The best smart lock 2022 – chosen by our experts
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 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.
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.
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 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.
