The 915 Smartcode Traditional Electronic Deadbolt is so fancy and sleek looking.  It's really easy to install.  It just took about 20 minutes, from start to finish. It comes with two keys. It auto locks after 30 seconds just in case you forget to lock it or if you're moving quickly and don't have time to lock it. It also has one touch locking. It has 16 user codes plus the master code feature which makes it very versatile. I would definitely recommend this lock to others.
