(This review was collected as part of a promotion.) This has made such a difference in the ease at which we can leave and come home, especially when we’re going out without our keys, for an evening walk for example. It’s so easy to just punch the code in to enter or hit the lock button when heading out! My husband is an electrician so he’s quite handy but he said this was relatively straight forward to install. We wish we would have done it sooner!
