The August WiFi Smart Lock wins on versatility — it converts your existing deadbolt without replacing your keys. Auto-unlock as you approach is genuinely useful, and the broad smart home compatibility is unmatched.
The Assure Lock 2 is the most future-proof smart lock available — Matter-over-Thread ensures it will work with every smart home ecosystem for years to come. Yale's reputation for deadbolt security is a bonus.
Schlage Encode Plus is the gold standard for security-conscious iPhone users. Grade 1 ANSI rating plus Apple Home Key (tap iPhone to unlock) makes it the most secure and premium Apple HomeKit lock available.
Level Lock+ is the only smart lock that's completely invisible — the entire mechanism lives inside the deadbolt. Renters love it because it leaves no visible trace. Apple Home Key is the cherry on top.
Ultraloq's U-Bolt Pro WiFi delivers the most flexible access methods at the lowest price. The fingerprint reader is fast and accurate even in cold weather — a common failure point for competitors.
The Kwikset Halo is the easiest upgrade from a traditional deadbolt to a smart lock at a budget-friendly price. Built-in WiFi and SmartKey rekey technology are standout features at this price point.
The Lockly Visage is the most futuristic smart lock on the market with 3D face recognition. The randomized PIN pad is genuinely clever security engineering. Reliability has improved with firmware updates but still trails top competitors.
The Eufy C220 delivers fingerprint access and no subscription fees under $100. Local fingerprint storage means it works without the internet — a real advantage for reliability and privacy.

Smart locks in 2026 split into two camps: retrofit models that replace only the interior side of your deadbolt, and full replacement deadbolts with an exterior keypad, fingerprint reader, or face scanner. The bigger change is connectivity. Built-in Wi-Fi is now common, so many locks no longer need a separate bridge for remote access, while Matter and Thread support let one lock work across Apple Home, Google Home, and Alexa. Apple Home Key, which unlocks with a tap of an iPhone or Apple Watch, has spread from Schlage to Level and Kwikset models.
The most common mistake is buying for features before checking the door. Retrofit locks such as the August WiFi Smart Lock only fit certain single-cylinder deadbolts, and invisible locks like the Level Lock Pro replace the bolt itself, which matters if your door has an unusual backset or thickness. Measure the door and check each maker's compatibility tool first. Another frequent mistake is ignoring the hub question. A lock described as Matter or Thread compatible may still need a Thread border router, such as a recent Apple TV, HomePod, or Nest hub, before remote access works.
Batteries are the other hidden cost. Manufacturer ratings range from about three months for the August WiFi Smart Lock on two CR123 cells to around eight months for the Eufy Smart Lock C220 on eight AA cells, and Wi-Fi use usually shortens those figures. Locks that run over Thread tend to draw less power than those on Wi-Fi. Finally, read BHMA grades carefully. Newer locks are often rated under the A156.40 residential standard with AAA, AA, or A grades, while older listings cite Grades 1 to 3, so compare like with like.
A retrofit lock like the August WiFi Smart Lock keeps your existing exterior hardware and keys, which suits renters and anyone who likes their current deadbolt. A full replacement lock adds a keypad, fingerprint reader, or face scanner outside, so guests and kids can get in without a phone.
iPhone households get the most from locks with Apple Home Key, such as the Schlage Encode Plus and Level Lock Pro, because an iPhone or Apple Watch works like a key card. Android and Alexa users should prioritize Matter support or a strong native app instead.
Focused recommendations for specific needs
Built-in Wi-Fi gives remote access without extra hardware but usually drains batteries faster. Thread and Matter-over-Thread locks are more power efficient but need a compatible border router, and some locks need a separate bridge, such as Level's $79 Connect, for remote access.
Count how people actually come in. Keypads with many user codes suit families and short-term rentals, fingerprint readers suit people who forget codes, and face recognition, as on the Lockly Visage, is hands-free but costs more and needs frequent charging according to reviewers.
Check both the rated life and the cell type, since AA batteries are cheap and easy to find while CR123 and CR2 cells cost more. A rechargeable pack or an emergency USB power port prevents lockouts when the battery dies.
Look for a BHMA rating on the spec sheet and compare it to the door you are securing. A Grade 3 lock like the Eufy Smart Lock C220 is fine for many homes, but a busy main entry benefits from a higher-rated deadbolt.
The August WiFi Smart Lock ranks first because it adds remote access, auto-unlock, and door-position sensing while keeping your existing deadbolt and keys. The Yale Assure Lock 2 is the better pick if you want a full keypad deadbolt with broad smart home support, and the Schlage Encode Plus is the strongest choice for iPhone users who want Apple Home Key.
Many current models, including the August WiFi Smart Lock, Schlage Encode Plus, Ultraloq U-Bolt Pro WiFi, and Eufy Smart Lock C220, have built-in Wi-Fi and need no bridge. Thread-based locks such as the Level Lock Pro need a Thread border router or Level's Connect bridge for remote access.
It varies widely by model and connection type. August rates its WiFi Smart Lock at up to three months on two CR123 batteries, Eufy rates the C220 at about eight months on eight AA batteries, and Level cites roughly nine to twelve months from a single CR2 for the Lock Pro. Heavy Wi-Fi use shortens battery life.
A retrofit lock is the safest option for renters because it replaces only the interior thumb turn and leaves the exterior cylinder and keys alone. The August WiFi Smart Lock works this way, so you can reinstall the original part when you move out. Check your lease before changing any lock.
Home Key stores a digital key in Apple Wallet so you can unlock by holding an iPhone or Apple Watch near the lock. In this ranking the Schlage Encode Plus and Level Lock Pro support it. Schlage lists iPhone XS or later with iOS 15 or later as the minimum, and an Apple TV or HomePod home hub is needed for remote control.
Most do. The Schlage Encode Plus, Yale Assure Lock 2 keyed versions, Kwikset Halo, Ultraloq U-Bolt Pro WiFi, and Eufy Smart Lock C220 include a key cylinder as a backup, and the August WiFi Smart Lock keeps your existing key. Key-free versions rely on backup power ports instead.
Reviewers generally report fast, accurate reads on dry fingers, but wet, dirty, or very cold fingers can cause failed attempts. That is why fingerprint locks such as the Ultraloq U-Bolt Pro WiFi and Eufy Smart Lock C220 also offer a keypad and app unlock as backups.
