Simply more secure.
This unedited video (of a prototype) shows how fast and easy it is to install Sabrelock over an existing door lock.
A mounting plate attaches quickly to the door, and Sabrelock fits over it, snapping firmly into place.
It's clean, quick and no tools are needed. A convenient key fob locks/unlocks the door. It's that simple.
Stronger security than a standard deadbolt.
