With an interactive touchscreen that can be programmed right at the lock, Yale’s Assure lock deadbolt is very easy to use and put in and even boasts voice-guided assistance. It can be installed with a screwdriver and fits in a regular deadbolt lock space. The touchscreen is also illuminated so not a strain to use at night. The lock has 12 buttons in the pattern of a standard phone layout, and it’s a snap to set up PIN codes for new users, adding an extra level of convenience to home security. The lock even has voice guidance in three languages to walk you through set up and customizing settings.
