Smart locks have come a long way in recent years and are now incredibly easy to install and use. Gone are the days of drilling holes in your door and wondering whether the lock would actually open when triggered. The best modern locks can be fitted over your existing deadbolt, and are fast, quiet, and dependable. They work seamlessly with the rest of your smart home tech, and are so convenient that they just blend into the background.

• Prime Day smart lock deals in the UK
It can be tricky deciding which one to buy, though, so I’ve put together a quick roundup of the three best models we’ve tested in the last year. Smart locks are usually region-specific, so if a particular model is only available in the US, I’ve recommended a comparable model for UK home-owners — and vice versa.
Best of all, every lock in this listing is on special offer for Amazon Prime Day, with most of them down to their lowest prices ever.
1. Lockly Visage Zeno Series Smart Lock
The best smart lock we’ve tested for homeowners in the US, the Lockly Visage Zeno Series is a good-looking, streamlined device that you’ll be proud to have on your front door, and is noticeably smaller than previous models.
It’s a piece of cake to install and use as well, particularly when integrated with Apple HomeKit. Our reviewer, Lance Ulanoff, who awarded it an impressive four and a half stars out of five, praised its on-board Wi-Fi, which means you don’t need a separate hub, and the way Apple Home Key allows for proximity unlocking; pull up in your driveway, and the lock will open automatically, when the appropriate setting is enabled. It just makes life easier, which is the whole point of a smart lock.
Lance and his partner were impressed by the way FaceID “just works” with the Visage Zeno Series, and fingerprint recognition proved well-implemented as well. It’s even quieter than most other smart locks, adding to the whole premium experience.

The Visage Zeno Series is usually one of the more expensive smart locks around, but this Prime Day deal makes it much more affordable. This is the cheapest it’s ever been by quite a wide margin.View Deal
There aren’t many smart locks with facial recognition for UK homes, but SwitchBot has you covered. Its latest Matter-enabled smart lock is down to its lowest-ever price for Prime Day.View Deal
2. Ultion Nuki 2025
Our reviewer James Day called the Ultion Nuki 2025 “the most well-rounded smart lock available in the UK right now” when he tested it earlier this year, explaining that it removes the friction that usually turns people off the idea of smart home security. Built-in Wi-Fi means there’s no need for a separate hub, it’s easy to install, and it responds almost instantly when triggered.
Its app is well-designed too, and support for the Matter standard means it will work nicely as part of a mix-and-match smart home
It carries anti-pick, anti-bump, and anti-drill credentials, meets Police Preferred specification, holds Master Locksmiths Association approval, and is backed by a £5,000 burglary guarantee, which Brisant says it has never had to pay out on.
This particular Nuki lock is designed for UK doors — if you’re in the US, take a look at the Nuki Smart Lock & Keypad 2, which is very similar in terms of looks and features, and is now just $198.50 (was $269) for Prime Day.

Amazon has knocked a generous £70 off this premium smart lock for Prime Day, bringing it down to a record-low price (it was £300 for a few days earlier this year, but the price soon bounced back up).View Deal
If you’re in the US, this Matter-enabled smart lock is a great option, mounting on top of your existing deadbolt for easy installation. Like the UK model, it’s down to a record-low price for Prime Day.View Deal
3. Yale Linus Smart Lock L2 Lite
Yale is one of the biggest names in smart locks, and is offering great Prime Day deals on locks for all types of doors in the US and the UK.
The Linus Smart Lock L2 Lite is made for the British market and fits over your existing lock cylinder, so there’s no need to drill, making it a sensible choice for renters and anyone else who’s apprehensive about taking power tools to their front door. It supports Matter-over-Thread, so it’ll work nicely with the rest of your smart home devices, and there’s no Yale-specific bridge necessary.
In use, our reviewer found it “unremarkable, in the best way”. It simply works, responding quickly to app and voice commands, and its auto-unlock feature proved a great time-saver. The motor isn’t silent (it whirrs in a business-like manner), but there’s no lag, and it’s effortless to use.

If you’re in the US, take a look at this high-quality smart deadbolt from Yale, which is almost half price in the Prime Day sale. It can be installed on most doors with nothing but a screwdriver, and can be secured in four different ways.View Deal
