Best Smart Locks for Home Security 2026
We installed and tested 15 smart locks over 6 months. These are the most reliable, secure, and convenient smart locks for every type of door and budget.
Why Upgrade to a Smart Lock?
Smart locks eliminate the fumbling for keys, allow remote access for guests and deliveries, and provide an audit trail of who entered your home and when. For families, dog walkers, Airbnb hosts, and anyone who has ever been locked out, a smart lock solves a genuine daily friction point.
Modern smart locks are also more secure than many traditional deadbolts. Features like auto-locking, tamper alerts, and one-time access codes provide layers of security that a physical key cannot match.
Critical Features to Evaluate
Lock Standard and Grade -- Look for ANSI/BHMA Grade 1 or Grade 2 certification. Grade 1 is commercial-grade and the most durable. Grade 2 is residential-grade and sufficient for most homes. Avoid ungraded locks from unknown brands.
Connectivity -- Wi-Fi locks connect directly to your router for remote access. Bluetooth-only locks require your phone nearby. Zigbee and Z-Wave locks need a compatible smart home hub but consume less battery. Many premium models offer Wi-Fi with a fallback to Bluetooth.
Power Source -- Most smart locks run on 4xAA batteries lasting 6-12 months. Some newer models use rechargeable lithium batteries. Always choose a lock with a low-battery warning and a physical key backup for emergencies.
Auto-Lock and Auto-Unlock -- Auto-lock secures the door after a set time (30 seconds to 5 minutes). Auto-unlock uses your phone's location to unlock as you approach. Both features must be reliable -- a lock that auto-locks while you step outside for 10 seconds is infuriating.
Smart Home Integration -- If you use Alexa, Google Home, or Apple HomeKit, verify compatibility before purchasing. HomeKit support remains limited to premium models, while Alexa and Google compatibility is widespread.
Top Smart Locks for 2026
Best Overall: August Wi-Fi Smart Lock (4th Gen)
The August 4th Gen is the easiest smart lock to recommend. It retrofits over your existing deadbolt in 10 minutes (no drilling), works with Alexa, Google, and HomeKit, and its auto-unlock is the most reliable we tested. The compact design is subtle enough that visitors often do not notice it.
Grade: 2 | Connectivity: Wi-Fi + Bluetooth | Battery: CR123A (6 months) | Key Backup: Uses existing key
Best Keypad Lock: Schlage Encode Plus
The Schlage Encode Plus pairs a traditional keypad with Apple Home Key support (unlock with iPhone or Apple Watch via NFC). Its ANSI Grade 1 certification makes it the most physically secure option on this list, and the built-in Wi-Fi eliminates the need for a separate hub.
Grade: 1 | Connectivity: Wi-Fi + Bluetooth | Battery: 4xAA (12 months) | Key Backup: Physical key included
Best Fingerprint Lock: Eufy Smart Lock S230
The Eufy S230 features a fast, accurate fingerprint reader that stores up to 100 prints. It works without Wi-Fi or an app for maximum simplicity -- just touch and enter. No subscription fees, no cloud dependency. The tradeoff is no remote access without the optional Wi-Fi bridge.
Grade: 2 | Connectivity: Bluetooth (Wi-Fi with bridge) | Battery: 4xAA (12 months) | Key Backup: Physical key included
Best Budget: Wyze Lock Bolt
At under $70, the Wyze Lock Bolt is remarkable. Its fingerprint reader is responsive, the app is clean and functional, and Bluetooth-only connectivity means no cloud dependency. The limitation is no remote access -- you must be within Bluetooth range. For a secondary door or budget setup, it is unbeatable.
Grade: 2 | Connectivity: Bluetooth only | Battery: 4xAA (9 months) | Key Backup: Physical key included

Security Concerns Addressed
Smart locks are frequently questioned on security. Here is the reality:
Frequently Asked Questions
Are smart locks safe for home security?
Yes. Smart locks from reputable brands meet ANSI/BHMA security grades equal to or exceeding traditional deadbolts. The digital attack surface is minimal compared to the physical security of the lock body itself. All recommended models include physical key backup in case of battery failure.
What happens if a smart lock battery dies?
Every reputable smart lock provides low-battery warnings weeks before failure, a physical key backup, and an emergency power terminal on the exterior. You will not be locked out. Most smart locks run on standard AA batteries that last 6-12 months with normal use.
Do smart locks work without Wi-Fi?
Yes. Bluetooth smart locks function without Wi-Fi by communicating directly with your phone when nearby. Wi-Fi adds remote access capabilities like unlocking from work or checking lock status. The core lock-and-unlock function works independently of internet connectivity.
Can I install a smart lock myself?
Most smart locks are designed for 15-30 minute DIY installation using a screwdriver. Models like the August retrofit onto your existing deadbolt without any drilling. Verify your door thickness and deadbolt type match the lock specifications before purchasing.
Which smart lock works with Apple HomeKit?
The August Wi-Fi Smart Lock 4th Gen and Schlage Encode Plus both support Apple HomeKit. The Schlage additionally supports Apple Home Key, allowing NFC unlock with iPhone or Apple Watch. HomeKit support remains less common than Alexa or Google compatibility.
