[This review was collected as part of a promotion.] I have purchased four of these products… So much more convenient not to have to fumble for a key. And my kids can enter without losing keys also.
[This review was collected as part of a promotion.] I had a different model, but very similar keypad on an exterior door. It lasted approximately three years before it started to intermittently, not engage the lock when you were leaving. Unfortunately, I have had to replace that with this but hopefully I get more than three years out of it.
