When you're looking for a secure way to lock and unlock your exterior doors, a single-cylinder deadbolt lock handleset is the perfect solution. These locksets are operated with a key from the outside, but do not require a key from the inside. Instead, they use a thumb-turn style lever or turn piece. This makes them ideal for securing entrances and front doors, where keyed entry is needed. Choose from elegant and appealing single-cylinder handleset designs that will add style to your home's exterior.
