Our automated/smart door locks are manufactured by major brands, such as Kwikset, Yale, and Schlege. All of our locks have an external keypad and some give the user the option/ability to still lock or unlock the door with a key. Most locks also have a "smart key" feature which allow the user to program their existing keys without having to call a lock smith to re key locks. This option make them an excellent choice for retrofitting into an existing home or office location. Our locks allow multiple user codes which can be assigned to different users or family members. This can be important especially with alerts and notifications which can be set when a code is entered into the door keypad. This can be used when children are present to notify when arriving home from school. Of course all of our automated locks can allow remote access assigned to specific users, which means it can be locked or unlocked from any remote location.
