I bought this a month ago and I'm so glad I did. What a great idea! Now, if we ever go out of town, I can re-key a door or two and give a key to a neighbor and then, when we return, go back to having full security and peace of mind.

Super easy to re-key after you've done it once following the simple instructions. I love the beautiful chrome finish. 
High quality materials. Super easy to install. I would definitely recommend!
