(This review was collected as part of a promotion.) Received the product to test and share my review from influster and here's my honest opinion. As someone who does basic household DIY projects replacing my basic old house lock with Weiser digital lock was as easy as 1,2,3. The instructions are straightforward and installation is fairly simple. It works with standard door and latch dimensions and I didn't have to do anything beyond unscrew the old and screw on this new one. The best part of digital lock is that we don't need to copy our keys to give to neighbors or extended family for emergencies or vacations.
