(This review was collected as part of a promotion.) Sooo normally when my husband and I try to do what should be a simple task together, something goes wrong and it takes way longer then expected…well to my surprise this actually was easy to install! Start to finish, it maybe took us 15 minutes. That includes removing the old lock, installing the new, and programming the codes! I love it so much already, we should have got this years ago. It works perfectly!!
