August vs Yale Smart Locks 2026: Which Smart Lock Should You Buy?

Smart locks have matured into one of the most practical alexa-2026" title="Apple HomeKit vs Google Home vs Alexa: Best Smart Home Ecosystem 2026" class="internal-link">smart home upgrades you can make — and in 2026, the market is dominated by two brands with fundamentally different philosophies: August and Yale. Choosing between them is essentially choosing between two very different visions of how a smart lock should work.

August pioneered the retrofit smart lock concept: install it over your existing deadbolt in minutes without touching your exterior hardware. You keep your keys, you keep your existing lock, and you gain a smart interior component that adds auto-lock, auto-unlock, and remote access. Yale, which is now a sister brand to August under the ASSA ABLOY umbrella, takes the full-replacement approach — the Yale Assure Lock 2 replaces your entire deadbolt with a sleek, keypad-integrated unit that eliminates the need for physical keys entirely.

Both approaches have real merit. August suits renters who cannot change exterior hardware, or homeowners who love their existing deadbolt finish and do not want to replace it. Yale suits homeowners who want a clean, keypad-first look and are willing to do a slightly more involved installation for a more polished result. Here is how they compare in 2026.

August Smart Locks

August Wi-Fi Smart Lock (4th Gen) — $229.99

The August Wi-Fi Smart Lock is the flagship August product and the smartest retrofit lock available. Installation takes under ten minutes: remove your existing interior thumb-turn, attach the August mounting plate, snap the August lock onto your existing deadbolt cam. No exterior hardware changes, no rekeying, no drilling. When you are done, your door looks identical from the outside.

The Wi-Fi model has built-in 2.4 GHz Wi-Fi — no bridge or hub required — and connects directly to the August app for remote lock/unlock from anywhere. DoorSense is one of August's most useful features: a small magnetic sensor on the door frame tells the app whether your door is physically open or closed. August will alert you if you lock the lock but the door is ajar — a common scenario that a lock-only state indicator misses entirely.

Auto-unlock uses your phone's geofencing: when you arrive home (detected by your phone's GPS leaving and re-entering a defined radius), August automatically unlocks the door so your hands are free for groceries or a child. Auto-lock triggers after a set delay once the door closes — you can set it to lock 30 seconds, 1 minute, or up to 30 minutes after closing.

Pros:

• 10-minute installation — no exterior changes, no rekeying
• Keeps your existing deadbolt (and its key)
• Built-in Wi-Fi — no hub required
• DoorSense door position detection prevents false "locked" status
• Works with Alexa, Google Assistant, HomeKit, and SmartThings
• Auto-unlock is the best implementation in its class
• Renters can install and uninstall without affecting lease compliance

Cons:

• Interior-only design is not as aesthetically cohesive as Yale's full replacement
• No built-in keypad (requires the August Smart Keypad add-on, $79.99, sold separately)
• Battery life is shorter (~3 months) than Yale's 12-month runtime
• Limited exterior finish options — August lives inside, so only interior color matters

August Smart Lock + Connect (Bundle) — $249.99

The August Smart Lock with Connect bundle pairs the retrofit lock with August's Wi-Fi bridge for older homes with 2.4 GHz network compatibility concerns. For most modern routers and homes built after 2010, the standalone Wi-Fi model is sufficient. The bundle is aimed at users who want a wired bridge for more reliable connectivity — useful in thick-walled homes where the lock sits far from the router.

Pros:

• More stable connectivity in challenging Wi-Fi environments
• Bridge plugs into a standard outlet and creates a dedicated Bluetooth-to-Wi-Fi bridge

Cons:

• Requires an outlet near the door
• The standalone Wi-Fi model handles most homes without the extra hardware

August Smart Keypad — $79.99

The August Smart Keypad is an optional add-on that mounts outside your door and connects wirelessly to the August lock inside. It generates codes via the August app — you assign codes for family members, guests, or service providers, set expiration dates, and revoke access remotely. Each code press is logged with a timestamp in the August app's activity feed.

This is how August achieves what Yale builds in natively: keypad access without a key. The trade-off is that you are paying extra for what Yale includes in the base product, and the keypad is a separate wireless device that needs its own batteries.

Pros:

• Codes are managed entirely in the August app with granular scheduling
• Visitors can enter without a phone or physical key
• Easy to install — adheres to exterior surface, no wiring

Cons:

• Additional cost on top of the lock itself
• Another device to keep battery in
• Separate wireless unit means potential connectivity gap between keypad and lock

Yale Smart Locks

Yale Assure Lock 2 — $249.99

The Yale Assure Lock 2 is the definitive full-replacement smart lock for homeowners who want a complete, integrated solution. Installation replaces your entire deadbolt — interior and exterior hardware — with a single cohesive unit. The exterior features a backlit keypad built directly into the lock body, so there is no separate keypad to install or battery to maintain. The interior is a clean thumb-turn design with no visible lock cylinder, giving a more modern aesthetic than traditional deadbolts.

The Assure Lock 2 comes in four finish options — Satin Nickel, Oil-Rubbed Bronze, Matte Black, and Polished Brass — so it can match your existing door hardware on both sides. This is Yale's key aesthetic advantage: August only changes the inside.

Battery life is exceptional at approximately 12 months on four AA batteries — four times longer than August's 3-month runtime, a meaningful practical advantage. The lock has built-in Wi-Fi on the Wi-Fi model and integrates natively with Alexa, Google Assistant, and Apple HomeKit. Yale's DoorSense feature matches August's, detecting whether the door is physically open before confirming a locked state.

Pros:

• Replaces entire deadbolt — cohesive look inside and out
• Built-in backlit keypad, no add-on required
• 4 exterior finish options match existing door hardware
• 12-month battery life is class-leading
• Works with Alexa, Google Assistant, HomeKit, and SmartThings
• Z-Wave model available for SmartThings and other Z-Wave hubs
• Full key cylinder included for backup physical key access

Cons:

• Full deadbolt replacement requires more installation effort (15-30 min)
• Cannot use your existing deadbolt
• Not suitable for renters who cannot modify exterior hardware
• Exterior cylinder is visible — some prefer the keypad-only aesthetic of competitors

Yale Assure Lock 2 with Keypad (Touch) — $279.99

The Yale Assure Lock 2 Touch upgrades the standard backlit keypad to a capacitive touchscreen — no individual buttons, just a smooth glass-like surface that illuminates when you approach. It supports fingerprint-style touch codes (tap a sequence on specific zones rather than entering a numeric PIN), which can be faster for regular users.

The Touch model is otherwise identical to the standard Assure Lock 2 in specs and compatibility. It is a style upgrade primarily, though the touchscreen is also easier to clean and harder to determine which buttons are being used most frequently (a subtle security benefit that prevents code-guessing from worn key surfaces).

Pros:

• Sleek touchscreen interface is more attractive than button keypads
• Zone-tap codes add a layer of code security
• Easy-clean smooth surface

Cons:

• $30 premium over standard model for primarily aesthetic upgrade
• Touchscreen can be less reliable in heavy rain or with wet hands

Yale Approach Lock with Wi-Fi — $199.99

Yale's Approach Lock is the brand's most affordable Wi-Fi smart lock and a great entry point for users who do not need a full keypad. It features a push-button interior design without an exterior keypad — the locking mechanism is controlled entirely via the Yale app or voice assistants. It is ideal for a secondary door (back door, garage entrance) rather than a primary front door entry.

Auto-lock and auto-unlock are supported, and it integrates with the same Yale app ecosystem as the Assure Lock 2, allowing unified management of multiple locks across one property.

Pros:

• Most affordable Yale Wi-Fi smart lock
• Full Yale app and voice assistant integration
• Good for secondary doors where keypad access is less critical

Cons:

• No exterior keypad — codes only accessible via app or voice
• Full deadbolt replacement required
• Less suitable as primary front door lock without a separate keypad

Head-to-Head: Where August Wins

Renter-Friendly Installation

August's retrofit design is unambiguous winner for renters or anyone in a home where exterior hardware cannot be changed. You install it yourself in ten minutes, keep your existing deadbolt and key, and remove it just as quickly when you move out — leaving zero trace. No landlord conversation required, no lease concerns, no exterior modification.

Auto-Unlock Experience

August's auto-unlock is widely regarded as the smoothest implementation in the industry. The geofencing algorithm is well-tuned to avoid false unlocks while being responsive enough to have the door unlocked before you reach it. Yale offers the same feature, but August has spent more years refining the geofencing radius and approach detection, and it shows in day-to-day reliability.

Smart Home Ecosystem Compatibility

August works with Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, and even Ring Alarm (if you use August with a Ring system, door lock events appear in Ring's activity feed). The breadth of integrations is slightly broader than Yale's comparable models, and August has been a first-adopter of new integration standards throughout its history.

Head-to-Head: Where Yale Wins

Aesthetic Integration

Yale's full deadbolt replacement creates a cohesive interior/exterior look that August simply cannot achieve. When you choose Matte Black for your Yale Assure Lock 2, both the exterior keypad and the interior turn are Matte Black, matching your door hardware exactly. August changes only the interior component, leaving whatever finish your existing deadbolt has on the outside unchanged.

For homeowners who care about door aesthetics — and many do — Yale's approach is the more intentional design choice.

Built-in Keypad

Yale includes the keypad in the base product. August charges $79.99 extra for the Smart Keypad add-on. For any household that wants code-based entry (visitors, cleaners, family members without smartphones), Yale is the better value proposition by a significant margin.

Battery Life

Yale's 12-month battery life versus August's 3-month runtime is a practical quality-of-life advantage. Replacing August's batteries four times a year is not a burden, but it is a chore that Yale users simply do not face.

Which Should You Buy?

Buy August Wi-Fi Smart Lock if you:

• Rent your home and cannot modify exterior hardware
• Love your existing deadbolt and want to keep it
• Want the fastest, least invasive installation
• Already use the August app from a previous lock
• Plan to take the lock with you when you move

Buy Yale Assure Lock 2 if you:

• Own your home and want a permanent, polished installation
• Want a built-in keypad without paying extra
• Need multiple exterior finish options to match door hardware
• Want the longest battery life in its class
• Prefer a single cohesive deadbolt unit over a retrofit adapter

For vacation rentals and Airbnb: Yale Assure Lock 2 — the built-in keypad and code management make it ideal for guest turnover without needing to distribute physical keys.

For apartments and condos: August Wi-Fi Smart Lock — install it in minutes, no exterior changes, works with your existing key for the property manager.

Our Pick

For homeowners, Yale Assure Lock 2 is the better product in 2026. The built-in keypad, four finish options, 12-month battery life, and cohesive full-replacement design make it the more complete smart lock at a comparable price. You do not need to buy add-ons to achieve the full feature set.

For renters and retrofit-friendly installers, August Wi-Fi Smart Lock remains the category-defining product. No other lock matches its 10-minute installation, renter-friendly design, and polished auto-unlock experience. Both brands are owned by ASSA ABLOY and share the same underlying quality standards — the differences are entirely about installation philosophy and use case.
