What does the August Wi-Fi Smart Lock (4th Generation) do?

The August Wi-Fi Smart Lock (4th Generation) adds app-controlled access to a compatible deadbolt while keeping the exterior key cylinder in place. The motorized unit mounts on the inside of the door and turns the existing lock, so household members can still use a physical key from outside.

Built-in Wi-Fi connects the lock to remote app controls, while Bluetooth supports nearby phone communication. The app provides lock status and access management, including ways to share access with guests. DoorSense, the included door sensor, helps distinguish a shut door from a door that is still open, giving the lock status information beyond whether the bolt is extended.

The retrofit design is the central reason to consider this model. Shoppers who want a keypad or a different exterior appearance should verify whether an accessory or another lock style fits their needs. The August Wi-Fi Smart Lock (4th Generation) focuses on adding smart functions to existing hardware rather than replacing the full deadbolt.

Will the August Wi-Fi Smart Lock (4th Generation) fit my door?

The August Wi-Fi Smart Lock (4th Generation) is designed for compatible single-cylinder deadbolts and installs on the interior side of the door. Compatibility is not universal, so check the manufacturer’s fit guidance against your deadbolt, thumb-turn, door thickness, and available interior clearance before ordering.

A retrofit lock needs a compatible existing deadbolt assembly to turn smoothly. Look closely at the shape and movement of the interior thumb-turn, and confirm the door closes and latches cleanly. Door alignment problems can affect a smart lock just as they affect a standard deadbolt, so resolve sticking or loose hardware before installation.

The August Wi-Fi Smart Lock (4th Generation) does not replace the exterior key cylinder. That can be useful for households that want to retain current keys or preserve a familiar outside appearance. If your door uses a mortise lock, interconnected lock, or another nonstandard setup, verify fit before purchase rather than assuming the retrofit design will work.

Does the August Wi-Fi Smart Lock (4th Generation) need a Wi-Fi bridge?

The August Wi-Fi Smart Lock (4th Generation) has built-in Wi-Fi, so it does not require a separate August Wi-Fi bridge for remote app access. The lock also has Bluetooth for communication with a nearby phone, giving the August Wi-Fi Smart Lock (4th Generation) two wireless connection types.

Remote controls depend on a working home network, account setup, and the lock remaining connected. Check the product’s current network requirements and make sure the signal reaches the door where the lock will be installed. A router with strong coverage in the living room can still leave a weak signal at an exterior entrance.

Smart-home compatibility and features can vary by platform, app version, and account configuration. Before buying, verify the specific voice assistant or ecosystem you use and review the latest compatibility details for the August Wi-Fi Smart Lock (4th Generation). Confirming that information helps avoid relying on an integration that does not match your setup.

How does DoorSense work on the August Wi-Fi Smart Lock (4th Generation)?

DoorSense on the August Wi-Fi Smart Lock (4th Generation) uses a separate sensor to report whether the door is open or closed. That status complements the lock’s bolt information, since a retracted bolt does not by itself tell you whether the door is sitting open.

The sensor needs to be positioned according to the installation instructions, and the door must align consistently for status reporting to be useful. Take time during setup to calibrate the lock and sensor, then check the app’s status after opening and closing the door. Correct alignment helps the August Wi-Fi Smart Lock (4th Generation) give clearer updates.

DoorSense is especially useful for households that want a quick check before leaving or before locking remotely. Treat any app status as a helpful indicator, not a substitute for confirming that the door and frame are properly installed. If your door shifts or does not close firmly, address that issue before depending on automated locking.

What batteries does the August Wi-Fi Smart Lock (4th Generation) use?

The August Wi-Fi Smart Lock (4th Generation) uses 2 CR123 batteries, which shoppers should factor into upkeep and installation planning. The exact battery life varies with usage, connectivity, door alignment, and other conditions, so avoid treating a single owner estimate as a guarantee.

Check the battery status in the app and keep suitable replacement batteries available. Frequent locking activity or a door that puts extra resistance on the bolt can increase power use. A properly aligned deadbolt helps the August Wi-Fi Smart Lock (4th Generation) turn without unnecessary strain and supports smoother daily operation.

The battery compartment is on the interior unit, keeping routine battery changes inside the home. Before purchasing, confirm the exact battery type in the current product documentation and listing. During Black Friday 2026, compare whether a bundle includes batteries or accessories, and check that any included items match the model in the cart.

What should I check in August smart lock Black Friday deals?

For Black Friday 2026, compare the August Wi-Fi Smart Lock (4th Generation) listings by model, included accessories, finish, seller, and return policy. Product pages can look similar while offering different bundles, so verify that the listing names the 4th Generation model and includes the DoorSense sensor if that feature matters to you.

Check the seller and fulfillment details, delivery window, stock status, and return conditions before checkout. Look at the full listing rather than relying only on a search-result headline or a small product image. A discounted bundle is useful only when the included components suit your installation and the product is eligible for the retailer’s stated return terms.

The best bet is to settle compatibility first, then compare listings for the exact August Wi-Fi Smart Lock (4th Generation). Review finish availability and accessory contents as stock changes, and save the product page so you can revisit the same configuration. That approach makes deal comparisons clearer without sacrificing fit or support.
