Prepare the door before fitting new hardware
Good preparation reduces misalignment, unnecessary drilling, and setup problems. Use this guide to inspect the door, record key measurements, and plan the first test before installing a smart lock or connected handle.
Inspect and measure
Record door thickness, backset, latch dimensions, handle spacing, frame clearance, and the direction the door opens. Check that the door closes freely before adding powered hardware, because alignment problems can strain the mechanism.
Prepare power and connection
Identify the battery type and access point, then choose a replacement routine that is easy to follow. If the device uses a wireless connection, check the expected signal at the door and understand which functions work when that connection is absent.
Test every entry path
After fitting, test locking and unlocking from both sides, indoor release, codes, phone control, alerts, and the stated fallback method. Test with the door open first, then repeat with the door closed while keeping another entry route available.
Clear answers before the next step
Should the door close before installation?
Yes. A door that rubs, shifts, or needs force can create problems for powered hardware. Correct the underlying alignment issue before fitting a new device.
What is the safest first test?
Test the mechanism with the door open, verify each access method, and keep an independent way into the home before closing the door for further tests.
