Make room for what matters

Check your door before choosing a smart lock

Choose home improvement tools and fittings for the door you already have. This page focuses on the ULTRALOQ U-Bolt Pro Bluetooth smart lock. Check physical fit first, then decide how you want to control access.

Home improvement tools: make door fit the first check

  • The existing door
    Measure door thickness, the face hole and the backset using the manufacturer's diagram. Check handle and trim clearance as well as the lock opening.
  • The exact version
    Match the Bluetooth U-Bolt Pro to its own instructions. Do not borrow Wi-Fi, Z-Wave or other connected features from a different version in the family.
  • Access when you need it
    Read the supported access methods, battery guidance and backup-entry instructions. Plan how household members will use the lock before ordering.

Separate nearby control from remote access

U-tec's U-Bolt Pro guidance distinguishes the Bluetooth version from other variants. It says the Bluetooth version needs an additional Wi-Fi adaptor for an internet connection. Confirm whether that adaptor is included in your chosen package if remote control is a requirement.

Also compare your door measurements with the current installation diagram. The maker offers a separate thick-door kit for specified door thicknesses. Do not assume that one fitting range or accessory package applies to every U-Bolt Pro listing.

Explore the product for your shortlist

Match these options to your space, devices and daily routine. Then check the exact model and the parts in the box.

Check installation and the package before purchase

Read the installation steps from start to finish and identify the tools and hardware needed. Make sure the existing door and latch work properly, and check whether the changes are permitted if you rent the property.

Then confirm the included lock components, keys and any connectivity accessory. Keep physical fit, network requirements and the access routine on separate lines in your checklist. A feature-rich lock is not useful if it does not fit the intended door.

Questions that change your choice

Does Bluetooth mean you can control the lock from anywhere?

No. Check the exact model's remote-access requirements. U-tec specifies an additional Wi-Fi adaptor for the Bluetooth U-Bolt Pro's internet connection.

What if your door measurement falls outside the standard range?

Check the maker's compatibility guidance and any specified kit before ordering. Do not modify the door or choose a substitute fitting on the assumption that all versions install identically.
