We discuss how you use your door—keys, codes, app, integration with alarm or cameras—and recommend the right lock for your San Diego County home.
We choose a smart lock that fits your door type and thickness and works with your preferred app or smart home system.
Our technicians remove the old lock, install the smart lock, and ensure proper alignment and weather sealing for coastal conditions.
We program codes and connect the lock to your app so you can lock, unlock, and manage access from your phone.
We show you how to add and remove codes, use the app, and integrate with alarm or cameras if applicable.
