Lockare is an invisible-from-outside smart door lock that uses its own unbreakable lock system. Lockare cant be drilled out because there is no cylinder as in traditional locks. Furthermore, there is no mechanical key for Lockare. Lockare users can open the door using an RFID-chip or via Bluetooth from an application in their phone. The Lockare app also enables users to share a temporary key with their welcome guests and to revoke it from unwelcome ones.
