The slimmest and most secure lock on the market. No keyhole, no picking. Full control from your phone with August technology.
Modernize your front door with the Yale Assure Lock SL, the world's sleekest and slimmest smart lock. Its revolutionary design is 100% key-free, meaning there's no cylinder for burglars to manipulate or force. Instead, it features a backlit touchscreen that wakes with a touch, allowing you to enter with your personal code without fumbling for keys in your bag.
This version is the most complete because it includes the 'Connected by August' kit. This connects the lock to your Wi-Fi and enables premium features like Auto-Unlock (the door unlocks automatically when you arrive home) and voice control with Alexa, Google Assistant, and Siri (HomeKit). Plus, with the DoorSense™ sensor, you'll know not only if the door is locked, but if it's actually closed or if it was left ajar.
Pure magic. Thanks to August technology, the lock detects when your phone approaches the door and unlocks it automatically. Enter your home with groceries in hand without touching a thing.
By eliminating the keyhole, we eliminate vulnerability. No one can use picks or master keys. If you run out of battery, use an external 9V charger for emergency power.
Visitors arrived and you're not there? Open the door from the office or the beach using the App. You can also view the history of who entered and at what time.
Share virtual keys, not physical copies.
Create unique codes for guests, dog walkers, or cleaning services. Set them to work only during specific times and delete them whenever you want.
Never wonder if you locked the door. Set Auto-Lock to deadbolt automatically 30 seconds after the door closes.
Compatible with the ecosystem you already use: Apple HomeKit, Amazon Alexa, and Google Home. 'Alexa, lock the front door'.
The exterior keypad has a weather-resistant rubber gasket, enduring rain, heat, and cold without issues.

The lock will warn you weeks before they run out. If you ignore them and it dies completely, there are two terminals under the keypad. Touch them with a 9V square battery to give it temporary power, enter your code, and get in.
Not with this model (CBA). This kit includes the August smart module and the Wi-Fi Connect bridge to plug into the wall, so it comes ready to connect to the internet.
Yes. This lock only replaces the deadbolt part (the security lock). Your handle or knob below remains the same.
