With the SmartCode 10 you can upgrade to a more convenient, controlled keyless entry deadbolt that offers you up to 16 user codes! You can enter your home with a few simple key pushes and lock it when you leave with just one. You also have more control over who has access to your home. You can assign a temporary user code to whoever in your life needs one, then delete it when you see fit. The SmartCode 10 eliminates the need for keys! It’s easy to install, program, and use and operates on four AA batteries. The SmartCode 10 complements any Weiser knob, lever or handleset.
