August Wi-Fi Smart Lock - Best Overall
The August Wi‑Fi Smart Lock attaches to the interior side of your existing deadbolt, preserving the original keyhole for backup access. It supports 256‑bit AES encryption, works with Alexa, Google Assistant and Apple HomeKit, and offers auto‑unlock when your phone approaches. The lock features a 4‑digit passcode entry, a built‑in alarm that sounds after five failed attempts, and a rechargeable battery that lasts up to six months under normal use.
Schlage Encode Smart WiFi Deadbolt - Best Budget
Schlage Encode combines a traditional deadbolt feel with Wi‑Fi connectivity, eliminating the need for a separate bridge. It includes a keypad for up to 100 user codes, a built‑in alarm, and a steel deadbolt rated to resist forced entry. The lock integrates directly with Ring doorbells and major voice assistants, and it ships with a two‑year battery warranty. At its price point, it delivers solid security without sacrificing convenience.
Yale Assure Lock SL - Best for Minimalist Design
Yale’s Assure Lock SL is a key‑free, low‑profile deadbolt that blends a sleek touchscreen with robust security. It supports Z-Wave Plus and can be paired with the Yale Secure app, allowing remote locking, guest code management and activity logs. The lock’s motorized deadbolt offers smooth operation, and its battery life reaches up to 12 months with standard AA cells. Its modern aesthetic makes it a popular choice for contemporary interiors.
Kwikset Halo Touchscreen Deadbolt - Best for Simple Installation
The Kwikset Halo Touchscreen Deadbolt is designed for DIY installation, fitting most standard doors without extra drilling. It provides a backlit touchscreen for up to 30 user codes, Bluetooth Low Energy for smartphone control, and a tamper‑resistant alarm. The lock’s SmartKey rekey technology lets you change the lock’s core in minutes, a useful feature for renters or frequent movers. Battery life averages nine months on a single set of AA batteries.
Eufy Security Smart Lock Touch - Best for Battery Longevity
Eufy’s Smart Lock Touch stands out with its 12‑month battery claim, backed by a low‑power ARM processor and an energy‑saving sleep mode. It offers a capacitive touchpad for up to 100 user codes, Bluetooth 5.0 for fast phone pairing, and optional Wi‑Fi bridge (sold separately) for remote access. The lock also features an auto‑relock function, an anti‑pick shield and a weather‑proof rating suitable for front doors in any climate.
What to look for
What to consider
When selecting a smart lock, start by checking the lock’s compatibility with your existing deadbolt and door thickness. Some models, like August, mount over the existing hardware, while others replace the deadbolt entirely and may require a new strike plate. Consider the connectivity options you need - Wi‑Fi provides direct remote access, whereas Z‑Wave or Zigbee require a hub but can integrate with broader home automation systems.
What to consider
Battery life is another critical factor. Locks that use rechargeable lithium cells, such as August, need occasional charging, while AA‑powered models like Yale and Eufy offer longer intervals between replacements. Finally, evaluate the user management features: guest codes, temporary access, and activity logs can be essential for families, Airbnb hosts or anyone who wants detailed security insight.
