August Wi Fi Smart Lock
What works
Retrofit design — keeps existing keys and exterior hardware intact
10-minute installation with no door modification
Native Apple HomeKit integration
What doesn't
No exterior keypad — guests need the app or a physical key
Motor can drain AA batteries faster than Yale in high-traffic homes
Relies on existing deadbolt quality for physical security
Yale Assure Lock 2
What works
Keypad allows PIN code access — no phone, no key required
Full deadbolt replacement with controlled physical security
Multiple access codes with individual schedules for guests
What doesn't
Requires full deadbolt replacement — not suitable for renters
More complex installation — 20-30 min, exterior modification required
$259.99 is expensive vs. August's retrofit approach
Bottom line
Our pick: Yale Assure Lock 2. It edges out the alternative on keypad allows pin code access — no phone, no key required. That said, August Wi Fi Smart Lock still wins on retrofit design — keeps existing keys and exterior hardware intact — consider it if that single trade matters most for your use.
