Your front door is the gateway to your home β and your family's safety. Smart door locks eliminate the worry of lost keys, enable remote access for guests, and let you monitor who comes and goes. After testing the top models of 2026, we've found the best smart locks for every home, budget, and security need.
Why Upgrade to a Smart Door Lock?
Traditional locks rely on physical keys that can be lost, copied, or stolen. Smart locks offer keyless entry via PIN codes, fingerprints, smartphone apps, or even voice assistants. You can create temporary codes for guests, receive instant alerts when someone enters, and lock or unlock your door from anywhere. Many smart locks also integrate with your existing smart home ecosystem β your porch camera can unlock the door when you arrive, or your smart lighting can simulate occupancy when you're away. For renters, retrofit smart locks install over your existing deadbolt in minutes without any drilling.

How We Tested
We installed each smart lock on a standard residential door and tested them over 30 days in real-world conditions. We evaluated: ease of installation (including for renters), fingerprint recognition speed and accuracy, app responsiveness and reliability, battery life over typical use, and how well each lock integrated with Alexa, Google Home, and Apple HomeKit. We also tested physical security features, deadbolt strength, and resistance to forced entry.
Buying Guide
1. Retrofit vs. Full Replacement
Retrofit smart locks (like August) install over your existing deadbolt β no drilling, no hardware changes, and perfect for renters. Full replacement locks (like Schlage Encode) swap out the entire deadbolt and offer a more integrated look but require more involved installation.
2. Entry Methods
Most smart locks offer multiple entry methods: app control, keypad/PIN code, fingerprint, physical key backup, and voice assistant integration. Fingerprint scanners are the fastest (unlock in under a second on premium models), while PIN codes work well for guests and service providers.
3. Smart Home Integration
If you use Alexa, Google Home, or Apple HomeKit, make sure your lock is compatible. Matter-supporting locks offer the broadest ecosystem compatibility. Look for locks that can trigger automations β like turning on lights when you unlock the door at night.
4. Battery Life & Alerts
Most smart locks run on 4 AA batteries and last 6-12 months depending on use. Look for low-battery alerts via app and email. Some locks have a physical key backup; others rely entirely on batteries β consider whether you want a failsafe key option.
5. Auto-Lock & Auto-Unlock
Auto-lock automatically re-locks the door after a set period (typically 30 seconds to 5 minutes). Auto-unlock uses your phone's location to detect when you arrive home and unlock automatically β incredibly convenient when your hands are full.
Frequently Asked Questions
Are smart locks secure?
Yes β quality smart locks from reputable brands meet ANSI/BHMA Grade 2 or Grade 1 standards for physical security. The encryption used by major brands (AES-128 or higher) makes them resistant to hacking. The biggest security risk is weak PIN codes, so use unique codes and avoid obvious combinations like 1234.
Can smart locks be hacked?
Any connected device carries some risk, but major brands use bank-level encryption and two-factor authentication. To minimize risk: use a strong unique password for the lock's app, enable 2FA if available, keep firmware updated, and use a secure home WiFi network.
What happens if the battery dies?
Most smart locks alert you well before the battery dies. If it does die, nearly all models have a physical key backup. Some premium models also have a 9V battery terminal on the exterior that lets you temporarily power the lock to enter your code.
Do smart locks work with existing deadbolts?
Retrofit locks like August and Wyze Lock work with your existing deadbolt β you keep your current keys and only replace the interior thumb-turn. Full replacement locks require swapping the entire deadbolt assembly.
Can I still use a physical key?
Most smart locks retain a physical key cylinder as a backup. Some slim-profile locks and deadbolt-only models skip the key backup, so check before buying if key access is important to you.
Final Verdict
For most homeowners, we recommend the Aqara Smart Lock U200 as our top pick β it combines seamless installation, reliable fingerprint and app control, and broad smart home compatibility. Renters and those who want a quick install should consider the August Wi-Fi Smart Lock (4th Gen) for its effortless retrofit design. Premium buyers wanting the best of the best will love the Schlage Encode Plus for its built-in camera and video doorbell functionality.
