What makes the August Wi-Fi Smart Lock (4th Generation) a Black Friday 2026 deal to watch?
The August Wi-Fi Smart Lock (4th Generation) combines 2.4 GHz Wi-Fi, Bluetooth, and DoorSense in a retrofit lock aimed at compatible single-cylinder deadbolts. Shoppers considering it for Black Friday 2026 should compare the complete listing rather than looking only for a seasonal label. A useful offer is one that matches the exact generation, includes the accessories you need, and comes from a seller with clear return terms.
Compare color choices, availability, included mounting parts, and any keypad bundle against the standard lock listing. Bundles are relevant for households that want keypad entry, because the August Wi-Fi Smart Lock (4th Generation) does not have an exterior number pad built in. Review seller identity and stock before checkout, then confirm that the return window gives you time to check your door’s fit.
Will the August Wi-Fi Smart Lock (4th Generation) fit my door?
The August Wi-Fi Smart Lock (4th Generation) is designed to fit many 1-cylinder deadbolt setups from the inside while leaving compatible exterior hardware in place. The retrofit format is convenient for renters or homeowners who want to keep their existing key, but door and lock configurations vary. Check the manufacturer’s compatibility information against your deadbolt before selecting a Black Friday listing.
Pay attention to whether your deadbolt is single-cylinder and whether the interior thumb turn and surrounding trim leave enough room for installation. A product photo alone cannot confirm fit. If the door has unusual trim, a multipoint locking system, or a nonstandard deadbolt, verify the details with August’s compatibility resources or the retailer before ordering. Keep the original interior parts until installation is confirmed.
What smart-home features does the August Wi-Fi Smart Lock (4th Generation) include?
The August Wi-Fi Smart Lock (4th Generation) supports Amazon Alexa, Google Assistant, and Apple HomeKit, with built-in 2.4 GHz Wi-Fi for remote app access. Bluetooth provides a nearby wireless connection, and DoorSense reports whether the door is open or closed. Those features suit households that want to check lock status or manage access from a phone without replacing the exterior lock.
Smart-home behavior depends on your accounts, network, app settings, and chosen platform. Review the current setup requirements for the ecosystem you use, and confirm that the functions you care about—such as voice control or remote status—are supported in your configuration. The August Wi-Fi Smart Lock (4th Generation) focuses on app-based control; keypad codes require a separate accessory.
How does installation work for the August Wi-Fi Smart Lock (4th Generation)?
The August Wi-Fi Smart Lock (4th Generation) attaches to the inside of a compatible deadbolt, so installation retains the outside cylinder and key. The retrofit design avoids replacing the entire deadbolt assembly, but correct fit and alignment still matter. Follow the included instructions and app prompts, and check the product’s compatibility guidance before opening a Black Friday purchase.
Allow time to remove the existing interior thumb-turn hardware, fit the mounting plate, attach the lock, and complete setup in the app. DoorSense also needs to be positioned according to its instructions for reliable door-status reporting. Keep the packaging and existing parts until you confirm the lock operates smoothly by hand and through the app. Do not force a lock that binds during setup.
What batteries does the August Wi-Fi Smart Lock (4th Generation) use?
The August Wi-Fi Smart Lock (4th Generation) uses 2 CR123 batteries, so shoppers should check battery availability and the manufacturer’s current battery guidance before purchase. Battery life varies with usage, door alignment, network conditions, and other factors; avoid treating any estimate as a guarantee. The app provides lock-related status information to help owners keep an eye on upkeep.
Add replacement batteries to your ownership checklist and follow August’s instructions for battery changes. A door that is difficult to turn can add strain to a smart lock, so smooth deadbolt operation matters for everyday use as well as battery management. If a Black Friday bundle includes extra accessories, confirm that batteries are actually listed in the box rather than assuming they are included.
Does the August Wi-Fi Smart Lock (4th Generation) include a keypad?
The August Wi-Fi Smart Lock (4th Generation) does not include built-in exterior number keys; shoppers who want keypad entry need a separate August keypad accessory or a bundle that explicitly lists one. The main lock preserves the existing exterior hardware, which is useful for keeping a physical key, but keypad access is a separate buying decision.
For Black Friday 2026, read the box contents carefully and distinguish a lock-only package from a keypad bundle. Confirm the keypad model is compatible with the August Wi-Fi Smart Lock (4th Generation), and check whether the listing includes mounting supplies or batteries for the accessory. If app access and an existing key are enough, a keypad is optional rather than a requirement.
Buying Guide
Verify deadbolt compatibility first
Check that your door uses a compatible single-cylinder deadbolt and that the interior area allows the August Wi-Fi Smart Lock (4th Generation) to fit. Compare your existing hardware with the manufacturer’s compatibility guidance before placing an order.
Compare what each listing includes
Review whether the Black Friday 2026 listing contains only the lock or adds a keypad or other accessory. Check the exact generation, color, seller, and package contents; bundle names do not always describe every included item.
Check network and ecosystem needs
The August Wi-Fi Smart Lock (4th Generation) uses 2.4 GHz Wi-Fi and supports Alexa, Google Assistant, and Apple HomeKit. Confirm your home network and preferred platform meet the current setup requirements before buying.
Read return and support terms
A clear return window is valuable if your deadbolt fit is uncertain. Check the seller’s return terms, warranty information, and support options, and keep the packaging until the August Wi-Fi Smart Lock (4th Generation) is installed and working as expected.
Alternatives to Consider
