A smart lock is one of the rare smart home upgrades that pays off the moment it's installed — no more digging for keys, no more spare keys hidden under the mat, and the ability to let someone in remotely without being home. But the category spans a huge range, from $79 keypad deadbolts to $349 locks with facial recognition, and the right one depends heavily on whether you own or rent, how tech-integrated you want your entryway to be, and how much you're willing to spend for extra convenience.
We compared four smart locks that each serve a different kind of buyer. The Wyze Auto-Lock Bolt v2 is our Best Value pick — a full fingerprint smart deadbolt for under $80. The Schlage Encode is our Best Overall pick, the most trusted, most-reviewed smart lock on Amazon with over 16,000 ratings. The August Home Wi-Fi Smart Lock is our pick for renters, since it installs over your existing deadbolt and keeps your original keys working. And the Lockly Visage Zeno is our Premium Pick, with facial recognition and Apple Home Key support for buyers who want the most advanced entry experience available.
We evaluated each lock on installation difficulty (can you do it yourself with a screwdriver, or does it require real modification), security certification (BHMA and ANSI ratings matter more here than marketing claims), smart home compatibility (Alexa, Google, Apple Home, Matter), and real-world reliability based on customer reviews. The Wyze Auto-Lock Bolt v2 has become the #1 Best Seller in its Amazon category with a 4.6-star average across 532 ratings. The Schlage Encode is the heavyweight of the group with 16,560 ratings at 4.3 stars and 4,000+ bought in the past month alone. The August Home Wi-Fi Smart Lock holds 10,709 ratings at 4.1 stars. And the Lockly Visage Zeno holds a 4.5-star average across 387 ratings, with 300+ bought in the past month.
Quick Notes
The Wyze Auto-Lock Bolt v2 is our Best Value pick because it delivers a full fingerprint smart deadbolt for $79 while holding a 4.6-star average across 532 ratings and the #1 Best Seller spot in its Amazon category. It's aimed at anyone who wants real smart lock functionality without spending real money on it. One concrete detail that matters is the AI-learning fingerprint scanner, which gets faster and more accurate the more it's used — reviewers consistently describe unlock times of about half a second once the system has learned their print. A second detail is the USB-C emergency power port, which lets you power the lock with any common power bank if the internal batteries die, avoiding the lockout risk that comes with locks that only support proprietary backup power. The tradeoff is that some reviewers noted difficulty registering fingerprints for older users or those with worn fingerprints, though the keypad and app both work as reliable backups. Skip this one if you need Apple Home Key or facial recognition. Buy it if you want a genuinely capable smart lock without spending much.
Quick Notes
The Schlage Encode is our Best Overall pick because it combines 16,560 ratings at a 4.3-star average with the broad trust that comes from over a century of Schlage manufacturing experience. It's built for buyers who want the single most reliable, most widely adopted smart lock available. One concrete detail that matters is the built-in Wi-Fi, which connects directly to your home network without requiring a separate hub — a real advantage over locks that need an additional bridge accessory to enable remote access. A second detail is the certified highest residential security, durability, and finish rating from BHMA industry experts, combined with a built-in alarm that detects forced entry attempts — a level of certified security most competitors in this price range don't match. The tradeoff is that a few reviewers reported occasional Wi-Fi connectivity hiccups, though the lock continues to function manually and via touchscreen even when disconnected. Skip this one if you're renting and can't replace your exterior hardware. Buy it if you want the single most trusted, most reliable smart lock available.
Quick Notes
The August Home Wi-Fi Smart Lock is our pick for renters because it installs entirely on the inside of your door over your existing deadbolt, holding 10,709 ratings at a 4.1-star average. It's built for anyone who wants smart lock convenience without being able to change their exterior hardware. One concrete detail that matters is that it fits over most single-cylinder deadbolts in about 10 minutes, keeping your original exterior keyhole and keys fully functional — your landlord, roommate, or property manager can still use their existing key at any time. A second detail is DoorSense, a sensor that tracks whether your door is actually open, closed, locked, or unlocked, and feeds that into an activity log so you always know your door's real status, not just where the lock last thought it was. The tradeoff is battery life — multiple reviewers note it can drain batteries faster than expected with heavy use of auto-lock and auto-unlock features, so keeping a spare set of CR123A batteries on hand is worth it. Skip this one if you own your home and want a full exterior deadbolt replacement instead. Buy it if you're renting and need to keep your existing keys and door hardware.
Quick Notes
The Lockly Visage Zeno is our Premium Pick because it delivers facial recognition unlocking backed by a 4.5-star average across 387 ratings, with 300+ bought in the past month. It's built for buyers who want the most advanced, most convenient entry experience available and are willing to pay for it. One concrete detail that matters is the dual infrared facial recognition sensor, which unlocks the door in about a second as you approach, works accurately in any lighting including full darkness, and stores facial data encrypted locally on the device rather than in the cloud. A second detail is the PIN Genie keypad, which shuffles the digit positions on every use so a code can't be guessed by watching finger placement — a real security upgrade over standard static keypads. The tradeoff is price and setup complexity — at $349 it's the most expensive lock here, and a handful of reviewers reported needing a firmware update or support call to get Wi-Fi features fully working. Skip this one if you just want a straightforward, no-frills smart lock. Buy it if you want the most advanced unlocking experience in this lineup and don't mind paying for it.
