August makes retrofit smart locks that attach to the inside of your existing deadbolt, so you get keyless entry while keeping your original keys and door hardware.
The August Wi-Fi Smart Lock is the renter-friendly way to make a door smart: it installs over the deadbolt you already have in about ten minutes, leaving the exterior lock — and your landlord’s key — untouched. From the August app you can lock and unlock remotely, hand out virtual guest keys, check whether the door is actually closed with DoorSense, and see a full activity log. August is part of the ASSA ABLOY group alongside Yale, and its locks integrate with most major smart home platforms.
Because the lock reuses your existing cylinder, the door looks completely ordinary from outside — a real plus for condos and rentals with strict rules about changing hardware. The included DoorSense sensor is a small but important difference from rivals: many smart locks report only the bolt position, while August can tell you whether the door itself is actually shut, not just locked.
The August Wi-Fi Smart Lock sells for $229.99 as a one-time purchase with no subscription needed for app control and remote access. The optional wireless Smart Keypad costs about $79.99. Older Pro models and bundles are frequently discounted.
Renters and anyone who wants smart locking without replacing door hardware — plus hosts and families who need to share temporary access without copying physical keys.
