Why This Happens in Real Homes

This guide covers fit-check, mounting, and Matter onboarding so the lock works reliably in Apple Home, Google Home, SmartThings, or Alexa. In day-to-day use, this usually looks like New Yale Assure 2 in box; Existing deadbolt door; Matter-capable hub in home.
Most cases trace back to Wrong bore size on older doors; Thread router missing; Matter QR code damaged. The fix works best when you go step by step instead of changing multiple settings at once.
A practical order for this issue is: Check Door Prep -> Mount Exterior and Interior -> Install Batteries -> Pair With Matter. After each step, test the exact behavior that was failing so you can confirm what actually solved it.

Installation Steps
Check Door Prep
Use the Yale paper template to verify bore size and backset. Standard 2-1/8 inch cross bore and 1 inch edge bore are required. Correct prep first if either is off.
Mount Exterior and Interior
Feed the exterior assembly tailpiece through the bore. Secure the mounting plate to the door with supplied screws. Attach the interior housing without pinching the cable.
Install Batteries
Insert four fresh AA alkaline batteries in the correct orientation. The lock boots and plays a tone. If no tone, re-seat the battery pack fully and try again.
Pair With Matter
Open your ecosystem app, add accessory, scan the Matter QR on the lock body. A Thread border router handles the connection automatically. Name the lock and assign a room.
Calibrate and Test
Run the calibration sequence in the app to learn locked and unlocked positions. Lock and unlock three times. Adjust the strike plate if you hear binding.
Installation Tips
Still stuck? This is usually the deeper cause below.
Photograph the Matter QR before install. A clean copy on your phone helps if the original gets scratched during mounting.
