TL;DR: To set up a smart lock with a doorbell, first install the lock and connect it to your Wi-Fi, then pair the doorbell in the same app so both devices trigger unified alerts. This guide walks you through mounting, pairing, and testing your system in about 30 minutes.
Step 1: Check Compatibility and Gather Tools
Confirm your door thickness, backset, and deadbolt type match the smart lock’s specs. You will need a screwdriver, the lock’s mounting plate, batteries, and your phone with the manufacturer’s app installed.

Step 2: Remove the Old Lock and Doorbell
Unscrew the existing deadbolt and pull the cylinder free. Next, remove your old doorbell button from the exterior wall, but leave the two low-voltage wires exposed and avoid letting them touch.
Step 3: Install the Smart Lock
Slide the new latch into the door edge and screw it in. Mount the interior and exterior keypad assemblies, connecting the ribbon cable if your model requires it. Insert batteries and let the lock run its calibration cycle.
Step 4: Wire and Mount the Smart Doorbell
Attach the doorbell’s wires to the terminals, secure the mounting bracket, and snap the camera unit into place. If your doorbell needs a chime adapter, install it inside your mechanical chime box now.
Step 5: Pair Both Devices in One App
Open the app, add the smart lock first, and name it clearly, such as “Front Door Lock.” Then add the doorbell and assign it to the same room or home profile so events appear in one feed.
Step 6: Link Automations and Test
Create a routine that unlocks the door when the doorbell recognizes a known face, or sends a notification when motion is detected. Test locking, unlocking, two-way audio, and video recording before relying on the system.
Tips
Update firmware immediately after pairing. Keep a physical key as backup, and never share temporary access codes over unsecured channels.
