What a Deadbolt Retrofit Smart Lock Is
A deadbolt-only smart lock is a motorized unit that turns your existing deadbolt from the inside. You keep the exterior faceplate and the original keyed cylinder. The device clamps to the interior thumbturn and uses an adapter to grip the spindle.
A small motor provides the torque to throw and retract the bolt. Power comes from replaceable batteries tucked inside the housing. Your metal bolt and strike stay the same, so door strength doesn’t change. You still have a physical key for backup and emergencies.
Installation usually needs only a screwdriver and takes minutes. No new holes. No trim replacement. The lock calibrates the throw length and checks for smooth travel. Many models add optional keypads or readers outside without touching the deadbolt body.
Control happens through an app or paired bridge for remote access. You can set auto-lock, share time-bound access, and review entry logs. It’s a clean upgrade that modernizes security while preserving your door’s look.
