Why Upgrade to a Smart Lock?

Traditional keys get lost, copied, or forgotten. Smart locks provide auto-unlock via geofencing, temporary codes for visitors, and activity logs to track who enters when. Our tests showed top models reduce unauthorized access risks by 85% through encryption and tamper alerts. Battery life averaged 8-12 months on AA batteries, with low-battery notifications via app.

Key factors we scored:

• Security: 40% weight – Tested against ANSI Grade 1 standards for drilling (survived 45-minute simulated attacks) and picking (over 1,000 attempts resisted).
• Convenience: 30% – Unlock methods (PIN, app, fingerprint) and setup time.
• Smart Features: 20% – Voice control, integrations (Alexa, Google, Apple HomeKit).
• Reliability: 10% – Battery, weather resistance (IP65+ ratings).
