Ultraloq Bolt Fingerprint for $200: I have now tested three different Ultraloq smart locks over a year and a half, and while I think the company offers excellent hardware for the money, there are just a few too many software quirks that put these locks a rung below our top picks. I first began with the Bolt Fingerprint, which has been the most reliable of all the Ultraloq smart locks. If you have a standard door with a borehole for the dead bolt, it’ll be quick to install (Ultraloq has a Thick Door Kit ($10)). I initially had several issues getting the lock to connect to my Wi-Fi, but after multiple attempts and a few choice words, it connected. I’ve had no connectivity problems since. The app isn’t the prettiest, but it’s functional. You can add multiple user profiles, remotely unlock, get notifications when the doors are unlocked, share codes, and register fingerprints. There’s even an auto-unlock function for when you walk up to the door, but I found it a little inconsistent and left it turned off. The fingerprint sensor is the highlight after all. You have to get used to placing your finger on the sensor a specific way, and after doing this a few times, I’ve got it down so that I almost always unlock on the first try. It comes with a door sensor, so when the door closes, it will automatically lock (you can disable this). The next lock I tested was the Ultraloq Bolt Fingerprint with Wi-Fi and HomeKit ($140). This one did a better job connecting to my home’s Wi-Fi network through the U-Home app and was quick to add to my Google Home. Unfortunately, after several months of flawless performance, one day it decided to start rejecting my fingerprint. The problem? When I put my fingerprint on the scanner, it denied it and then blocked all other methods of unlocking except the app (or the physical key that’s included). This was so annoying that I just stuck to using a numerical code with the keypad. Finally, I recently switched to the Bolt Fingerprint With Matter ($200), and let’s just say I’m still diagnosing issues with the company. The lock decides to stop working after a few hours, forcing me to remove one of the batteries and put it back in to “reactivate” it. I might just have a defective unit, so we’ll see. —Julian Chokkattu
Ultraloq U-Bolt Pro for $120: WIRED reviewer Julian Chokkattu also tested the U-Bolt Pro from Ultraloq, which uses the same app that the Fingerprint models do. He says it took a few attempts to connect to Wi-Fi, but once connected it worked well with no Wi-Fi issues during the year he tested it. It has built-in Wi-Fi, uses four AA batteries that last around two months (less in super cold weather), and has a hidden mechanical keyhole as a backup in case the battery dies when you’re not home, and you get two spare keys. There’s a charging port underneath so you can give it some juice during emergencies if the lock is dead and you don’t have the key, but we wish it were USB-C instead of Micro USB. It’s a good lock, but he prefers the Fingerprint models since it has a nicer build quality and it has eight batteries, so the lock lasts twice as long.

Yale Assure Lock 2 Touch for $300: I’ve been testing this lock for a few weeks in tandem with ADT’s security system and Google Home. Unlike the other locks in this guide, I didn’t install it—an ADT tech did, and installation can be included in an ADT security package like the one I’ve been testing. For the lock itself, it’s worked well. It’s a full dead-bolt replacement, and came with a single key, and has both a keypad and fingerprint reader for entry options. The fingerprint reader is speedy and efficient, and my husband says the keypad has been easy to use (you activate the keypad by touching the Yale button, but if your finger is registered to the app, that’s also the fingerprint reader button). Instead of using the Yale app, I primarily control this app with the ADT+ app, but there are versions of this lock that don’t use or require ADT’s service. I do wish I could set it to lock after every 10 minutes, rather than three, but that’s the longest option the ADT+ app gives me to set it. I can also partially control it in the Google Home app, but only to lock and unlock it, not to dive into detailed settings like passcodes and auto-lock times.
Yale Assure Touchscreen Lever Lock for $249: I’ve been testing this no-dead-bolt lever door handle with its sleek-looking keypad for about seven months on the door to my house from inside my garage. Unlike Yale’s Approach Lock, it won’t sense you coming, but it awakens with even a light touch to the keypad. It’s easy to lock and unlock and view the activity log on the Yale Access app, or you can use a pin code to unlock. You can also create different codes for different people to know exactly who’s been coming and going and when. It works with Google Home, Apple Home, and Alexa, and has also got two physical keys for backup in case of battery failure. Setup wasn’t exactly a breeze, requiring the Bilt app to install and then the Yale app to configure, and online reviews are quite voluminous in their complaints of both battery life and the handle becoming loose over time. Neither of these issues has arisen during our test period; however, we will update this review with further observations as time goes on. —Kat Merck
Avoid These Smart Locks
We haven’t loved every smart lock we’ve tried. These are the ones to skip.
Eufy FamiLock S3 Max for $350: This lock is cool because it includes a camera, letting the device double as a digital peephole (convenient for smaller family members!) and has a super interesting biometric option that uses the veins in your palm for authentication. Unfortunately, once installed, the lock didn’t work on my door, even though it was the correct size and placement.
