Smart Lock Buying Guide: What to Look For

Choosing the right smart lock depends on your specific needs. Use this buying guide to narrow down your options.

1. Connectivity: Wi-Fi vs. Bluetooth vs. Z-Wave

• Wi-Fi: Best for direct remote access without a hub. Drains battery faster.
• Bluetooth: Good for close-range use. Requires a hub or bridge for remote access.
• Z-Wave/Thread: Ideal for smart home hubs (Samsung SmartThings, Hubitat). Low power usage.

2. Key Override

Always choose a lock with a physical key backup. Batteries can die, and electronics can fail. A traditional key ensures you're never locked out.

3. Auto-Lock and Auto-Unlock

Auto-lock automatically locks the door after a set time. Auto-unlock uses geofencing to unlock when you approach. These features add convenience but can be a security risk if not configured properly.

4. Voice Assistant Compatibility

If you use Alexa, Google Assistant, or Siri, ensure the lock is compatible. Most modern locks support at least one ecosystem.

5. Battery Life and Alerts

Most smart locks run on 4 AA batteries that last 6–12 months. Look for locks that send low-battery alerts to your phone. Some models (like the Schlage Encode Plus) have a 9V battery backup on the exterior.

6. Installation Difficulty

Most smart locks are designed for DIY installation. You'll need a screwdriver and about 20 minutes. However, older doors or non-standard deadbolts may require a locksmith.
