ULTRALOQ U-Bolt WiFi Smart Lock with Door Sensor - Remote Control

In this review of the ULTRALOQ U-Bolt WiFi Smart Lock, the bottom line is straightforward: it is a versatile, feature-rich deadbolt aimed at homeowners, landlords, and short-term rental hosts who want remote control and flexible entry methods without adding a hub. The lock's biggest selling point is its direct 2.4GHz WiFi connectivity combined with a door sensor, which lets users lock, unlock, and monitor door status from anywhere using the smartphone app while still keeping mechanical key backup.

Key Features

• Remote control: The built-in 2.4GHz WiFi lets you lock, unlock, and check logs from anywhere using the smartphone app with no bridge required.
• 7-in-1 entry: Multiple entry options including anti-peep keypad, smartphone app, auto unlock, mechanical key, web portal, eKey sharing, and voice control give flexible access for family and guests.
• Door sensor: The included sensor reports open or closed status and sends alerts so you can know if the door was left ajar or opened unexpectedly.
• Auto lock and auto unlock: The lock can auto-lock when the door closes and auto-unlock as you approach, reducing the need to fumble with keys or the app.
• Weather resistant: IP65 rated exterior components are built to resist dust and weather, making the lock suitable for exposed front doors in many climates.
• Smart home integration: Works with Alexa, Google Assistant, SmartThings, and IFTTT so you can add voice control and automations to existing setups.

Who It's For

The U-Bolt is best for homeowners and property managers who want full remote access, shareable eKeys, and an integrated door sensor without installing a separate bridge; it fits most US standard left- or right-handed doors and installs with a screwdriver in about 10 minutes. It is also a good match for Airbnb or rental hosts who need to issue temporary codes or monitor entry logs remotely.

Users who need 5 GHz WiFi support or who demand flawless, instant reliability in every environment should consider alternatives; some customers report mixed experiences with WiFi connectivity, auto-lock timing, and battery life in specific installations, so those with marginal WiFi at the door should test signal or add a dedicated extender.
