Title: No Batteries
Review: This lock operates very smoothly and seems to be very strong. The install was easy but a drill is required since an extra bolt hole above the typical deadbolt hole is required. It is a very solid lock and the best thing is that no batteries are required. The only con is that the numbers can not light up for night entry. I had a battery operated deadbolt and this mechanical entry deadbolt is MUCH better.
