(This review was collected as part of a promotion.) My husband installed this electronic deadbolt at our cottage in 8 minutes! Very easy to do. It looks fantastic on our front door and matches our existing Weiser knob. The electronic deadbolt is perfect for a cottage or second home because we don't constantly have to be fumbling with keys. If the kids or guests come up from the beach we simply have to give them the code to get back into the house. I also like how this deadbolt has an automatic lock function which our prior model did not. It gives you peace of mind especially when you're renting. There is also an option to program specific user codes and a couple one time use codes. We love this product! Weiser never fails to disappoint in providing quality home products.
