Buying Guide: Key Considerations For Thick-Door Smart Locks
- Door thickness compatibility: Check the lock’s stated thickness range (some models support 40–90 mm or similar). Thicker doors may need longer bolts or specific backsets to ensure secure fit.
- WiFi and hub requirements: Decide between built-in WiFi and hub-dependent systems. Built-in WiFi enables remote access without additional hardware, while hubs can expand compatibility with other smart devices.
- Unlock methods: Consider fingerprints, codes, mechanical keys, mobile apps, and voice control. Environments with children or visitors benefit from multiple options for easy access.
- Power and battery life: Evaluate battery type and life expectancy. Longer battery life reduces maintenance, especially on exterior doors where frequent battery changes are inconvenient.
- Security features: Look for tamper alerts, access history, auto-lock timers, and remote notifications. A transparent activity log helps monitor who enters and when.
- Smart home integration: If you use Alexa, Google Assistant, or Apple HomeKit, verify compatibility. Some locks offer native voice control while others require bridges or hubs.
- Installation effort: Some locks replace a standard deadbolt or handle, while others require additional hardware for thick doors. Review mounting depth and backset specs before purchase.
