eufy Smart Lock – When you hear the name Eufy, you might not immediately picture door locks; however, the company is best known for its robotic vacuum cleaners, though it also produces an increasing number of other innovative home accessories.

However, your brand-new Eufy Smart Lock is exceptional for two reasons: Its versatility in the various ways you can lock and unlock comes first. You can enter text using a keyboard, a digital assistant, an in-screen fingerprint scanner, the Eufy Security smartphone app, or a regular key. Second, it is one of a few, but increasingly, smart locks that have an integrated Wi-Fi radio (no hub or bridge required).

The most reputable lock companies, Kwikset and Schlage, introduced the first Wi-Fi lock models with the $229 Kwikset Halo and the $250 Schlage Encode. The new Eufy lock costs about the same as these models, but it has a fingerprint reader. The latest Kwikset Halo Touch model lacks the keypad and is the only central Wi-Fi smart lock with a fingerprint scanner.

Install eufy Smart Lock

Over the years, I’ve installed six intelligent locks, but this was the first time with a rechargeable battery (most use AA batteries). On the one hand, a rechargeable battery is excellent from a durability standpoint. On the other hand, however, on the flip side, you can’t pop in a few batteries and get going right away.

So please keep in mind: You’ll need to give the battery an initial charge of 6 hours before installing the lock. I was eager to try it right out of the box, so it was a bit frustrating knowing I had to wait 6 hours. But that’s not unreasonable, of course, with a rechargeable battery.

I could install the lock with a charged battery in less than 30 minutes. The only tools he needed were a Phillips screwdriver and a tape measure. The process was easy, and I had no problems. Additionally, Eufy offers a ton of instructions. Along with written instructions and an installation video in the Eufy Security app, a printed installation manual is also provided in the box.

One last thing to note about the rechargeable battery: your lock will only work with a physical key while you’re charging it. Your only other option is to connect a portable battery to power the safety while the battery recharges temporarily. (Eufy’s sister brand, Anker, sells a variety of portable batteries.) Eufy says it will soon offer spare batteries, so having two would allow you to swap out a charged battery while recharging a drained one.

For the intelligent lock model T8520, please remove the rechargeable battery from the smart lock before charging. A 5V/2A charger is also recommended to charge the battery fully.

As its name suggests, the eufy Smart Lock circumvents the biggest flaw of its Bluetooth-only predecessor, the lack of an internet connection, to add critical features such as remote control, voice control and notifications, making it a worthy rival—smart locks from more established brands.

It was easy to install, configure and use and quick to lock and unlock. No more searching for keys or even remembering a keypad code. It felt like a premium lock, even though Eufy is mainly associated with budget robot vacuums. Of course, we’ll have to buy it and bring it to our door lock testing lab to see if this new lock can perform well in our ratings like its sister.
