Finding cheap smart locks for your home can seem like a daunting task, but there are actually plenty of reasonably priced devices if you know where to look.
All of the smart locks below balance safety, convenience, and bang for the buck, plus they’ll easily connect to smart home ecosystems from Amazon Alexa to Google Assistant. However, it is worth keeping in mind that many of these locks save you money by leaving out some features that you may find a necessity. In most instances, the feature left out is Wi-Fi for controlling the lock when you aren’t at home or connecting to your favorite smart home platforms like Google Assistant or Amazon’s Alexa. But, should you want that option, you can purchase the compatible Wi-Fi bridge separately.
Our top pick is the August Smart Lock (3rd Gen), but keep reading to see which budget-friendly smart lock is right for your home.
At a glance
1. August Smart Lock (3rd Gen)
Best overall
This model of August Smart Locks is one of the least expensive ways to add some smarts to your home lock. You get many of the same features as more expensive models from August, but since this version only connects via Bluetooth, that savings is passed onto you. Should you want remote access when away from home, you’ll need to either upgrade to a different model or purchase the August Wi-Fi Bridge separately.
2. Hornbill Smart Lock Front Door
Best design
Hornbill managed to fit a lot of great features into this smart lock that are usually only found on more expensive versions. But this reasonably priced lock offers a keypad, key slot, and an included key fob, and via the app. But like the August model above, it only works via Bluetooth unless you purchase the Hornbill Wi-Fi Gateway.
3. Kwikset Home Connect 620
Best keypad
Kwikset’s simplistic, modern-looking smart lock keeps things clean and easy with a keypad and traditional key slot to lock and unlock the device. While this lock can connect with smart home services like Google Assistant and Alexa, the Home Connect 620 can’t be opened via your phone unless you purchase the hub separately that adds Bluetooth and Wi-Fi. That is unless you already have a smart hub that supports Z-Wave.
4. SwitchBot Wi-Fi Smart Lock
Best value
When it comes to smart home devices, SwitchBot makes a lot of unique products that are also quite affordable. This smart lock falls into both categories, as the way this works is by physically turning your existing lock knob. So, you don’t even have to use tools to install this device. It has Bluetooth installed and can be unlocked using a variety of methods. For Wi-Fi, you’ll need to buy a bridge separately.
5. Schlage Camelot Connect smart lock
Best alarm
Like others on this list, you’ll need to purchase a Wi-Fi hub separately to access the features it enables, like controlling it when away from home. But with the Schlage Camelot Connect smart lock, you do get the built-in keypad to unlock it, and it also has an alarm that sounds when the device detects it is being tampered with.
6. Lockly Flex Touch Deadbolt
Best fingerprint reader
Lockly makes some pretty high-end smart locks with lots of features. While this model may look basic, it is a great smart lock with a very good fingerprint reader. You’ll have Bluetooth control to use your phone, and if the battery dies in the device, you can use a 9V battery to power it so you can open your door to change the lock’s batteries.
Best overall
August is one of the best-known smart lock companies in the industry. What makes this one so much less expensive than the other August smart locks is that it doesn’t come with internal Wi-Fi like the August Wi-Fi Smart Lock or even a Wi-Fi bridge. As long as you’re near enough for your phone’s Bluetooth to interact with the lock, you’ll be able to open and close this device using the August app. If you really want to, you can purchase the August Wi-Fi Bridge separately, which will allow you to interact with the lock from anywhere as long as you have access to the internet. The bridge also makes it compatible with smart home devices like Amazon Alexa and Google Assistant.
The lock is installed on the interior, and while bulky on the inside, you won’t be able to tell that a smart lock is even installed on your front door when looking at your house from the street. However, using the August app, you’ll be able to adjust your settings, give out keys to guests so they can access your home, or track any unlock activity associated with your door.
Another key feature is being able to set up auto-lock and unlocking. Basically, the lock can detect when your phone approaches the door and when it leaves and changes its lock positioning accordingly. This feature can be helpful if you’re coming home with a large load of groceries and don’t want to fumble for your keys or your phone.
Best design
This is the latest model from Hornbill. It sports a sleek pin pad design and installs in place of your current deadbolt. Family members can either type in their specific code to enter the house or can whip out their phones and use the Hornbill app in conjunction with Bluetooth to control the device. As with the August Smart Lock, this one doesn’t include built-in Wi-Fi. However, homeowners can purchase the Hornbill Wi-Fi bridge if they decide to control the smart lock from anywhere.
You’ll notice that two metal prongs sticking out from beneath the key slot. That’s there in case the batteries die while you’re out. If you hold a 9-volt battery to that spot, the device will have enough power for you to type in your code or use your phone to unlock the bolt. It’s a nice little safety feature.
It should only take you about 20 minutes to get this device installed on your door as far as installation goes. There are handy instructions to help you with the process. Once installed, you’ll be able to check the lock’s history and adjust the settings via the app.
Best keypad
The Kwikset Home Connect 620 is yet another well-priced smart lock. It sports a pin pad and has a relatively simple design, making it stand out much less than other smart locks. It does have the potential to work with Wi-Fi and Bluetooth, but as with the other products in this roundup, you’ll need to purchase a hub to make that work. When the hub is in place, you’ll be able to open the lock using your app, the pin pad, or your key. You also get a host of compatible ecosystems with the hub, including Google Assistant, Alexa, Samsung SmartThings, Ring, Wink, and Vera.
Choose from the over five diverse color options to best match your door, with small price increments for various shades and finishes. You can even upgrade to the Smart Lock Keypad + Handleset if you want your lock and door handle to perfectly match colors. Just note that there is no battery life indicator on this device, so you’ll need to pay attention to the battery on your own.
Best value
The SwitchBot Smart Lock is one of the only smart locks on this list to come with a wireless keypad. Considering how little this device costs, this is a great deal just on that feature alone. You can adjust the locks settings in the SwitchBot app. Aside from using your phone or the keypad to unlock the door, you can also use the NFC card to swipe and open it up. In our testing of this lock, we found that all of these methods worked great in controlling the lock.
If you don’t want to replace your current deadbolt, then you’ll be happy to know that this one gets put in place over your existing hardware. That means you’ll still be able to use your original keys and deadbolt to access the house. It is a little bulky and doesn’t have the prettiest design.
Best alarm
Anyone looking for a smart lock with an elegant design ought to consider the Schlage Camelot Connect. There are a few different colors to help you match your door. One of the things that makes this lock stand out is that it has a built-in alarm. So if someone is tampering with the lock, the alarm will hopefully scare them away. It also has an impressively long battery life, and a yellow light will turn on, letting you know when it needs new batteries.
The lock can remember up to 30 different access codes, giving you plenty of options for family members, close friends, or anyone who frequently needs access to your home, like nannies or maids. This feature makes it a helpful lock for a B&B, and you can easily use the app to monitor your lock’s activity. However, if you’re looking to control it via the internet, you need to invest in the Wink or SmartThings hub. Having one will also let you control it using Amazon Alexa or Google Assistant.
Best fingerprint reader
Nothing makes you feel cooler than doing something like a spy. This inexpensive smart lock features a fantastic fingerprint reader that can remember up to 99 fingerprints at a time. That’s more than enough slots for use in your home, for a special room at work, or for a neighborhood clubhouse. You can check the history of lock usage by looking at the Lockly app.
It comes in Satin Nickel, and though it would be nice to see other color options, it is a nice finish that should work with many home colors. As with many other smart locks in this price range, you will need to purchase the Lockly Bridge Wi-Fi adapter separately if you want to control the unit using the internet. But you will have control via your phone’s Bluetooth right out of the box. Another unique feature of this lock is the ability to use a 9V battery to power the lock so you can open it with a fingerprint should you not have the key and the device’s batteries have stopped working.
