I have been eyeing electronic deadbolts for awhile and the Quikset 915 Smartcode did not disappoint!    It took about 30 minutes for my husband to install it and complete setup and it's beautiful!  I love that we can input up to 16 different codes to give to family members or a one time code to workers who may need to access the house in our absence.  You can use this unit with or without a key and I love the extra layer of security that comes with the requirement of entering the displayed 2 digit code before the access code to help throw off would be intruders trying to get in based on your fingerprint pattern.  My daughter loves this so much she never uses the garage door anymore and I don't have to worry about lost keys floating around!
