Everything about this deadbolt has been thought through.  The installation was under 15 minutes if you are replacing an old deadbolt.  The low profile looks great and secure.   I love the smart key technology because I’m using it on a side garage and like to change it often so I know who is coming in and out of my house.  Following the directions included makes the rekeying simple and quick.  Best of all it is secure and heavy duty.  You won’t be disappointed in this deadbolt.
