This low profile deadbolt is beautiful! I love how sleek it is and how the finish is very modern. This will spruce up anyone’s door. It was quite simple to set up, one screw is all you need. I love that this has the option to rekey. I’ve never seen another product have this capability. I have renters who stay at my house and every few months they leave and the process starts over again. This gives me peace of mind knowing that once they leave, they don’t have the option of coming back in because I rekeyed they lock. To rekey the deadbolt is not difficult at all, just make sure to follow the instructions on the Manual as you do have to turn the key a certain way for it to work. 
The extra deadbolt on my door gives me security in knowing that someone can’t just kick in my door as easy as they could had I not installed the deadbolt. I love this on my door and you will too! Say goodbye to ugly deadbolts! Those are a thing of the past!
