SMART LOCK BUYER’S GUIDE: WHAT TO KNOW BEFORE YOU INSTALL ONE

Smart locks offer incredible convenience, but not all models are created equal. Here is a locksmith’s perspective on which features are essential for security and which ones you can safely skip.

THE REAL BENEFITS OF SMART LOCKS

Smart locks are most effective when managing access for multiple people, such as family members, guests, contractors, or cleaning services.

Access Control: Time-limited PIN codes and remote unlocking eliminate the need to constantly cut and distribute physical keys.
Tracking: You can monitor who enters and leaves your property in real-time.

FEATURES THAT MATTER

When choosing a smart lock, prioritize these core features over marketing buzzwords:

Physical Key Backup: Essential for gaining entry if the batteries die or the electronics fail.
Auto-Lock Timer: An adjustable timer that ensures your door is always secured behind you.
ANSI Grade 2 Certification: This ensures a minimum level of structural security and durability.
Local Control: Systems that don't rely entirely on the cloud are more reliable.
Encryption: Look for secure protocols like Z-Wave Plus, Zigbee 3.0, or Matter.
Battery Alerts: Visible or audible low-battery warnings to prevent lockouts.

FEATURES YOU CAN SKIP

When choosing a smart lock, prioritize these core features over marketing buzzwords:

Built-in Cameras: A dedicated doorbell camera usually offers better video quality and flexibility.
Voice Assistants: Often present a security risk and offer limited practical utility.
Geofencing Auto-Unlock: Can lead to "false unlocks," where the door opens while you are still far away or already inside.
Subscription Models: Avoid locks that require monthly fees to access basic security features.

INSTALLATION CONSIDERATIONS

While most smart locks fit standard door preparations, older or warped doors may require professional adjustment. Proper alignment is critical; improper installation is the leading cause of premature motor failure in smart locks. If you are unsure, professional installation ensures the lock operates smoothly and securely.
