What Homeowners Should Know About August WiFi Smart Lock Review

The August WiFi Smart Lock has become one of the more widely discussed wifi enabled smart lock options available at major retailers, including August smart lock at Home Depot locations across the US and Canada. Homeowners researching an August wifi smart lock review often find plenty of coverage of app features and voice assistant compatibility, but far less guidance on the security trade-offs, installation risks, and scenarios where a professional locksmith should be part of the process. This post fills that gap with a straightforward, technical look at what the lock does well, where it falls short, and how to protect your home when adopting this technology.
What Homeowners Should Know About August WiFi Smart Lock Review Overview
The August WiFi Smart Lock — currently in its fourth-generation form — is a retrofit device, meaning it replaces only the interior thumb-turn of an existing deadbolt rather than the entire lock cylinder. The exterior hardware, including the keyway and the cylinder itself, remains unchanged. This is a meaningful design choice: residents retain a physical key option while gaining app-based access, auto-lock scheduling, and an activity log accessible from a smartphone.
Built-in WiFi (2.4 GHz) eliminates the need for the separate August Connect bridge that earlier models required. The lock pairs with Amazon Alexa, Google Assistant, and Apple HomeKit, and it integrates with a growing number of smart home platforms. Battery life is rated at approximately three to six months depending on usage, and the lock uses four AA batteries housed inside the interior assembly.
From a locksmith’s perspective, the retrofit approach is both the product’s practical strength and its most important security caveat. The lock’s resistance to forced entry, picking, and bumping is determined entirely by the underlying deadbolt cylinder — not by August’s hardware. A homeowner who installs this lock on a Grade 3 deadbolt has not meaningfully upgraded their physical security, regardless of the app’s sophistication.
Available in multiple finishes and compatible with most single-cylinder deadbolts, the August WiFi Smart Lock is sold at Home Depot and other major retailers at a retail price that typically positions it in the mid-range of the smart lock category. It is worth confirming compatibility with your existing deadbolt before purchase, as some mortise-style and multi-point lock configurations are not supported.
Key Factors
Understanding an August lock review requires separating the digital feature set from the physical security architecture. On the digital side, the lock offers guest access through the August app, time-limited virtual keys, and an access log that records every lock and unlock event. For landlords, Airbnb hosts, and households with regular service providers, these features deliver genuine convenience and accountability.
Auto-lock is one of the more practically useful features. The lock can be programmed to engage after a set interval — one, five, or fifteen minutes, for example — reducing the likelihood of a door being left unsecured accidentally. DoorSense, a small magnetic sensor included with the lock, detects whether the door is physically closed before the auto-lock cycle runs, preventing the motor from engaging against an open door frame.
WiFi connectivity introduces dependencies that purely mechanical locks do not have. The lock requires a functioning home network, adequate signal at the door, and operational cloud services to support remote access and real-time notifications. A network outage, router change, or August service interruption will affect app-based functionality. Physical key access and any locally stored access codes entered through the August keypad (sold separately) remain functional during outages, but remote management will not.
Encryption and authentication matter in any wifi enabled smart lock discussion. August uses TLS encryption for data in transit and requires two-factor authentication options for account access. However, the security of the overall system also depends on smartphone security hygiene — a compromised phone with the August app signed in represents a meaningful vulnerability. Homeowners should use strong, unique passwords for their August account and enable two-factor authentication without exception.
Costs and Risks
Average: $230 · Range: $180–$280 · Travel: free in service area. That reflects the retail cost of the lock itself. Professional installation by a licensed locksmith, where the technician verifies deadbolt compatibility, seats the interior assembly correctly, and confirms DoorSense alignment, typically adds $50–$120 depending on the market and any complications with the existing door hardware.
Hidden costs can emerge if the existing deadbolt is inadequate. If the underlying cylinder is a low-security unit — common in builder-grade hardware — a locksmith may recommend upgrading to a Grade 1 or Grade 2 deadbolt with an anti-pick, anti-bump cylinder before the August device is fitted. That upgrade, including hardware, typically runs $100–$250. Skipping it means the smart lock’s digital features are sitting on top of a cylinder that can be defeated with basic bypass tools.
Battery replacement is an ongoing operating cost. Four AA batteries every three to six months is a modest expense, but a dead battery that goes unnoticed can lock residents out. The August app sends low-battery notifications, and the lock emits audio and visual alerts, but these warnings are only useful if residents are monitoring them. Establishing a routine battery replacement schedule — or keeping a spare set inside — is a practical precaution.
Risk assessment for smart locks generally involves three categories: physical attack, digital attack, and operational failure. Physical attack risk is governed by the deadbolt cylinder, as discussed. Digital attack risk is low for most residential users but nonzero — credential stuffing against weak August account passwords is a documented attack vector across smart home platforms generally. Operational failure risk includes dead batteries, WiFi disruptions, motor malfunctions, and app errors. Homeowners who rely exclusively on the August app without retaining a physical key are taking on unnecessary operational risk.
When to Call a Locksmith
A locksmith should be involved at several points in the August WiFi Smart Lock lifecycle. Before purchase, a locksmith can assess the existing deadbolt, identify whether it is compatible with the August retrofit mechanism, and advise on whether the cylinder meets an adequate security grade. This consultation prevents the frustrating scenario of buying the lock, opening the packaging, and discovering that the existing hardware is incompatible or insufficient.
During installation, professional involvement is advisable when the door or frame shows signs of prior forced entry, when the door has an unusual thickness or configuration, or when the homeowner is uncertain about the alignment process for the DoorSense sensor. Improper installation can cause the auto-lock function to fail, the motor to strain against misaligned components, or the interior assembly to sit loosely — all of which shorten the product’s service life and reduce reliability.
If a lockout occurs related to the August lock — a dead battery with no physical key available, an app malfunction during a network outage, or a motor failure that prevents manual thumb-turn operation — a licensed locksmith can typically open the door without damage and diagnose whether the lock mechanism needs replacement. Attempting to force entry in these situations risks door frame and deadbolt damage that creates greater expense.
A locksmith is also the appropriate professional to call when a household member with previous app access — a former tenant, an ex-partner, or a terminated employee with a guest key — needs to be removed from access in a way that goes beyond app revocation. In cases where trust in the entire lock has been compromised, rekeying or replacing the underlying deadbolt cylinder provides a physical security reset that app access management alone cannot guarantee.
Recommended Next Steps
Before purchasing the August WiFi Smart Lock, confirm that the existing deadbolt is a standard single-cylinder unit with a tailpiece compatible with the August mechanism. The August website provides a compatibility checker, and the product packaging includes guidance, but a locksmith consultation removes ambiguity for non-standard doors.
Assess the quality of the existing deadbolt cylinder independently of the August decision. If the deadbolt is builder-grade hardware installed when the home was constructed and has never been replaced, upgrading the cylinder to a Grade 1 option with anti-pick and anti-bump features is worth the investment. The August lock will then function as a convenient access layer over a physically sound foundation rather than as a technology veneer over a weak one.
After installation, configure the August app fully before relying on it as a primary access method. Set up auto-lock, enable low-battery notifications, confirm DoorSense is reading correctly, and test the lock through several full cycles. Establish the account with a strong, unique password and enable two-factor authentication. Retain physical key copies and store at least one with a trusted person outside the household.
Review the activity log periodically. The log is one of the most practically useful features in the August ecosystem — it provides a timestamped record of every access event. Unexplained entries, access at unexpected hours, or entries attributed to guest keys that should no longer be active are signals worth investigating. If the log shows access that cannot be explained, contact August support and consult a locksmith about the appropriate physical security response.
For rental properties or homes with frequent guest access, consider pairing the August lock with an August Smart Keypad so that guests who lack smartphones or who experience app issues can still enter using a code. Manage codes carefully, issue time-limited access where possible, and delete codes immediately when they are no longer needed. A locksmith familiar with smart lock ecosystems can advise on access management practices appropriate for the specific property type.
