Smart Locks Buying Guide (2026): What Matters and 8 Picks

What to Look for in Smart Locks

Connectivity type

Wi-Fi locks connect directly to your home network, removing the need for a separate hub. This simplifies setup and allows remote control from anywhere. Products like the Schlage Encode and Philips 4200 Series use this method. Keypad-only models, such as the TEEHO or Kwikset Powerbolt, operate offline. They lack remote features but avoid network dependency. Choose Wi-Fi if you need real-time status updates or remote locking. Pick offline models for basic code access without internet reliance. Consider your router’s signal strength at the door location to ensure stable connections for Wi-Fi devices.

Look for

• Built-in Wi-Fi module
• No separate hub required
• 2.4GHz network support

Access methods

Locks offer various entry options, including keypads, fingerprints, mobile apps, and physical keys. The eufy C220 combines Wi-Fi with fingerprint scanning for quick entry. The Chamberlain myQ adds video doorbell integration for visual verification before unlocking. Some models, like the Aqara U400, use Ultra-Wideband (UWB) for hands-free proximity entry with compatible phones. Keypad-only options provide reliable code access without biometric sensors. Select a method that matches your daily routine. Fingerprint sensors offer speed, while keypads ensure access without a phone. Verify the number of supported methods for flexibility.

Look for

• Fingerprint sensor capacity
• Keypad button durability
• App-based remote entry

Smart home compatibility

Integration with voice assistants and automation platforms expands lock utility. The Schlage Encode supports voice commands for hands-free operation. The Aqara U400 is optimized for Apple users, leveraging UWB for seamless proximity unlocking. Most Wi-Fi locks work with major ecosystems via their respective apps. Check if the lock supports your existing smart home setup before purchasing. Compatibility ensures you can automate routines, such as locking the door when you leave. Lack of support may limit functionality to basic app control. Verify platform support in the product specifications.

Look for

• Alexa or Google support
• Apple HomeKit compatibility
• Matter protocol support

Physical dimensions

Lock dimensions determine fit for your door’s bore hole and backset. The Schlage Encode measures 3 inches wide by 5 inches high. The TEEHO keypad is slightly narrower at 2.95 inches wide. Ensure the lock fits your door’s existing hardware or plan for drilling adjustments. Larger units may accommodate more batteries or sensors. Compact designs suit narrower door frames. Measure your door’s edge bore and face bore before buying. Mismatched dimensions can prevent installation or require professional modification. Check width, height, and thickness specs carefully.

Look for

• 2-1/8 inch bore hole fit
• Standard backset compatibility
• Door thickness range

Build quality and rating

Durability depends on materials and security ratings. The eufy C220 carries a BHMA Grade 3 rating, indicating high resistance to forced entry. Look for solid metal construction and weather-resistant finishes like satin nickel or matte black. The Chamberlain myQ includes a 2K HDR camera, adding visual security. IP53 ratings, like on the eufy, protect against light dust and water spray. Higher ratings offer better long-term reliability in harsh weather. Cheaper plastic components may degrade faster. Prioritize locks with recognized security certifications for peace of mind.

Look for

• BHMA Grade 1 or 3
• IP53 or higher rating
• Solid metal construction

Power source

Most smart locks use batteries, typically AA or lithium cells. Wi-Fi models consume more power than Bluetooth or keypad-only locks. The Philips 4200 Series and Schlage Encode rely on battery packs. Check battery life estimates in the specifications. Some locks offer low-battery alerts via app or audible chimes. Consider locks with USB charging ports for emergency power. Battery replacement frequency impacts convenience. High-traffic doors may drain batteries faster. Ensure you can easily access the battery compartment for swaps.

Look for

• Battery type and count
• Estimated battery life months
• Low-battery alert system

Types of Smart Locks and Doorbells

Wi-Fi Deadbolts

These locks connect directly to your home network without a separate hub. The Schlage Encode uses Wi-Fi for remote monitoring and voice assistant support. You get high-capacity code storage and built-in alarms. This setup simplifies installation but requires a stable 2.4GHz connection. It suits users who want hub-free control and multi-user access from any location.

Keypad Deadbolts

Keypad models rely on code entry for access. The TEEHO and Kwikset Powerbolt 250 offer straightforward, code-based security. They often include auto-locking features and fit standard bore holes. Some, like the Kwikset, manage codes locally without an app. This type is ideal for those who prefer physical security and reliable hardware over digital connectivity or remote features.

Biometric Smart Locks

Biometric locks use fingerprint sensors for quick entry. The eufy Security C220 offers direct Wi-Fi access with fingerprint unlocking. It features a BHMA Grade 3 build and an IP53 weather rating. The Aqara U400 adds UWB technology for hands-free entry with Apple devices. These locks suit users wanting fast, keyless access while maintaining robust physical security standards.

Video Doorbell Locks

These units combine a deadbolt with a video camera. The Chamberlain myQ 3-in-1 includes a 2K HDR camera and color night vision. It provides hands-free facial recognition alongside four other entry methods. This all-in-one design gives you comprehensive front-door oversight. It is best for users who want security and visual monitoring in a single frame without separate devices.

Integrated Handle Locks

Some locks replace the entire exterior hardware, including the handle. The Philips 4200 Series Wi-Fi Deadbolt with Handle offers integrated hardware. It provides fast biometric unlocking and direct network connectivity. This type is suitable for full front door replacements. You get remote access and customizable code scheduling without needing to install separate components on your door.

Common Mistakes When Buying Smart Locks

Assuming all smart locks fit your door

Ignoring the backset measurement can prevent installation. Measure the distance from the edge of the door to the center of the hole. Standard sizes are 2-3/8 inches or 2-3/4 inches. Mismatched dimensions require drilling new holes or buying an adapter plate.

Overlooking the need for remote access

Bluetooth-only locks require your phone to be nearby to operate. They lack remote access capabilities. Choose a model with Wi-Fi or a separate hub if you need to lock or unlock the door from a distance. This ensures convenience when you are away from home.

Underestimating battery maintenance requirements

Battery life varies significantly between models. Some last months, while others require frequent changes. Check the battery type and estimated duration in the specs. Plan for replacements or select models with low-battery alerts to avoid being locked out unexpectedly during travel or emergencies.

Forgetting to check for physical key backup

Physical keys provide a critical backup when electronic systems fail. Ensure the lock includes a traditional key override. This feature allows entry during power outages or technical glitches. Do not rely solely on digital codes or smartphone apps for essential home access.

Not verifying door thickness compatibility

Door thickness affects compatibility. Most locks fit doors between one and three inches thick. Verify your door’s exact measurement before purchasing. If your door is unusually thick or thin, standard models may not mount correctly. This prevents hardware damage and installation failures.
