Who it fits
Good fit for
This lock suits homeowners who want multiple entry options without running new wiring. The keypad and app access are ideal for families sharing entry codes. Its ANSI Grade 1 rating and weatherproof build make it a reliable choice for exterior doors exposed to the elements. Users who value convenience will appreciate the auto unlock feature, which engages when your phone is near. It is also a good fit for those who need to grant temporary access to guests or service providers via the app.
Who should skip it
You should look elsewhere if you need native Wi-Fi connectivity without extra hardware. The U-Bolt requires a separate ULTRALOQ bridge for remote access and voice control features. If you prefer a lock that works entirely offline or without a smartphone, this model may not fit your needs. Additionally, if you want a lock with a built-in camera or video doorbell functionality, this deadbolt does not offer those features. You must also ensure your door is compatible with the standard deadbolt replacement size.
Verdict: The ULTRALOQ U-Bolt offers robust security and versatile entry methods for users comfortable with app-based management. It is a solid choice for standard doors needing a durable, multi-access smart lock.
ULTRALOQ U-Bolt Key Specs Explained
Access Methods: Keypad, app, auto unlock, key

Auto unlock detects your phone near the door to open it for you. You also retain two mechanical keys for traditional access. This variety ensures you are never locked out if one method fails, offering flexibility for different daily routines and emergency scenarios.
Connectivity: Bluetooth, 2.4 GHz Wi-Fi
The lock uses Bluetooth for direct communication with your phone when you are nearby. It supports 2.4 GHz Wi-Fi connectivity, but note that the product features mention a separate bridge is required for remote access when you are away from home. This dual connectivity ensures reliable local control. When comparing smart locks, verify if remote features require additional hardware purchases, as this affects your total setup cost and complexity.
Smart Home Compatibility: Alexa, Google Assistant, SmartThings
This deadbolt integrates with major voice assistants and automation platforms. You can lock or unlock the door using voice commands through Alexa or Google Assistant.

According to the listing, the ULTRALOQ U-Bolt measures 2.95 inches in width and length, with a height of 0.98 inches. It weighs three pounds and finishes in black. The model number is U-Bolt-BK. These dimensions allow it to replace a standard residential deadbolt on most left or right-handed doors. You can install it with just a screwdriver in about ten minutes.

Before You Buy This Smart Lock
You need to check your door type first. This lock fits most US standard doors, but you must confirm your handedness. You will also need a screwdriver for the ten-minute installation. The app allows you to manage access and view logs. However, remote access outside your home requires the ULTRALOQ bridge, which is sold separately. This is a key detail for many users.
