August Wi-Fi Smart Lock 4th Gen Review: Pros, Cons, and Verdict

We review smart locks around retrofit fit, backup access, and caregiver-friendly entry, with extra attention to older adults who want fewer steps at the door.

Quick Take

August Wi-Fi Smart Lock 4th Gen wins on discretion. It sits on the inside, keeps the exterior deadbolt look, and gives family remote access without a full hardware swap. The trade-off is blunt, there is no built-in keypad, so this is not the easiest answer for a front door that serves visitors who do not use smartphones.

For seniors, the real question is simple: does the person at the door need a phone, or do they need the lock to just work. August favors the first answer. Schlage and Yale favor the second.

Initial Read

August gets the door out of the way, and that is its biggest visual win. The inside-only design keeps the front of the house looking familiar, which matters for older adults who do not want a big hardware change on the door they use every day.

That same restraint creates a limitation. If you want a keypad that grandkids, aides, or neighbors can use without an app, August does not deliver that out of the box. You either add the separate keypad accessory or step up to a full keypad deadbolt from Schlage or Yale.

Core Specs

The meaningful specs on this lock are the ones that change daily use, not the ones that sound flashy in a product pitch.

The best way to read this spec sheet is plain: August is built to preserve the door you already have. That lowers visual clutter and install disruption, but it also shifts the burden onto the deadbolt underneath it.

Main Strengths

August does its best work in homes that already have a reliable deadbolt and want smarter access without a visible overhaul. That is a real advantage for older adults who value familiar hardware and for families who want to share access remotely instead of passing keys around.

The remote control side also matters more than many guides admit. A caregiver checking whether the door is locked after a late visit gets real peace of mind from app access, and adult children can manage entry without changing the door’s look. Schlage Encode Smart WiFi Deadbolt does keypad convenience better, but August wins when the goal is to keep the outside of the house calm and unchanged.

The drawback sits beside the strength. Less hardware means less door-side convenience, and the lock still depends on a healthy battery and a smooth-turning deadbolt.

Main Drawbacks

Most guides treat app control as the main selling point. That is wrong for many senior homes, because the front door must work for guests and family without a lesson. August does not include a built-in keypad, so every phone-free workflow needs an add-on or a different lock.

That trade-off matters every single day. If the door gets used by people who do not want to learn an app, Schlage Encode Smart WiFi Deadbolt or Yale Assure Lock 2 makes more sense. August also puts more weight on battery management than a plain mechanical deadbolt, and that extra upkeep becomes noticeable the first time the lock needs attention after a busy week.

A second drawback is fit sensitivity. A smart retrofit lock does not forgive a sticky deadbolt, a sagging door, or a sloppy strike plate. If the underlying hardware fights back, the smart features lose their shine fast.

What Most Buyers Miss

The hidden trade-off is not smart features versus old-fashioned keys. It is convenience on the app side versus reliability at the door. August keeps the door looking simple, but the actual system now includes the lock, the batteries, the app, and the underlying deadbolt, and every piece has to stay in sync.

That matters even more for secondhand buyers. A used August lock needs complete mounting hardware, a clean factory reset, and account access fully removed by the previous owner. Missing pieces or a sloppy reset turn a deal into a headache, and smart-lock headaches are harder on seniors than a standard lock problem because they involve both hardware and software.

Compared With Rivals

Against Schlage Encode Smart WiFi Deadbolt, August is cleaner on the door and easier to live with visually. Schlage wins when the household wants keypad entry at the front door and no separate accessory to manage. That is the better choice for a visitor-heavy home or for anyone who wants a code pad to do the heavy lifting.

Against Yale Assure Lock 2, August keeps more of the original door setup intact. Yale wins when the priority is a straightforward keypad deadbolt with fewer software layers. August wins when preserving the existing keyway and exterior hardware matters more than having a built-in code pad.

If we had to reduce the choice to one sentence, it is this: August is the retrofit specialist, Schlage and Yale are the door-first specialists.

Best Fit Buyers

Best fit

August fits a senior household that already has a good deadbolt, wants remote access for family, and cares about keeping the front door looking familiar. It also fits homes where adult children or caregivers handle part of the access setup.

Not the fit

August does not fit a front door that needs a keypad as the primary entry method. It also does not fit a user who refuses app setup or wants the lock to behave like a simple standalone deadbolt with no battery planning.

Who Should Look Elsewhere

Skip August if the door has a sticky throw, an odd alignment problem, or a history of binding in cold or humid weather. Smart features do not rescue a weak mechanical lock. They expose it.

Skip it too if the family needs one simple entry path for everyone. That is Schlage Encode Smart WiFi Deadbolt territory, or Yale Assure Lock 2 if the look and feature set fit better. For a phone-averse senior, keypad-first wins every time.

Long-Term Ownership

Long-term ownership on a retrofit smart lock is about routine, not drama. Batteries become part of the calendar. Access sharing becomes part of household management. App support and account control become part of the lock, whether buyers want them or not.

We lack hard data on every unit past year 3, so the practical long-term questions are simple: does the app stay stable, do the batteries fit the household routine, and does the lock still pair cleanly when something gets reset. That is the part most product pages skip, and it is the part that decides whether the lock feels easy or annoying after the novelty wears off.

Durability and Failure Points

The first failure point is usually not the motor. It is the door. A deadbolt that sticks, a strike plate that drags, or a door that shifts with the seasons creates friction before the electronics do.

Battery drain and connectivity are next. If the lock leans on auto-lock or sees a weak Wi-Fi signal, the convenience layer gets less graceful. The physical key remains the clean fallback, which is exactly why keeping that original keyway matters so much here.

For seniors, that is the key takeaway: buy the mechanical fit first, the smart features second.

The Real Trade-Off

August Wi-Fi Smart Lock 4th Gen is a smart overlay, not a fresh start. That is why it feels elegant on a good door and frustrating on a bad one.

The payoff is discretion and retrofit ease. The price is keypad absence and a heavier reliance on batteries, app access, and a healthy deadbolt. If the household values those trade-offs, August lands well. If not, a keypad deadbolt from Schlage or Yale is the cleaner call.

Final Call

We recommend August Wi-Fi Smart Lock 4th Gen for homes that want discreet retrofit access, remote family control, and a door that keeps its original look. That makes it a strong senior-friendly choice when the existing deadbolt already works well.

We do not recommend it for front doors that need a built-in keypad, or for households that want the lock to stay simple for every visitor. In those homes, Schlage Encode Smart WiFi Deadbolt or Yale Assure Lock 2 fits the job better.

Frequently Asked Questions

Does August Wi-Fi Smart Lock 4th Gen keep my existing key?

Yes. It works with the deadbolt already on the door, so the physical key remains part of the setup. That matters for older adults who want a fallback that does not depend on a phone. The trade-off is that the old deadbolt has to turn smoothly.

Is it a good lock for seniors who do not want to use a phone every time?

No. It works best when a phone, shared digital access, or a separate keypad accessory is part of the routine. If the goal is simple code entry at the front door, Schlage Encode Smart WiFi Deadbolt or Yale Assure Lock 2 fits better.

Do we need the August keypad accessory?

Yes, if the home needs code-based entry without a phone. The lock itself does not give you the same built-in keypad convenience as a keypad deadbolt. That extra piece also adds another item to maintain.

What happens if the Wi-Fi goes out?

The physical key remains the fallback, and that is the part that matters most. Remote features and app control lose convenience until the connection returns. That is another reason the mechanical deadbolt has to be in good shape before you buy.

Is August better than Schlage Encode Smart WiFi Deadbolt?

August is better when you want to keep the door looking familiar and preserve the existing deadbolt setup. Schlage Encode is better when keypad entry at the door matters most. For many senior households, Schlage wins the convenience battle, while August wins the appearance and retrofit battle.

Should we buy a used one?

Only with caution. Smart locks depend on complete mounting hardware, a proper reset, and a clean account handoff from the previous owner. Missing parts or a sloppy reset turn a bargain into install frustration.

Is this lock a good fit for aging in place?

Yes, if the home already has a smooth deadbolt and someone comfortable with app setup handles access management. It is not the best stand-alone choice for a senior who needs every entry to work without a phone. For that use case, a keypad-first lock does the job better.
