Why The August Wi-Fi Smart Lock Is The Best Deadbolt Upgrade For Renters & Owners
Replacing your entire front door deadbolt is a hassle: you have to give up your existing keys, re-key matching locks, or face lease violations if you rent. The August Wi-Fi Smart Lock (4th Generation) solves this with pure mechanical genius.
It installs strictly on the inside of your front door, attaching directly to your existing deadbolt thumbturn. Your exterior door hardware and physical metal house keys remain 100% unchanged. Inside, motorized gears lock and unlock your door automatically, pairing directly to your home Wi-Fi with no bulky plug-in bridges required.
The August Wi-Fi Smart Deadbolt Lock retrofits onto existing deadbolts in 10 minutes without changing exterior keys. Featuring built-in Wi-Fi, DoorSense open/close verification, auto-unlock on approach, and seamless Apple HomeKit/Alexa integration, it provides secure keyless entry for homeowners and renters alike.
