Your Aegis smart door lock can use the Sentry video doorbell as a gateway to connect to the internet (if you purchased just the Aegis door lock, there should be a separate gateway device that serves the same purpose). You can also use the fingerprint reader to unlock the door lock.
First, ensure that your Sentry doorbell has the fingerprint reader module. The module is included if you purchased the Aegis Smart Door Lock + Sentry Video Doorbell bundle.
Install and set up both your Aegis and Sentry. Note that both devices must be registered under the same account and the same family, and that they’re no more than about 15ft apart, as their connection is Bluetooth-based. If they’re not under the same account, please follow this FAQ to move one of the to the other account. If they’re not under the same family, please follow this FAQ to add the one not in the family to the family.
Then, go to Sentry home page –> Settings (⚙️ button at the top right corner) –> Fingerprint Reader, and add your Aegis door lock under “Paired Devices.” Don’t forget to enable “Unlock” under “Fingerprint Actions” so that fingerprint scans can unlock the Aegis door lock. You can then add new fingerprints under “Fingerprints.”
