ULTRALOQ Bolt NFC Smart Lock: Supports Apple Home Key and Android NFC
Your home security lock should do more than just secure a door. It should give you control. The ULTRALOQ Bolt NFC Smart Lock makes it easy to let in the dog walker at 2 PM while you're at work, or unlock for the plumber without handing out a key. Tap your iPhone, Apple Watch, or Android phone to unlock instantly—even when your phone battery is dead. No app or wake-up needed.
Stop worrying about whether you left the door unlocked. The smart auto-lock feature secures your door every time it closes when used with the door sensor. Bluetooth auto-unlock greets you hands-free as you approach. You get real-time notifications and can check the lock history from the app. Set up Siri, Alexa, or Google voice commands to lock without lifting a finger.
Install it yourself in under 10 minutes with just a screwdriver. Eight AA batteries last up to a year. The Bolt NFC is BHMA certified for residential security. It withstands weather extremes and works reliably. Enjoy lifetime mechanical and 18-month electronic warranty, plus live phone support. This lock gives you true peace of mind.
