature is not available on every affordable lock.

Plus a Wi-Fi hub must be installed so the lock can communicate with your smartphone over an Internet connection.

Fortunately, the smart locks I recommended above include this accessible functionality.

Keypad

electronic keypad

A final thing you may want to consider if you buy this product is a keyless entry lock. That means you have to check if it has a keypad or not. While the whole purpose of having a smart lock is so you can control it from your smartphone, a keypad does come in handy sometimes.

For example, if a visitor doesn’t have a smartphone and needs access to your smart home, they can type their assigned user codes to unlock the door. They don’t need to get a physical key.

Another common scenario is if you or someone in your house forgets (or loses) their phone and can’t get back inside. A keypad is a simple solution.
