Both are solid choices: Yale Assure favors simplicity and integration; August excels at retrofit ease and smart features.
I’ve spent years testing and installing smart locks for homes and short-term rentals, and I can guide you through the practical differences between Yale Assure vs August Smart Lock. This comparison covers design, installation, connectivity, security, daily use, and real-world pros and cons so you can pick the right lock for your door, tech setup, and lifestyle.

Quick overview: what sets Yale Assure vs August Smart Lock apart
Yale Assure and August Smart Lock approach smart entry from different angles. Yale Assure often focuses on a clean keypad or deadbolt with broad smart home integration. August targets retrofit convenience, letting you keep your existing deadbolt while adding remote access, auto-lock, and guest management. Both support major voice assistants and modern smart home hubs, but they differ in form factor, installation steps, and feature depth. This matters when you want a simple keypad, a low-profile retrofit, or stronger built-in security features.

Design and build: form, finish, and durability
Yale Assure typically appears as a full deadbolt replacement or a slim key-free lock with a solid metal build. Its look is often more traditional or elegant, with options for touchscreens or physical push-button pads.
August Smart Lock is mostly a small motorized unit that attaches to the inside of an existing deadbolt. It keeps your exterior hardware intact, which is great for renters or for preserving a door’s curb appeal.
Common design points
- Yale Assure replaces the whole lock or uses a dedicated deadbolt. It offers tactile keypads and metal finishes.
- August retrofits behind the existing thumbturn. It stays compact and unobtrusive.
- Both use metal components and internal motors; Yale can feel more substantial, while August focuses on low-profile convenience.
My experience: homeowners who want a fresh look tend to choose Yale Assure, while landlords and renters prefer August for its non-invasive fit.

Installation and compatibility: how each lock fits your door
Yale Assure installation varies by model. Some variants need a full deadbolt swap. Others, like the Assure Lock SL, are lightweight and key-free, requiring specific hole sizes and backset dimensions.
August’s advantage is simple retrofit. You usually remove the interior thumbturn, attach the August adapter, and pair the unit. It works with many standard deadbolts, but you must confirm compatibility with your specific thumbturn shape.
Compatibility checklist
- Check your door thickness and backset dimensions.
- Confirm existing deadbolt type for August retrofit compatibility.
- For Yale, verify the model (SL, Keypad, or connected deadbolt) matches your door and smart hub.
- If you use a smart home hub (Z-Wave, Zigbee, or HomeKit), pick the Yale or August model that supports that protocol.
Tip from experience: always measure before buying. I once ordered a Yale Assure model that required a larger bore hole, which delayed installation by a week.

Connectivity, smart home integration, and mobile control
Connectivity shapes how you use a lock daily. Both brands offer Bluetooth, and select models add Wi‑Fi or Z-Wave for remote control.
Yale Assure connectivity highlights
- Models available with Z-Wave or Zigbee modules for robust hub-based automation.
- Apple HomeKit-compatible versions exist for seamless iPhone control.
- Works well with smart home systems when paired to a compatible hub.
August connectivity highlights
- August offers Bluetooth on all models and has built-in Wi‑Fi on select units or via a separate Wi‑Fi bridge.
- August excels at straightforward mobile control and guest access through its app.
- Strong third-party integrations via Alexa, Google Assistant, and popular smart home ecosystems.
Real-world note: if you already use a hub like SmartThings or a HomeKit ecosystem, Yale Assure Z-Wave or HomeKit versions integrate more directly. If you want simple app-based remote access without an extra hub, August with Wi‑Fi or the August Connect bridge is easier.

Features comparison: convenience and daily use
Both locks aim to make coming and going simpler. Here’s how their features stack up.
Yale Assure key features
- Keypad entry on many models for code-based access.
- Full deadbolt replacement option adds a traditional locked feel.
- Hub-ready modules for Z-Wave, Zigbee, or HomeKit.
- Auto-lock options via hub automation.
August key features
- Retrofit keeps your external key and hardware.
- Auto-lock and auto-unlock using geolocation.
- Easy guest access with time-limited virtual keys.
- DoorSense (in some models) to detect if the door is open or closed.
Practical example: I used August on a short-term rental to send temporary codes to guests. The app made issuing and revoking access painless. For my house where I wanted a keypad and HomeKit control, Yale Assure was the better fit.

Security and privacy: how safe are Yale and August locks?
Security matters most with smart locks. Both brands follow industry standards, but details differ.
Yale Assure security elements
- Uses tamper-resistant deadbolt designs on full replacement models.
- Modules like Z-Wave support encrypted communications when used with secure hubs.
- Keypad models can be vulnerable if PINs are weak; enforce strong codes.
August security elements
- Keeps the original deadbolt, so the mechanical security depends partly on your existing hardware.
- App and cloud services use encryption. Two-factor options vary.
- DoorSense that confirms closed/locked state adds a layer of safety.
Security tips
- Use strong, unique PINs and change default codes.
- Enable two-factor authentication where available.
- Keep firmware updated for both Yale and August units.
Experience-based caution: I once found a user with a weak, shared keypad code on a Yale lock. Changing to unique, per-user codes eliminated casual access risks immediately.

Performance and reliability: battery life, speed, and durability
Both locks run on batteries. Expect months of battery life depending on use and features.
Performance notes
- Yale Assure battery life is generally solid; keypad backlighting and frequent operations shorten life.
- August battery life depends on Bluetooth usage and Wi‑Fi bridging; heavy remote unlocks use more power.
- Motors can wear over years. Regular updates and checks improve longevity.
Troubleshooting tips
- Keep spare batteries at home. Many locks warn via app when power is low.
- Recalibrate motors if lock jams or loses sync.
- Tighten interior screws periodically to prevent motor strain.
Price, plans, and total cost of ownership
Cost includes hardware, optional hub or bridge, and subscription features for some services.
Price factors
- Yale Assure models range in price based on features, finishes, and smart modules. Adding a Z‑Wave or HomeKit module raises cost.
- August base units are affordable; adding the Wi‑Fi bridge or subscribing to advanced services can increase expenses.
- Consider hidden costs: professional installation, hub purchase, and ongoing cloud subscriptions.
Value advice: If you want remote features without a hub, budget for the August Connect or a Yale model with built-in Wi‑Fi or compatible hub. For long-term installations, a well-integrated Yale Assure with a smart hub can be a better investment.
Use cases: which lock fits your needs
Compare use cases to pick the right product for your situation.
Best for renters or non-invasive installs

My recommendation from experience: choose August when you need a fast retrofit solution. Choose Yale Assure when you want a polished finish and deeper hub-based automation.
Practical tips, common mistakes, and lessons learned
Here are hands-on tips from installing and using both locks.
Top tips
- Measure door specs before purchasing. Save time and returns.
