Level Lock vs August Smart Lock Pro — Which One Gets Nuked?

Quick Verdict: The Level Lock is the clear winner for homeowners who prioritize aesthetics, retrofit compatibility, and traditional key functionality. It's the only smart lock that disappears completely into your existing deadbolt, leaving your door looking untouched while delivering full smart home control. August Smart Lock Pro is the runner-up — it's cheaper and easier to install, but you're stuck with visible hardware and mediocre battery life.

Overview

Level Lock and August Smart Lock Pro represent two fundamentally different philosophies in smart lock design. Level Lock is an invisible retrofit mechanism that installs inside your existing deadbolt cylinder, while August is a surface-mounted device that attaches over your current lock. Level Lock targets design-conscious homeowners who want smart features without sacrificing their door's appearance. August targets convenience-first buyers who want quick installation and don't mind visible smart hardware. These products appeal to different priorities, but when you're choosing the objectively better lock, Level Lock wins on nearly every architectural and functional metric.

Head to Head

Price: August Smart Lock Pro costs $250–$300, undercutting Level Lock's $350–$400 range by roughly 30 percent. However, that price difference evaporates when you factor in Level Lock's invisibility and superior feature set. August's lower price reflects its more basic design and shorter battery life.

Installation: August installs in minutes on top of your existing deadbolt — no tools, no modifications. Level Lock requires professional installation or significant DIY skill since it replaces the interior mechanism of your deadbolt. Installation time matters for convenience, but the cost of a Level Lock pro installation is typically $200–$300, still keeping the total under $700. August's ease here is real, but it's offset by its permanent aesthetic compromise.

Access Methods: Both offer app control, voice assistant integration, and PIN pad entry. Level Lock preserves your physical key as a backup — an underrated feature that lets guests, housekeepers, and family members use traditional keys without learning a PIN or installing an app. August also supports physical keys, but its surface-mounted design makes key operation feel awkward since the smart lock module sits between you and the actual mechanism. Level Lock's key integration is seamless because the smart mechanism is hidden inside.

Smart Home Integration: August Smart Lock Pro supports more ecosystems (Apple HomeKit, Google Home, Alexa, and Samsung SmartThings) compared to Level Lock's HomeKit, Google Home, and Alexa. For most users, that difference is irrelevant — the three major ecosystems cover 95 percent of the market. August's SmartThings support is nice but rarely the deciding factor.

Battery Life: Level Lock delivers 12+ months per charge, while August requires battery replacement every 3 months. This is a massive real-world advantage for Level Lock. With August, you're buying batteries four times per year and potentially facing lockouts if you forget. Level Lock's longer battery life reflects its more efficient mechanism and superior engineering.

Who Should Buy the Level Lock

Buy Level Lock if your door's appearance matters to you — and it should, because your front door is one of the most visible architectural elements of your home. If you own a vintage deadbolt, care about your door's design, or plan to stay in your home for several years, Level Lock's invisibility is transformative. It's also ideal if you have frequent guests or service providers (contractors, cleaners, family) who benefit from using their existing keys rather than managing digital access. Professional installers, designers, and anyone selling a home in the next five years should strongly prefer Level Lock because it adds premium smart security without visual compromise. If smart home reliability matters more than installation convenience, Level Lock's superior battery life means one less thing to worry about every three months.

Who Should Buy the August Smart Lock Pro

August Smart Lock Pro is legitimately the right choice if you prioritize installation speed and don't mind visible hardware. Renters who can't modify their deadbolts should absolutely choose August because it requires zero permanent changes. First-time smart lock buyers who want to test the category without professional installation will find August more approachable. If you absolutely need Samsung SmartThings integration and can't use HomeKit or Google Home, August's broader ecosystem support might justify the compromise. August is also the better choice if you're budget-constrained and want the lowest upfront cost. Just accept that you'll replace batteries three times per year and your door will have obvious smart lock hardware visible to everyone who approaches your entrance.

Our Pick

Level Lock is the superior smart lock product. It solves the fundamental problem that plagues every other smart lock: visibility. August and its competitors force you to choose between smart security and aesthetic compromise. Level Lock eliminates that trade-off entirely by hiding inside your existing deadbolt. The longer battery life, superior key integration, retrofit compatibility, and overall engineering quality justify the higher price. Installation requires professional help or technical skill, but that's a one-time cost for a product you'll own for 5-10 years. For a permanent home upgrade, Level Lock is the obvious winner. For renters or anyone who absolutely must minimize installation friction, August remains a solid alternative — but it's the compromise choice, not the superior one.
