Start with the door, not the app.
Compare smart locks by installation format, entry methods, remote-access requirements, batteries and ecosystem support.
The short answer
A retrofit lock preserves the exterior hardware. A full replacement changes the deadbolt or lever. Before choosing either, measure the door, check backset and bore dimensions, inspect alignment and decide which physical fallback must remain available.
