An app-based lock shifts access management from physical hardware to a secure digital interface. By connecting the lock to your smartphone via Bluetooth or Wi-Fi, you gain the ability to lock and unlock the door remotely, monitor real-time entry logs, and receive instant tamper alerts. The real value for most users is the 'e-key' functionality—the ability to text a temporary access code to a guest or service provider that expires after a set time. It’s a highly efficient solution for rental property owners or busy households who want to eliminate the risk of lost keys and the expense of re-keying locks every time a tenant moves out or a cleaner changes.
