August vs Schlage: Which Smart Lock is Right for You?
The debate between August and Schlage smart locks often comes down to a fundamental design philosophy. August focuses on retrofitting your existing lock, allowing you to keep your original key and deadbolt. Schlage, on the other hand, replaces the entire lock assembly, offering a more integrated security solution with features like a built-in alarm and physical key override.
Both brands are owned by Fortune Brands Home & Security (via Assa Abloy for August), but they target different users. We analyzed owner reviews from Amazon, Best Buy, and Home Depot, along with published spec sheets, to compare them on security, installation, app reliability, and ecosystem compatibility.
Security and Build Quality
Security is the most important factor. The Schlage Encode Plus is built to ANSI/BHMA Grade 1 standards, the highest residential rating for durability and forced entry resistance. It also includes a built-in alarm that sounds if someone tries to tamper with the lock. The physical key override provides a reliable backup if the battery dies. Owner reviews consistently praise the solid, heavy feel of the Schlage lock.
The August Wi-Fi Smart Lock relies on your existing deadbolt, which may or may not be Grade 1. While August locks are well-built, they lack a built-in alarm and do not include a physical key slot on the lock itself. If the battery dies, you must use the physical key on the exterior side, which requires the August lock to be correctly installed over your existing keyed cylinder. This is a point of confusion for some users in reviews.
Installation and Compatibility
Installation is where August has a clear advantage. The August lock is designed to fit over your existing single-cylinder deadbolt. You only need a screwdriver, and the process takes about 10 minutes. This makes it ideal for renters who cannot change the lock permanently or homeowners who love their current exterior hardware.
Schlage locks require a full replacement of the deadbolt. You will need to remove your old lock and install the new Schlage assembly. This is a bit more involved but still manageable for a DIYer. The benefit is a completely integrated system where the thumb turn, key cylinder, and electronics are all designed to work together seamlessly.
Smart Features and Ecosystem
Both locks offer Wi-Fi and Bluetooth connectivity, but their ecosystems differ. The Schlage Encode Plus is a standout for Apple users because it supports Apple Home Key. This allows you to unlock your door by simply tapping your iPhone or Apple Watch, even if the battery is dead (using NFC). It also supports Matter, making it compatible with all major smart home platforms now and in the future.
The August Wi-Fi Smart Lock works with Alexa, Google Assistant, and Apple Home (via HomeKit on some models), but it does not support Apple Home Key or Matter. August's strength is its DoorSense technology, which uses a sensor to tell you if the door is open, closed, or locked. This feature is highly rated for peace of mind. The August app is also known for its intuitive auto-unlock feature based on your phone's location.
Battery Life and Power
Both locks use 4 AA batteries and claim around one year of battery life under normal use. Owner reviews suggest the August lock can drain slightly faster if you use the auto-unlock feature frequently or have a weak Wi-Fi signal. The Schlage Encode Plus has a low-battery warning that is very reliable, and the physical key ensures you are never locked out. August also has a 9V battery terminal on the exterior for emergency power, which is a nice touch.
What to Check Before Buying a Smart Lock
- Door Thickness: Ensure your door is between 1-3/8" and 1-3/4" thick for standard installation.
- Backset: Most locks fit 2-3/8" or 2-3/4" backsets, but check your door's measurement.
- Existing Deadbolt: If you want August, your existing deadbolt must be a single-cylinder type (key outside, thumb turn inside).
- Smart Home Hub: If you use Apple Home, the Schlage Encode Plus with Home Key is a major advantage. For Alexa or Google users, both work well.
- Rental Agreement: Renters should check if they are allowed to change the lock. August is usually the safer choice.
Mistakes to Avoid
- Ignoring Wi-Fi Signal: A weak Wi-Fi signal at the door will cause connectivity issues. Use a Wi-Fi extender if needed.
- Forgetting the Physical Key: With August, you still need the physical key for backup. Keep it accessible outside or with a neighbor.
- Not Checking Door Alignment: A misaligned door can cause the latch to bind, draining batteries and causing lock failures.
- Choosing the Wrong Model: August has several generations. The 4th Gen Wi-Fi model is the best for most users. Schlage's Encode Plus is the only one with Home Key and Matter.
