A lock is one of the few household purchases where a mistake stays with you for years, so this rating collects smart lock brands that have proven themselves on real doors. It is meant for anyone weighing a first keyless deadbolt, for a landlord tired of cutting spare keys, and for households that would like to stop hiding one under the mat.
Selection looked at what actually costs money over time: hardware price, whether remote access needs an extra hub or module, battery type and how quickly it drains, warranty terms, and how simple it is to reach a live person in support. Build quality counted as well, including published ANSI/BHMA grades, weather resistance, and whether the lock lets you keep your existing keys. Among smart lock brands the differences show up in the accessories, so bundles and add-ons were priced in too.
Places are decided by community votes, not by the editors and never by payment. Read the plus and minus lists in each card, then the reviews under it: dead batteries, firmware bugs and app outages appear there long before they reach a spec sheet. If you already live with one of these locks, vote and add what the marketing pages leave out.
The Yale name goes back to 1840 and the brand now belongs to ASSA ABLOY, which explains the wide catalogue: keypad and touchscreen deadbolts, key-free versions, the Assure Lock 2 family, and the Approach retrofit unit that mounts over an existing deadbolt and keeps your old keys. Connectivity is modular, so the same lock body can run Wi-Fi, Z-Wave or Matter depending on which module is fitted, and a key-free model removes the cylinder entirely for anyone worried about picking.
Sensible for owners who want one brand across several doors and are willing to pay roughly two hundred dollars a lock. Renters are better served by the Approach or by a retrofit brand, since swapping a full deadbolt usually needs the landlord's blessing. Note that the module you need is often sold separately, so compare bundle prices before ordering.
August made retrofit locking mainstream in 2013 and has been part of ASSA ABLOY since 2017. The mechanism clamps onto the inside of a standard single cylinder deadbolt, so the outside of the door does not change and every existing key still works, which is why the brand is popular with tenants. The fourth generation Wi-Fi Smart Lock is noticeably smaller than earlier discs and connects without a separate bridge; DoorSense tells the app whether the door is actually shut, not merely locked.
A good fit for a rented flat, a shared entrance or anyone who dislikes drilling. Less suitable if you want a keypad on the door itself, because that is a separate accessory, and it will not help on mortise or multipoint European doors. Battery life depends heavily on how often auto-unlock triggers.
Part of Allegion, Schlage is the brand locksmiths tend to name first when the conversation turns to residential security ratings: most of its deadbolts carry BHMA Grade 1, the highest residential class, and that shows in the weight of the metal. The Encode line puts Wi-Fi inside the lock with no hub or bridge, while Encode Plus adds tap to unlock with a phone or watch through Apple Home Key. Codes are managed in the app and can be issued as temporary or recurring.
Worth the money on an exposed front door where forced entry, not gadgetry, is the real concern. The trade-off is size: the keypad escutcheon is large and the interior housing is chunky, so it suits solid entry doors better than slim glass panelled ones. Four AA batteries, and Wi-Fi models eat them faster than Bluetooth ones.
Kwikset, a Spectrum Brands hardware label, is the value end of the American deadbolt aisle and the home of SmartKey Security, a rekeying system that lets an owner match a new key in under a minute without a locksmith. That single feature saves real money in a house that changes tenants or contractors. The smart range runs from the Bluetooth-only Aura through the Wi-Fi Halo keypads to Z-Wave models for alarm panels, usually undercutting comparable Schlage units by a noticeable margin.
Reasonable for a back door, a garage entry or a rental where several locks must key alike. Buyers focused on maximum resistance to attack should read the security grade on the specific model rather than assume, since much of the line sits at Grade 2 or 3. Finishes are broad, so matching existing handles is rarely a problem.
Level took the opposite path to everyone else: the motor, radio and battery live inside the deadbolt bore, so from the hallway the door looks completely ordinary. The visible parts are conventional thumb turn and cylinder, the keys keep working, and there is no plastic box on the inside face. Level Lock+ adds Apple Home Key, letting an iPhone or Watch unlock by touch, and the whole assembly runs on a single CR2 cell that typically lasts about a year.
The obvious choice for anyone who refuses to spoil a nice door, and for households already inside Apple Home, which supplies the hub for remote access. Bluetooth is the native radio, so away-from-home control depends on that hub or on Level's own connect accessory. There is no keypad on the door unless you buy the touch accessory.
Aqara belongs to the Shenzhen company Lumi United and treats the lock as one node in a large smart home catalogue of sensors, hubs, cameras and switches. The door lock range covers retrofit and full deadbolt formats, with fingerprint readers, NFC cards, PIN pads and Apple Home Key on the U100 and U200. Pricing usually lands below the American brands for the same feature list, and automations run locally through an Aqara hub rather than depending on a distant server.
Attractive for a household that wants sensors and lighting from the same app and values fingerprint entry for children or older relatives. Fit checks matter: several models are designed around US deadbolts, others around Asian or European door styles, so measure before buying. Support is handled by email and forum rather than a phone line.
SwitchBot began with a small robot that pressed physical buttons, and its locks follow the same philosophy: the unit sits over the existing thumb turn and turns it for you. Installation takes minutes with adhesive and needs no cylinder change, which makes the Lock, Lock Pro and Lock Ultra unusually renter-friendly. A separate Keypad Touch adds codes and fingerprints outside the door, and a SwitchBot hub brings remote access and Matter support for Apple, Google, Amazon and Samsung systems.
Practical where drilling is out of the question and the door already has a normal thumb turn. Not the pick for a showpiece entrance, since the module is a visible block on the inside. Anyone wanting away-from-home control should budget for the hub as well, otherwise the lock stays a Bluetooth device.
U-tec, based in Milpitas, California, sells its locks under the Ultraloq name and built its reputation on packing many entry methods into one affordable body. The U-Bolt Pro line offers fingerprint, PIN, mechanical key, app, auto-unlock and voice assistant access, with the reader responding in well under a second, while the Bolt Mission adds a solar panel to top up the battery from daylight. Prices typically sit between the discount keypads and the premium American deadbolts.
Sensible for a family that wants everyone to have a different way in: a fingerprint for the teenager, a code for the cleaner, a key in the drawer for emergencies. Less convincing for buyers who judge a lock by metalwork, since finishes and internal parts feel lighter than Schlage. Firmware updates arrive often, which is good news and occasionally an inconvenience.
eufy is Anker's smart home line, and its selling point is subscription-free operation: fingerprints, codes and recordings are handled on the device rather than behind a paywall. The lock range spans plain keypad deadbolts such as the C210 and C220 up to video models that combine a 2K camera, doorbell and lock in one unit, so a narrow porch can lose one device instead of gaining three. Fingerprint matching is done locally and takes a fraction of a second.
Good value for households that already own eufy cameras and want everything in one app without monthly fees. The combined video locks are large and demand a suitable door frame, so measure the stile before ordering. Worth knowing that the brand handled a cloud thumbnail privacy incident in 2022, after which its documentation on encryption became far more detailed.
Nuki is an Austrian manufacturer from Graz, founded in 2014, and it solves a problem the American brands ignore: European doors with profile cylinders and multipoint mechanisms. The lock mounts over the inside cylinder knob, keeps the original key usable from outside, and the Pro and Ultra versions bring Wi-Fi and Matter over Thread without an extra bridge. A keypad with fingerprint, a door sensor and an opener for building entry systems complete the set.
The natural candidate for flats in Germany, Austria, Switzerland, the Netherlands and neighbouring markets, and popular with short-term rental hosts thanks to integrations with booking and property management platforms. Pointless for a standard US deadbolt door. The motor is audible, which some owners in quiet hallways find annoying at night.
