How do August and Schlage window locks compare on installation?
The August Wi-Fi Smart Lock is designed for simplicity. It mounts over your existing deadbolt, meaning you keep your current key and exterior look. Installation takes roughly 10 minutes with just a screwdriver. Owner reviews on Amazon rate this as the easiest smart lock to install, with many saying they did it without reading the manual.
The Schlage Encode Plus requires a full deadbolt replacement. You remove your old deadbolt and install the Schlage unit, which includes a new key cylinder. This takes 20-30 minutes and requires a screwdriver and possibly a drill for the strike plate. Schlage includes clear instructions, but some owners report needing to adjust the alignment of the bolt.
Which lock has better security features?
Schlage holds the edge here. The Encode Plus carries an ANSI Grade 1 rating, the highest residential security standard. It features a hardened steel bolt and a pick-resistant cylinder. The lock also has a built-in alarm that sounds if someone tries to tamper with the lock or if the door is forced open.
August relies on your existing deadbolt for physical security, so its rating depends on what you already have. The August lock itself has no physical key override, which is a concern if the battery dies. However, it does have a 9V battery backup on the exterior. Schlage includes a physical key, giving you a fallback option.
Smart home compatibility and ecosystem
Both locks work with the major platforms: Amazon Alexa, Google Assistant, and Apple HomeKit. August has a slight edge with native Ring integration, making it a natural fit for Ring alarm users. The August app is well-reviewed for its simple interface and auto-lock/unlock features based on your phone's location.
Schlage Encode Plus supports Thread technology, which improves HomeKit performance and reliability. It also works with Samsung SmartThings and has a built-in Wi-Fi radio, so you don't need a separate hub for remote access. August requires the August Connect bridge (sold separately) for remote access, which adds cost and complexity.
Battery life and power management
Both locks use four AA batteries and claim 6-12 months of life. Owner reviews suggest real-world battery life averages 8-10 months for both, depending on usage. August sends low-battery alerts through its app. Schlage does the same and also has a low-battery chirp from the lock itself. Both locks allow you to use the keypad (Schlage) or phone (August) even when the battery is low, as long as there is some charge left.
What to check before buying a smart window lock
First, confirm your door's backset (the distance from the edge of the door to the center of the deadbolt hole). Most doors use 2-3/8 or 2-3/4 inches. Both August and Schlage fit standard doors, but measure to be sure. Second, check your door's thickness. Both locks work on standard 1-3/8 to 1-3/4 inch doors. Third, verify your Wi-Fi signal strength at the door. Smart locks need a stable connection to work reliably. Finally, consider whether you need a physical key. If you want a backup, Schlage is the better choice.
Mistakes to avoid when installing a smart lock
One common mistake is not checking the door alignment before installation. If your door is misaligned, the bolt may not slide smoothly, causing the motor to strain and drain the battery. Adjust the strike plate as needed. Another mistake is skipping the app setup instructions. Both locks require you to calibrate the lock during setup, which ensures the motor knows the correct positions for locked and unlocked. Skipping this step leads to false status reports. Finally, do not use rechargeable batteries. They have lower voltage than alkaline batteries and cause erratic lock behavior.
Which lock is more reliable based on owner reviews?
Aggregated reviews from Amazon and home improvement forums show Schlage Encode Plus has a slightly higher average rating (4.5 out of 5 stars) compared to August (4.3 out of 5 stars). Schlage owners praise the build quality and consistent performance. Common complaints about August include occasional disconnection from Wi-Fi and the need for the separate Connect bridge. Schlage complaints focus on the higher price and the more complex installation. Both brands have responsive customer support, but Schlage's warranty covers mechanical defects for the lifetime of the product, while August offers a one-year warranty.
August vs Schlage: Which is better for renters?
August is the clear winner for renters. Because it installs over your existing deadbolt, you can remove it when you move out without changing the lock. The landlord's key still works, and you take your smart lock with you. The Schlage Encode Plus requires replacing the entire deadbolt, which means you would need to reinstall the original lock when you leave. Many renters also prefer August's simpler setup, as it requires no drilling or permanent modifications to the door.
August vs Schlage: Which is better for homeowners?
Homeowners who want maximum security and a permanent solution should choose the Schlage Encode Plus. The ANSI Grade 1 rating provides peace of mind, and the built-in Wi-Fi eliminates the need for extra hubs. The physical key override is a practical backup. Homeowners who already use Ring security cameras or doorbells may prefer August for the seamless integration. However, the need for the August Connect bridge is a drawback for many.
