If you're looking to boost your home security then getting your hands on the best smart lock will need to be on the list of priorities.
We're adding reviews to this guide all the time, but sourcing new smart locks and testing them is proving a little tricky for us at the moment. Still, we've included our top three picks for this month that we have managed to review and we've also included some other fab options which would be worth considering.
Note: there is more availability in the US for the smart locks featured - we're working on adding more options to the guide for our UK readers.

Owning one of the best smart locks is certainly a smart idea if you're prone to losing your keys, or you don't / can't want to open the door when the doorbell rings. They are also a good little boost to your home security system and best home security camera with many smart locks now capable of integrating through an app, plus Philips Hue, Google Assistant and Amazon Alexa.
We reviewed three smart locks in this guide to include a best overall, budget and premium option. The smart locks which gets our vote for #1 is the Google Nest x Yale smart lock. Why? It's easy to use, very well-designed, and is controlled through an awesome app. A downside (and perhaps a deal breaker) is that you'll need to already be using Nest, or be willing to. If that doesn't sound like the best smart lock for you then we'd happily recommend with either the Schlage Sense Smart Lock or August Smart Lock Pro which are compatible with other connectivity's, although the app let us (and them) down in review. Read on to find out more.
The best smart lock for 2023: tried and tested
Why you can trust TechRadar Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
The Nest x Yale lock is the best we've tested, although it only works with other Nest smart home products, such as the Nest Learning Thermostat and its range of home security cameras, including Nest Cam Outdoor.
Our reviewer, Christian, found that it was simple to set up and use, especially with the keypad on the outside which meant that you just punch in a code to enter your house rather than insert a key. This is great if your keys are shoved in your pockets or purse. He was also impressed with the one-touch locking feature that allowed for him to lock the door by pressing the Yale logo. Christian also found the app clear and straightforward to use too.
If you’re a HomeKit user, or a user of just about any other smart home system, you’ll have to either be fine with the lock not working with your other products, or opt for another lock altogether, though.

If you're on a budget and have a lot of house guests when you're not around, the Schalge Sense is the best smart lock for you. Why? Because the app can generate (and delete once they've been used) codes so your guests can access the property without a key.
Christian, our reviewer, also put this smart lock on test for us. He liked how easy it was to set up, and while the app isn’t the prettiest, Christian found that it works fine and you don’t even have to use it if you’re a HomeKit user (although you would benefit from it). If you do have Apple's HomeKit, you can control your lock using devices like an Apple TV, iPad, or HomePod speaker through the HomeKit app. The lock also supports Google Assistant and Amazon Alexa, allowing you to use just your voice to unlock and lock the device.
However, the Schalge Sense on the bulky side. Christian also found the app to be fiddly to use, and you'll need patience to deal with dropped connections from time to time.

The August Smart Lock Pro is one of the most discreet smart locks on the market. In fact, from the outside, you would never know it's there so it has that premium look and feel we like.
On test, Christian liked that the smart lock would automatically unlock when stood 20-30 feet from the front door, granting an easy, keyless access; although you can still use your existing keys if you'd prefer. He also liked how responsive and super easy it is to use, plus the app looks and works great, too.
You will need a Wi-Fi bridge to unlock the full potential of the August Smart Lock Pro, but the August Connect bridge is included when you purchase the lock. It's also bulkier than we would have liked, it’d be nice to have more smart home integration (in our opinion) and it's an expensive smart lock compared to the other two makes / models in this guide, but we think it's worth the investment.

Good to know
When you're searching for the best smart lock, here's some common terminology and spec that you may find good to know:
- Deadbolt style; Most smart locks come in one of two styles; deadbolt replacement or deadbolt adapter that connects to an existing deadbolt
- Trigger options; This is how you unlock your smart lock. Opt for control via: app, a code, a fingerprint or geofencing
- Smart integration; All smart locks will come with an app, but Amazon Alexa, Philips Hue, Google Assistant and HomeKit will let you control the lock plus other devices from one app
- Installation; you'll need a screwdriver to install the smart lock, and a smartphone for downloading an app to control said smart lock
How we test smart locks
To compare the best smart locks, we assess how easy they are to install and control. In addition, we evaluate how quickly they respond to commands such as locking and unlocking the door when we’re at home and no longer close by. We also check whether they integrate with Alexa, Google Assistant, or Siri and how effectively the relevant voice assistant responds to commands to control the smart lock.
We also assess each model on its ability to replace different styles of door locks, how durable it is, and the extra kit, such as hubs also available for the smart lock. We also consider whether you can use it with a key in case the Wi-Fi network, any functions that let you provide short-term access to friends and family, and that it doesn’t require reading a thick instruction manual before use.
How to choose the best smart lock for you
If you’re trying to choose the right smart lock for you, there are many considerations you should take into account before deciding on the ideal model for you.
Some smart locks connect to your smartphone using Bluetooth, which means you’ll only be able to lock the door if you’re close by. However, suppose you’re the forgetful type that struggles to remember to lock the door. In that case, a design with Wi-Fi built-in or that uses a bridge to connect to the internet and relay instructions from the cloud will ensure it can be locked or unlocked even if you’re no longer at the property.
The styling of the smart lock and whether it will fit with your current decor should also be contemplated, as there’s a wide array to choose from, including traditional-looking devices that disguise their smarts to futuristic designs with keypads and touchscreens.
Not all smart locks integrate with all voice assistants, so check if a model is compatible if you already use a voice assistant and whether it will integrate with other smart home devices you own, such as the best home security cameras, video doorbells, and smart lights.
Also, consider if you need the ability to give friends and family short-term access to the lock, and if so, does the smart lock offer activity logs so you can review who’s accessed your home and when.
If you're new to smart locks, we've also created a guide that tells you everything you need to know about smart locks.
How do smart locks work?
Smart locks are keyless devices that connect to your home Wi-Fi and can be opened by your smartphone. Some also come with a keypad so you can enter a code to unlock it too. In addition, most smart locks work with voice assistants such as Alexa or Google Assistant, so you can use your voice to open them too.
Some smart locks replace your existing lock completely, so you’ll need to be confident with DIY if you want to install them yourself, while others simply fit over the existing lock and require far less DIY.
The best smart locks can be used with smart home hubs, such as the best smart speakers and smart displays, to create home automation. For example, you can secure your smart lock and arm your home security cameras with one command or at a particular time if you’re leaving the house or perhaps going to bed. Not all smart locks will work with all voice assistants and smart home hubs, so if you already have an established smart home, check if a device is compatible before you buy.
What are the different types of smart lock?
Before you commit to which smart lock you add to your home, it's useful to look at the different options.
There are two main types of security device - deadbolt locks and multipoint locks. As you may be able to see from our list, the former is more popular and widely available, but both have their pros and cons. Both terms have been carried over from the traditional door lock world but apply in much the same way here.
Deadbolt locks are the simplest of the two, with a literal bolt that is controlled by your smart lock system and secures the door from the inside. Meanwhile, multi-point (or 'lever') locks include more than one bolt and offer a little more security. You will usually find these on more modern doors or those with a handle that must be pulled up before the door can be locked.
Generally speaking, deadbolts are easier to swap out for a smart alternative and also offer you more choices.
Do smart locks require batteries?
While most of the best smart locks come with in-built rechargeable battery packs that can usually be recharged using a USB-C cable, a few devices still require AA alkaline batteries or similar to be swapped out every so often. These are becoming less common, however, and smart locks generally don't use a huge amount of battery power at a time.
Can smart locks be hacked?
Like any internet-connected device, there is a risk that someone could hack smart locks. However, some good security practices will help minimize the risk. If there’s a default password on the smart lock, always change it and opt for a unique password, avoiding duplicating passwords from other accounts, and using a mix of upper and lower case letters, numbers, and special characters. Ensure it doesn’t contain personally identifiable information, either. Make sure your home Wi-Fi also has a strong and secure password, and the firmware for a smart lock is up-to-date.
Other good smart locks to consider
Whilst our top pick is the Google Nest x Yale smart lock (opens in new tab) - which has been our #1 since it was first reviewed in September 2021 - many of the other smart locks that you see listed in this guide would be fine, so long as they suit your needs and wants. We've had hand-on with all of the above locks but as we look to keep this guide up-to-date by continuing to review smart locks, they are a few other makes / models that should be given the time of day.
August Smart Lock gets our pick for beginners. We think that it's affordable price, nice design, and potential for upgrades make it a good starting point for anyone. It comes not only from a reliable and trusted brand but is feature-filled as well. It's got the auto-lock and auto-unlock functions, naturally, but we also love that you can create temporary guest keys, which are handy when you've got guests or staff coming in. Plus, if you're anything like us who prefer to carry light when going for a run or a hike, you can rest assured that your Apple Watch can function as your key. Read our Should I buy August Home Smart Locks? for more information.
Conexis L2 Smart Lock (opens in new tab) is a good option if you want to check-in from anywhere in the world. It's the next generation of Yale’s popular Conexis L1 Smart Door Lock which promises to be equipped with everything that you'll need to provide access to a property remotely, connecting through the Yale Access App to monitor their door from anywhere. You can even receive real-time notifications in the event that the door becomes unlocked unexpectedly.
We currently have this one in for a review, and what we're particularly looking forward to finding out is how well we get on unlocking / locking doors without a key, and using voice assistants such as Alexa to keep on the status of the front door. We're also curious to learn how easy it is to send and usual virtual keys which we can send to friends and family if, for whatever reason, we are unable to get in to the house.
Yale Sync Smart Home Alarm (opens in new tab) would be good for owners of smaller homes or apartments who would like to integrate with the Yale Smart Lock. It's a wireless alarm system that allows you to check-in from anywhere in the world and receive real-time alerts in the event your alarm is activated. There's a handy geolocation feature on the Sync Smart Home Alarm 5 Piece Kit that'll remind you to set the alarm when you leave home, giving you one less thing to worry about. You can even sync it up with Philips Hue, Google Assistant and Amazon Alexa to create the ultimate security deterrent for your home.
Note: The Conexis L2 and Yale Sync Smart Home Alarm are only available in the UK.
