The slimmest, most secure lock on the market. No keyhole, no picking. Total 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 up with a touch, allowing you to enter with your personal code without fumbling for keys in the bottom of 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 opens 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 automatically unlocks it. Enter your home with groceries in hand without touching anything.
By eliminating the keyhole, we eliminate vulnerability. No one can use lock picks or master keys. If your battery runs out, use an external 9V charger for emergency power.
Visitors arrived and you're not home? 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 at specific times and delete them whenever you want.
Never wonder if you locked the door. Configure Auto-Lock to automatically bolt the door 30 seconds after closing it.
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 notify you weeks before they run out. If you ignore them and it completely dies, there are two terminals below the keypad. Touch them with a square 9V battery to provide 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 key). Your handle or knob below remains the same.
