What is Schlage LiNK? Schlage LiNK is more than a lockset. It's a brilliant new system that enhances your home's security, and your family's peace of mind — offering a new level of freedom to home security. In many ways, Schlage LiNK is like our other keypad locks. It uses proven Schlage construction derived from a rich heritage in commercial security. But there's another side to Schlage LiNK — one that brings you a whole new level of freedom. Schlage LiNK allows you to remotely monitor your doors and grant entry to your home. From any computer or cell phone with an internet connection, you can unlock your door, monitor who's coming and going, and even receive text message alerts from the system. What's more, because Schlage LiNK provides fully encrypted communication between the lock and the user (similar to the security used in on-line banking) your access and online information is safe and secure.
