The security-conscious will already have thought of security cameras and alarms as ways to keep their home safer, but the best smart locks are fast becoming the next big thing in home security.
Not only do they allow you to control better who comes in and out using just your smartphone, but they can also supplement existing security features already installed around the home.
Smart locks allow homeowners to keep their properties safe from intruders but grant access to those who need it, such as cleaners, babysitters, or even Airbnb guests, without leaving your home open to unwanted visitors. But, of course, it also means that you won't be locked out the next time you forget your keys!
We've taken a look at some of the best and most popular smart locks available right now, rating them on their reliability, connectivity, and design.

The best smart locks: our top picks
Why you can trust Real Homes
eufy is known for its reliable and budget-friendly smart home products and has added a high-end smart lock to its offerings. The eufy Security Smart Lock Touch gives users several ways to unlock their door - via the smartphone app, the fingerprint sensor, or a passcode - adding to peace of mind and security.
The big selling point of the eufy smart lock is its fingerprint sensor, which works brilliantly once set up. The programming process is the same as for the fingerprint sensor on a smartphone (pressing and lifting your finger several times until it gets a good reading). Once it knows you, you'll be able to open the lock in double-quick time simply by pressing your finger to the interface.
This is also useful for viewing the history of the lock (available through the app), as it knows exactly who has been in and out based on the fingerprint used. Each user can also be given a unique passcode.
The only real drawback we found with the smart lock is the tricky installation process. It should be expected given how many things eufy's product allows you to do but, despite the detailed instructions provided, it is more labor-intensive and time-consuming than we anticipated. That said, once we did it, the result was sleek and solid enough to justify it.
The eufy Security app allows you to adapt settings to your requirements, including sounds the lock makes and granting temporary access when someone outside your household needs to enter. It's also straightforward to set schedules and add users quickly.
