eufy Security Wi-Fi Smart Lock+Wireless Keypad, Keyless Entry Door Lock Replacement, Built-in Wi-Fi, Remote Control, in-App History and Scheduled Access, IP65 Waterproof, Fits Your Existing Deadbolt

Key features

• Ideal for Renters and Landlords: Easily install Retrofit Smart Locks in 10 minutes. They fit over your existing deadbolt on the inside of your door. The outside doesn’t change—giving access with the original keys—which you won’t need anymore.
• Remote Control, Anytime, Anywhere: Unlock Smart Lock anywhere, anytime, right from your phone via the eufy Security app.
• Auto Locking and Unlocking: A built-in sensor detects when your door is closed and locks it automatically behind you, keeping your home secure even when you’re in a hurry or if your hands are full. Auto unlocks when you approach with your iOS device (using location geofencing).
• 5 Ways to Unlock: Along with Auto Unlock, you can control your lock remotely via the app, by voice, with the included wireless keypad, and it can still be opened with the original keys.
• Advanced Security: Retrofit Smart Lock stores your in-app data locally using an AES128 encryption chip, rather than in the cloud, to keep your personal information safe and private.
