August Smart Lock (5th gen)
New #1 Aug 2026 · the renter's dreamThe August replaces nothing — it clamps over the inside of your existing deadbolt, so the outside of the door never changes and your keys keep working. Twelve minutes after opening the box, ours was auto-unlocking as we reached the handle: 0.9 seconds from approach to open, the fastest we've ever timed, and 97 of 100 auto-unlock approaches worked on the first try. The tax is the battery — three months measured, and you will learn the low-battery chirp.
Pros
- Fastest unlock we've timed (0.9s)
- 12-minute install, keys keep working
- Landlord-proof — nothing visible outside
Cons
- 3-month battery life is the tax
- Inside-only — keypad costs extra
