August
August Wi-Fi Smart Lock
A smart lock that installs entirely on the inside of your door, over your existing deadbolt, so your landlord never knows it's there
$180
What we like
- Installs entirely on the interior side of your door over your existing deadbolt, no exterior changes visible to your landlord
- Built-in Wi-Fi (no separate hub or bridge required, unlike older August models)
- DoorSense tells you whether the door is actually closed and latched, not just locked
- Auto-Lock and Auto-Unlock use geofencing so the door locks behind you and unlocks when you get home
What could be better
- Only works with standard single-cylinder deadbolts, so check your door hardware before buying
- Battery life is about 3 months on 4 AA batteries, and a dead battery can lock you out if you don't watch the app alerts
- No physical keypad included (sold separately), so guests need the app or a separate accessory
Best for
- • Renters who want a smart lock without changing any exterior hardware
- • People who frequently have guests, dog walkers, or cleaners who need temporary access
- • Anyone who's left the house and wondered 'did I lock the door?' (DoorSense answers that)
Our verdict
The August Wi-Fi Smart Lock is the best smart lock for renters, full stop. It installs on the inside of your door in about 10 minutes, your existing keys still work from the outside, and your landlord has no idea it's there. The built-in Wi-Fi (no bridge needed) and auto-lock/unlock make daily use genuinely hands-free. The 3-month battery life is the main annoyance: keep an eye on the app for low-battery warnings or you'll be locked out fumbling for keys. When you move, unscrew it and your door is back to normal.
